How it is computed
Grams = cups × the weight of one cup of that sugar, as published by King Arthur Baking. Brown sugar is packed firmly into the cup; powdered sugar is spooned in unsifted and levelled.
FAQ
Why is powdered sugar so much lighter?+
Its fine particles trap air, so a cup holds far less sugar by weight than granulated.
Can I swap honey for sugar cup for cup?+
Not directly: honey is heavier, sweeter and adds liquid. A common rule is about ¾ cup honey per cup of sugar, with a little less liquid elsewhere.
