How to Convert Cups to Grams
Cups measure volume, while grams measure weight. Because different ingredients have different densities, one cup of flour weighs far less than one cup of honey. To convert accurately you need the grams-per-cup value for the specific ingredient.
grams = cups × grams per cup
Grams per Cup Reference
These are the standard US-cup reference values this converter uses for each ingredient:
- All-purpose flour: 125 g per cup
- Granulated sugar: 200 g per cup
- Brown sugar (packed): 220 g per cup
- Butter: 227 g per cup
- Water: 237 g per cup
- Milk: 244 g per cup
- Honey: 340 g per cup
- Rice (uncooked): 185 g per cup
- Rolled oats: 90 g per cup
- Cocoa powder: 100 g per cup
Why Weighing Is More Accurate
Measuring by cups can be inconsistent, especially for dry ingredients. How firmly you scoop and pack flour can change its weight by 20% or more, which is enough to affect the texture of baked goods.
- Consistency: A kitchen scale gives the same result every time, regardless of how you scoop.
- Precision: Grams allow finer adjustments than fractions of a cup.
- Less cleanup: Weigh ingredients straight into one bowl instead of dirtying multiple measuring cups.
Note: These conversions use standard US-cup reference values and approximate ingredient densities. Actual weights vary with brand, humidity, and how the ingredient is packed. For best results in baking, weigh ingredients with a kitchen scale.
