About Cups & Grams
Cups & Grams is a free, independent reference for cooking and baking conversions. It exists to answer one deceptively simple question accurately: how much does this ingredient actually weigh?
A measuring cup tells you volume, not weight — and a cup of flour, a cup of sugar and a cup of honey are wildly different weights. Most generic converters ignore that. Every converter here uses the real density of the specific ingredient, so the numbers you get are the numbers you can trust.

Who's behind Cups & Grams
It's edited by Lou Lohman. We are not a test kitchen and we don't pretend to be — we are focused on getting reference data right. Every figure is compiled and cross-referenced against established sources, chiefly the King Arthur Baking Ingredient Weight Chart and the USDA FoodData Central database, and checked for internal consistency before it is published. Where sources disagree, we use a sensible typical value and say so on our methodology page.
If a figure looks wrong, tell us. We read every report and update when a correction holds up.
