Cups to Grams for Common Ingredients

Because a cup measures volume, the gram weight changes with each ingredient. Look yours up below to convert cups into grams accurately.

Cups to Grams: The Essential Kitchen Conversion

American recipes use cups while most international recipes use grams. This converter bridges the gap with ingredient-specific accuracy. Unlike a simple mathematical conversion, cups-to-grams requires knowing each ingredient density. A cup of water weighs 237g, a cup of flour weighs 125g, and a cup of honey weighs 340g. All very different despite being the same volume.

Why Professional Bakers Prefer Grams Over Cups

Cup measurements can vary by 20% or more depending on how you scoop the ingredient. Packed flour weighs significantly more than sifted flour per cup. This inconsistency is why professional bakers worldwide measure by weight. Converting your favorite cup-based recipes to grams ensures consistent results every single time.
