Measurement FAQ
Everything you need to know about converting cooking measurements accurately.
One US cup of all-purpose flour weighs approximately 120 to 125 grams. A metric (UK) cup of flour weighs about 132 grams. For baking accuracy, weighing ingredients in grams is highly recommended.
A US customary cup is 236.59 ml, while a UK (metric) cup is exactly 250 ml. This small difference can affect baking recipes, so it is important to know which standard your recipe uses.
To convert millilitres to US fluid ounces, divide the ml value by 29.57. For UK (imperial) fluid ounces, divide by 28.41. For quick mental math, 30 ml is roughly equal to 1 US fluid ounce.
Volume-to-weight conversions (like cups to grams) depend entirely on the density of the ingredient. For example, 1 cup of water weighs 236g, but 1 cup of flour weighs only 120g, and 1 cup of honey weighs about 340g.
