Why Accurate Baking Measurements Matter

Baking is chemistry. Too much flour makes bread dense. Too little sugar prevents browning. A kitchen scale gives you the precision that cups can't — but when you're converting a recipe from cups, you need to know the exact density of each ingredient.

This page lists every common baking ingredient with its verified cups-to-grams conversion. Each converter accounts for different measurement methods (spooned vs scooped) and cup standards (US, metric, imperial).

Flour Conversions

All-purpose flour is the most commonly measured ingredient and also the most inconsistently measured. Depending on how you fill the cup, 1 cup can weigh anywhere from 110g (sifted) to 160g (scooped). Our converters default to the spooned-and-leveled method (120g per cup) as recommended by King Arthur Baking.

Sugar Conversions

Granulated sugar packs consistently, so it's more forgiving than flour. Brown sugar is typically packed, which is why 1 cup weighs 220g rather than 200g. Powdered sugar is lighter at 120g per cup because it contains cornstarch and has more air.
