Weigh it if you can

Volume measures are convenient but imprecise — the same cup can hold noticeably different amounts depending on how the ingredient is packed, how humid the room is, and whether it was sifted. A digital kitchen scale removes the variable entirely, which is why professional and European recipes give weights. If you bake regularly, a scale is the cheapest accuracy upgrade available.

Frequently asked questions

How many grams is 4 cups of uncooked white rice?

About 740 grams, or 26.1 ounces.

How many grams in a cup of uncooked white rice?

Roughly 185 grams per US cup.

Is a US cup the same as a metric cup?

No. A US customary cup is 236.6 ml; a metric cup — used in Australia, New Zealand and much of Europe — is 250 ml, about 6% larger. An imperial cup, still seen in older British recipes, is 284 ml. For a cup of uncooked white rice that is a difference of roughly 10.5 g between US and metric.

Should I sift before or after measuring?

It matters, and recipes are often ambiguous. "1 cup sifted flour" means sift first, then measure — which gives less flour than "1 cup flour, sifted", where you measure first. When in doubt, weigh.
