How to Convert Grams to Cups Without a Scale: The Complete Guide
If you've ever followed a recipe from a European cookbook or website, you've almost certainly come across measurements in grams instead of cups. While grams are more precise, most American home bakers measure by volume using cups and tablespoons. So what do you do when a recipe calls for 200 grams of flour and all you have is a measuring cup?
This guide explains exactly how to convert grams to cups for the most common baking ingredients — and shows you the fastest way to do it using our free grams to cups converter.
Why Grams and Cups Are Different
A cup is a unit of volume — it measures how much space something takes up. A gram is a unit of weight — it measures how heavy something is. Different ingredients have very different densities, so you cannot use a single conversion factor.
- 1 cup of all-purpose flour = about 125 grams
- 1 cup of granulated sugar = about 200 grams
- 1 cup of butter = about 227 grams

The Manual Formula
Cups = Grams ÷ Grams-per-Cup for that ingredient
Example: 150g flour ÷ 125 (g per cup) = 1.2 cups. Browse our baking ingredients section for the grams-per-cup value of every ingredient.
Measuring Flour Correctly
A packed cup of flour weighs 150-200g — but should weigh 120-125g. Always spoon flour into the cup and level off with a straight edge. Never scoop directly from the bag.
