The Ultimate Grams to Cups Conversion Chart
A practical reference guide to grams to cups conversions for common baking and cooking ingredients, with notes on why density changes by ingredient.
Why There Is No Single Formula
In cooking and baking, one of the most frustrating obstacles is discovering a recipe written in a measurement system different from your kitchen equipment. If you own measuring cups and your recipe asks for 200 grams of flour, you cannot simply look up a universal "grams to cups" conversion number.
Grams measure weight (mass), while cups measure volume.
Because different ingredients possess vastly different densities, one cup of each ingredient weighs a very different amount:
- 1 cup of Water: ~236.6 grams
- 1 cup of Granulated Sugar: 200 grams
- 1 cup of All-Purpose Flour: 125 grams
- 1 cup of Rolled Oats: 90 grams
- 1 cup of Honey: 340 grams
If you attempted to use a single ratio for all of these, your dough would be either dry like cardboard or liquid like soup!

3 Essential Rules for Measuring by Cup
- The Spoon and Level Method for Flour: Never scoop flour straight out of the bag with your measuring cup. The cup acts like a compacting shovel and can pack up to 150g of flour into a cup intended for 125g. Instead, fluff the flour with a fork, spoon it into the measuring cup until overflowing, and sweep the excess level with the straight back of a butter knife.
- Brown Sugar Must Be Packed (Unless Stated Otherwise): Brown sugar crystals are coated in sticky molasses that creates air pockets unless pressed down. Press it into the cup until it holds its shape when inverted.
- Use Liquid Measuring Cups for Liquids: Dry measuring cups are meant to be leveled flush at the top rim. Liquid measuring cups have a pour spout and clear markings below the rim so liquids do not spill when transported to the mixing bowl.
