Cups to Grams Converter
Cups measure volume and grams measure weight, so the conversion depends on the ingredient. Use the live converter for volume (cups ↔ litres/ml), and the chart below for common baking ingredients by weight.

How to convert cups to grams
There is no single cups-to-grams number — 1 cup of flour weighs far less than 1 cup of honey because their densities differ. Always convert per ingredient using a trusted table (below) or a kitchen scale for best accuracy.
Values below assume a US cup (236.6 ml). Flour is spooned-and-leveled; packing it down can add 20% or more. When precision matters in baking, weigh in grams.
Cups to grams by ingredient (1 US cup)
| Ingredient | 1 cup | ½ cup |
|---|---|---|
| All-purpose flour | 120–130 g | 60–65 g |
| Bread flour | 120–130 g | 60–65 g |
| Granulated sugar | 200 g | 100 g |
| Powdered sugar | 120 g | 60 g |
| Butter | 227 g | 113 g |
| Rolled oats | 90 g | 45 g |
| Cocoa powder | 85 g | 43 g |
| Honey | 340 g | 170 g |
| Milk | 245 g | 123 g |
Frequently asked questions
- How many grams is 1 cup of flour?
- About 120–130 g for all-purpose flour, spooned and leveled. Packed flour weighs more.
- How many grams is 1 cup of sugar?
- About 200 g for granulated sugar; powdered sugar is lighter at ~120 g per cup.
- Why isn't there one cups-to-grams ratio?
- Cups measure volume and grams measure weight. Each ingredient has a different density, so the gram weight of one cup varies by ingredient.
