There is no single answer to this one: it depends on what you are measuring. 10 grams of flour is 4 teaspoons, while the same amount of granulated sugar is 2.42 teaspoons. The table below covers ten ingredients that come up most.
Grams to teaspoons, by ingredient
| Ingredient | 10 grams | 20 grams | Weight per cup |
|---|---|---|---|
| All-purpose flour | 4 teaspoons | 8 teaspoons | 120 g |
| Granulated sugar | 2.42 teaspoons | 4.85 teaspoons | 198 g |
| Brown sugar, packed | 2.25 teaspoons | 4.51 teaspoons | 213 g |
| Confectioners sugar | 4.25 teaspoons | 8.5 teaspoons | 113 g |
| Butter | 2.12 teaspoons | 4.23 teaspoons | 227 g |
| Long-grain white rice | 2.59 teaspoons | 5.19 teaspoons | 185 g |
| Rolled oats | 5.39 teaspoons | 10.8 teaspoons | 89 g |
| Cocoa powder | 5.65 teaspoons | 11.3 teaspoons | 85 g |
| Honey | 1.41 teaspoons | 2.82 teaspoons | 340 g |
| Water | 2.03 teaspoons | 4.06 teaspoons | 237 g |
Read the row for what you are actually measuring. The spread between the lightest and heaviest row here is wider than any rounding you would ever apply.
10 grams to teaspoons of all-purpose flour
10 grams of all-purpose flour is 4 teaspoons. A cup of it weighs 120 g, so 20 grams comes to 8 teaspoons and half that is 2 teaspoons.
This is the row most bare cup figures came from. Fill it by spoon rather than by dipping, or the cup carries a fifth more than the recipe wanted.
10 grams to teaspoons of granulated sugar
10 grams of granulated sugar is 2.42 teaspoons. A cup of it weighs 198 g, so 20 grams comes to 4.85 teaspoons and half that is 1.21 teaspoons.
Flour at this weight fills 4 teaspoons; this fills 2.42 teaspoons. Swapping them by the cup rather than by the scale moves the batch by the difference.
10 grams to teaspoons of brown sugar, packed
10 grams of brown sugar, packed is 2.25 teaspoons. A cup of it weighs 213 g, so 20 grams comes to 4.51 teaspoons and half that is 1.13 teaspoons.
The same weight of flour comes to 4 teaspoons against 2.25 teaspoons here, and that gap is why the pair needs an ingredient named.
10 grams to teaspoons of confectioners sugar
10 grams of confectioners sugar is 4.25 teaspoons. A cup of it weighs 113 g, so 20 grams comes to 8.5 teaspoons and half that is 2.12 teaspoons.
Beside flour at 4 teaspoons, this row reads 4.25 teaspoons. A cup of it weighs 113 g where flour weighs 120 g.
10 grams to teaspoons of butter
10 grams of butter is 2.12 teaspoons. A cup of it weighs 227 g, so 20 grams comes to 4.23 teaspoons and half that is 1.06 teaspoons.
The same weight of flour comes to 4 teaspoons against 2.12 teaspoons here, and that gap is why the pair needs an ingredient named.
10 grams to teaspoons of long-grain white rice
10 grams of long-grain white rice is 2.59 teaspoons. A cup of it weighs 185 g, so 20 grams comes to 5.19 teaspoons and half that is 1.3 teaspoons.
Beside flour at 4 teaspoons, this row reads 2.59 teaspoons. A cup of it weighs 185 g where flour weighs 120 g.
10 grams to teaspoons of rolled oats
10 grams of rolled oats is 5.39 teaspoons. A cup of it weighs 89 g, so 20 grams comes to 10.8 teaspoons and half that is 2.7 teaspoons.
The same weight of flour comes to 4 teaspoons against 5.39 teaspoons here, and that gap is why the pair needs an ingredient named.
10 grams to teaspoons of cocoa powder
10 grams of cocoa powder is 5.65 teaspoons. A cup of it weighs 85 g, so 20 grams comes to 11.3 teaspoons and half that is 2.82 teaspoons.
Flour at this weight fills 4 teaspoons; this fills 5.65 teaspoons. Swapping them by the cup rather than by the scale moves the batch by the difference.
10 grams to teaspoons of honey
10 grams of honey is 1.41 teaspoons. A cup of it weighs 340 g, so 20 grams comes to 2.82 teaspoons and half that is 0.706 teaspoon.
Flour at this weight fills 4 teaspoons; this fills 1.41 teaspoons. Swapping them by the cup rather than by the scale moves the batch by the difference.
10 grams to teaspoons of water
10 grams of water is 2.03 teaspoons. A cup of it weighs 237 g, so 20 grams comes to 4.06 teaspoons and half that is 1.01 teaspoons.
Flour at this weight fills 4 teaspoons; this fills 2.03 teaspoons. Swapping them by the cup rather than by the scale moves the batch by the difference.
