Frequently Asked Questions

Is a US gallon the same as a UK gallon?

No. A US liquid gallon is 3.785 litres and an imperial gallon is 4.546 litres — 20% larger. The same ratio applies to pints, quarts and fluid ounces, which is why recipes fail when the system is assumed.

How many millilitres in a cup?

236.59 ml for a US cup. A metric cup is exactly 250 ml, and an imperial cup was 284 ml. Modern UK recipes generally use grams instead, which avoids the problem entirely.

How many tablespoons in a cup?

16 US tablespoons, each of 14.79 ml. Australian tablespoons are 20 ml — four teaspoons rather than three — which throws out baking recipes noticeably.

Why do dry and liquid measures differ?

Because volume does not fix mass. A cup of flour can vary by 20% depending on how it is packed. Weighing dry ingredients is far more reliable, which is why professional recipes use grams.
