Where this goes wrong across borders
A US cup is 236.6 ml. A metric cup, used in Australia and New Zealand, is 250 ml — 5.7 per cent more. An old UK imperial cup is 284 ml. Measured in the metric cup the 1 liter figure above would read 4.47 cups instead of 4.23 cups.
How to read the chart
Find your amount in the left column and read across. Amounts between two rows scale in a straight line, so half way between two rows is half way between the two answers.
What moves this number
Nothing about the ingredient. The only way to get a different answer is to be working in a different system than you think you are.
Going the other way: cups to liters
| Cups | Liters |
|---|---|
| 1/4 cup | 0.059 L |
| 1/2 cup | 0.118 L |
| 1 cup | 0.237 L |
A few rows are enough to place it; the direction has its own page with the amounts filled in.
Measuring it without getting it wrong
Read a liquid measure at eye level with the cup on the counter. Held up and read from above, the curve of the surface makes it look fuller than it is.
How much rounding this will take
A convenient number costs little on a single quantity and adds up quickly once a recipe is doubled or tripled. Round late, not early.
Where this usually goes wrong
Reading a liquid measure from above. Lift the jug to eye level and the surface curves; the figure read off is consistently more than the jug holds.
Where this comes up
Older cookbooks and handwritten family recipes rarely state which system they meant. 1 liter is 4.23 cups is the assumption that makes most of them work.
Halving and doubling
Half of 1 liter is 2.11 cups. Double it and you have 8.45 cups; triple it and you are at 12.7 cups. A batch cut to a quarter needs 1.06 cups.
The relationship is a straight multiple all the way through, so any factor scales the same way.
How much precision this needs
The exact figure for 1 liter is 4.23. Written the way most cooks would write it, 4 cups, it is out by 0.227 — about 5.4 per cent. On one batch that is invisible.
Scaled four times the gap is 0.907, which is where it starts to show in anything that has to set.