Why there is no single answer
One measures weight and the other measures space, and the bridge between them is how heavy the ingredient is for its bulk. Flour is 120 g to the cup and honey is 340 g — more than double — so the same weight of each fills a very different volume.
A single figure quoted for this pair is a figure for one ingredient with the label left off.
The reverse figure
1 teaspoon of all-purpose flour takes 2 1/2 grams; 1 teaspoon of granulated sugar takes 4.13 grams; 1 teaspoon of butter takes 4.73 grams; 1 teaspoon of honey takes 7.08 grams.
The spread between the lightest and the heaviest of these is the whole reason the question has no single answer.
How to measure this accurately
A cup that has been shaken level is not the same as one swept level with a knife. Shaking settles the contents; sweeping does not.
Weighing is the shortcut here. Tare the bowl to zero, pour, and read the number. No technique to learn and nothing to level off.
When you can round and when you cannot
The test is whether the dish can still be corrected after tasting. If it can, round; if the decision is locked the moment it goes in the oven, do not.
A gram either way is nothing on a roast and everything on a meringue. The dish decides, not the number.
Why grams to teaspoons vary
Grams measure weight. Teaspoons measure volume. That difference is why the answer changes by ingredient. A gram of water fills a different amount of spoon space than a gram of flour, sugar, oil, salt, or cocoa powder.
In the kitchen, this matters most with dry ingredients. Flour can be loose, scooped, sifted, shaken down, or packed into the spoon. Each method changes the amount of air in the spoon, so the same teaspoon can hold different weights.
Sugar behaves differently. Granulated sugar settles more evenly than flour, while confectioners sugar traps more air and clumps easily. Brown sugar is often packed, which pushes out air and makes the spoon heavier than a loose spoonful.
Liquids are more consistent, but not identical. Water, milk, oil, honey, and yoghurt do not share the same density. Thick liquids cling to the spoon, mound slightly, and leave residue behind, so scraping technique can change the practical result.
Small spoon measurements magnify small errors. A little heap, a dip in the centre, or powder stuck to the sides can matter more than expected. This is why baking recipes often prefer grams, especially for flour, cocoa, salt, and leavening.
Use the chart by matching the ingredient first, then multiply from there. Do not use the water line for flour, or the flour line for salt. The spoon result belongs to the ingredient, not to grams in general.
If the ingredient is not listed, choose the closest match by texture and density. Fine dry powders behave more like cocoa or confectioners sugar. Coarse grains behave more like rice or sugar.
Thick sticky ingredients behave more like honey or peanut butter.
For repeatable cooking, weigh the ingredient whenever the recipe gives grams. Use teaspoons mainly for quick seasoning, small additions, or recipes where slight variation will not ruin the result.
A scale removes packing, scooping, and settling from the decision.
If you must use spoons, level dry ingredients with a straight edge unless the recipe says packed or heaped. Stir clumpy powders first. For sticky ingredients, lightly oil the spoon if the recipe allows it, then scrape it clean.
Cup references can also mislead because cup standards differ. A US customary cup, a metric cup, and a UK legal cup are not the same size. That difference sits on top of the density issue, so grams remain the safer base.
Gram to teaspoon formula
Use this formula: teaspoons = grams × the ingredient’s teaspoon-per-gram factor. Take the gram weight from your recipe, find the matching ingredient in the chart, then multiply. The result is the volume you would measure with a teaspoon.
The ingredient factor is the important part. Grams measure weight, while teaspoons measure volume. A gram of honey takes up less spoon space than a gram of cocoa powder, because honey is denser.
The same gram weight can fill very different amounts of a spoon.
For a quick example, use water and cocoa powder. Multiply the recipe’s gram amount by the water factor for water, or by the cocoa powder factor for cocoa powder. Do not use the water result for cocoa powder. The spoon amount will be wrong.
If the chart gives a general conversion, treat it as a fallback only. It may be close enough for loose estimating, but it is not a reliable baking conversion. Use the named ingredient whenever the ingredient appears in the chart.
For all-purpose flour and dry dog kibble, the chart uses the same factor: 0.4. That does not mean all dry ingredients behave alike. It means those two listed items share the same spoon conversion in this reference.
For honey, the factor is 0.141. That lower value tells you the same gram weight needs fewer teaspoons than many dry ingredients. Sticky, heavy ingredients pack more weight into the same spoon space.
Measure the gram amount first if accuracy matters. A kitchen scale removes the guesswork from scooping, settling and packing. Then use the formula to translate that weight into teaspoons only when you need a spoon measure.
Use level teaspoons unless the recipe says otherwise. Heaped spoons change the volume and defeat the conversion. Packed ingredients, such as packed brown sugar, need the packed entry because packing changes how much weight fits into the spoon.
