About Grams Per Cup

Grams Per Cup is a free cooking converter built to solve one specific, everyday problem: recipes written in cups when you have a kitchen scale, or written in grams when you only have measuring cups. Because a cup measures volume and grams measure weight, there is no single conversion that works for every ingredient — so this site stores the real density of each ingredient and converts accordingly.

The conversion values are common, widely-used kitchen approximations based on the US cup (about 236.6 ml). They are meant as practical cooking guides. Density varies with brand, humidity, and how an ingredient is packed or sifted, so treat the numbers as close estimates rather than laboratory measurements. When precision matters, weighing on a scale is always the most reliable method.
