Measuring tips

Weigh in grams on a kitchen scale for the most accurate result, and set the scale to zero (tare) with the bowl on it.
This site uses the US cup of 236.6 ml. A metric cup is 250 ml, so recipes from the UK, Australia or New Zealand can differ.
Check whether the recipe means the ingredient sifted, packed, melted or cooked, because that changes the weight per cup.
