Grams to Cups Converter
Convert grams to cups using ingredient density. Default density is for all-purpose flour.
The Grams to Cups Converter converts weight in grams to volume in cups based on the density of the ingredient. Different ingredients have very different densities, so this conversion depends on what you are measuring.
Enter the weight in grams and the density factor (grams per cup). Common density factors: all-purpose flour = 125 g/cup, granulated sugar = 200 g/cup, butter = 227 g/cup, water = 237 g/cup, rice = 185 g/cup.
Baking by weight (grams) is more accurate than measuring by volume (cups) because cup measurements can vary based on how the ingredient is packed. This converter helps bridge recipes between the two systems.
Frequently Asked Questions
Why does the density factor matter?
Different ingredients weigh different amounts per cup. 1 cup of flour (~125g) weighs much less than 1 cup of sugar (~200g) or butter (~227g).
What is the density factor for sugar?
Granulated sugar is about 200 g/cup, brown sugar is about 220 g/cup (packed), and powdered sugar is about 120 g/cup.
Is weighing more accurate than measuring by cups?
Yes. A cup of flour can vary from 120-160g depending on how it is scooped. Weighing eliminates this variability for more consistent results.