For powders, stir or loosen the ingredient before spooning if it has settled hard in the container. Settled flour, cocoa powder or confectioners sugar can make a spoon heavier than expected.
The formula assumes the chart’s stated ingredient behaviour, not a compressed scoop.
If your ingredient is not in the chart, choose the closest match only for rough kitchen work. Do not use a guess for baking formulas, nutrition tracking or pet feeding.
In those cases, weigh the ingredient or find a tested conversion for that exact product.
Ingredient density changes the result
Ingredient density changes the result because a gram measures weight, while a teaspoon measures space. Dense ingredients take up less spoon space for the same weight. Light, fluffy ingredients take up more.
That is why the chart must be ingredient-specific.
A cook sees this most clearly with powders. Cocoa powder, confectioners sugar, flour, and ground coffee can all look similar in a spoon, but they do not pack into that spoon the same way.
Swapping one conversion for another changes the amount in the bowl.
Scooping also changes density. Flour dipped straight from the bag is usually more compact than flour spooned lightly into a measure. Brown sugar is often packed on purpose. Cocoa powder may be clumpy.
These handling differences change how much weight fits in the same teaspoon.
Liquids have their own differences. Water, milk, oil, honey, and yoghurt do not weigh the same by volume. Honey is heavy and slow to level. Oil coats the spoon. Yoghurt can mound above the rim unless it is levelled.
Small spoon amounts make these differences more noticeable. A slight mound, air pocket, or packed spoon can shift the result.
For salt, coffee, baking powder-style ingredients, and spices, that small shift can affect flavour, bitterness, texture, or rise.
Use the chart ingredient name that matches what you are measuring. Choose packed brown sugar only for packed brown sugar. Choose confectioners sugar for icing sugar, not granulated sugar.
Choose rolled oats for oats, not flour, even if both are dry pantry ingredients.
If the ingredient is not listed, use the closest match only for low-stakes cooking. That can work for a sauce, topping, or casual mixture. It is a poor choice for baking, curing, strong seasoning, or anything where the ingredient controls structure.
For baking, weigh the ingredient if the recipe gives grams. A scale removes the density problem. The teaspoon conversion is most useful when a scale is not available, the amount is small, or the recipe needs a quick practical estimate.
Level dry ingredients unless the recipe says packed or heaped. Stir or loosen powders before measuring if they have settled. Scrape sticky ingredients cleanly from the spoon. Use the same method each time so the conversion behaves consistently.
The main rule is simple: grams do not turn into teaspoons until the ingredient is known. Identify the ingredient, match it to the chart, then measure in a way that matches the recipe wording.
Using the conversion safely
Use the chart as an estimate, not as a substitute for a scale when precision matters. Teaspoons measure volume, so the result changes with packing, settling, chopping, grinding, and moisture.
A gram reading is stable; a spoonful is shaped by handling.
Choose the ingredient name that matches the food in front of you. Packed brown sugar is not the same as loose brown sugar. Cocoa powder is not the same as chocolate chips. Rolled oats are not the same as ground oats.
If the ingredient is listed, use that entry rather than the generic line. The generic value is only a fallback for rough kitchen work. It can be misleading for dense liquids, fluffy powders, coarse grains, and sticky spreads.
Level the teaspoon unless the recipe says otherwise. A heaped spoon can hold much more than a level spoon, especially with flour, cocoa, confectioners sugar, coffee, and oats. Scrape the top flat with a straight edge for a cleaner measure.
Do not scoop directly from a compacted bag if accuracy matters. Flour, sugar, cocoa, and salt settle during storage. Stir or loosen the ingredient first, then spoon it into the measuring spoon and level it.
For sticky ingredients, lightly coat the spoon if the recipe allows it, then fill and level as consistently as possible. Honey, peanut butter, cream cheese, and yoghurt cling to the spoon, so some of the measured amount may stay behind.
For liquids, use a measuring spoon set on a steady surface. Fill to the rim without doming or spilling. Water, milk, and oil are easier than thick liquids, but surface tension can still change the amount in a small spoon.
Use teaspoons only for small amounts. As the amount grows, small spoon errors add up. If a recipe depends on structure, texture, or food safety, weigh the ingredient instead of building the amount from repeated teaspoons.
Be especially careful with salt, leavening, caffeine, pet food, and concentrated flavourings. A small volume error can change taste, texture, or suitability. For dry dog kibble, use the package feeding guide and a scale when portions matter.
Keep the same method through the whole recipe. Do not switch between scooped, packed, shaken, and levelled measures. Consistency will not make teaspoons as precise as grams, but it reduces avoidable variation.
If the result looks wrong, trust the ingredient. A powder that has clumped, a spread that is cold, or sugar that has hardened will not behave like the chart. Break up lumps, soften as needed, or weigh it.
For repeat baking, write down the ingredient, brand, and measuring method that worked. The next batch will be easier to match, because the practical conversion is tied to that ingredient and how you handled it.
