Common questions
Is a cup the same for dry and liquid ingredients?
A cup is the same volume either way, but dry ingredients pack differently. A cup of flour can weigh noticeably different amounts depending on how it is scooped, so weighing in grams is more reliable.
How many cups are in a liter?
About 4.23 US cups.
Is a cup 250 mL?
Not for the US cup, which is about 236.6 mL. A 250 mL metric cup is used in some countries, including Australia.
