Kitchen measurement answers

Why cups and grams don't convert one way

Grams measure weight; cups measure volume. A cup of flour weighs about half as much as a cup of water, because flour is full of air. That is why every grams-to-cups answer here starts with the ingredient.

How you fill the cup matters as much as the ingredient. All weights here assume dry ingredients are spooned into the cup and levelled, which is what most American recipes mean. Scooping straight from the bag packs flour down and can add 15 to 20 percent. Brown sugar and butter are packed, and liquids are read at eye level in a jug.

The weights come from USDA FoodData Central, the US government's food database. Every ingredient page also shows the figure from King Arthur Baking's chart, so you can see where bakers disagree and why.
