How many grams is 1 cup of flour?

One US cup (240ml) of plain or self-raising flour weighs approximately 125g. This is based on the spoon-and-sweep method. If you scoop flour directly from the bag, it may weigh up to 140-150g due to compression.

Why does the result show fractions?

Cup measurements in recipes are typically expressed as fractions (1/4, 1/3, 1/2, 3/4). The converter detects when your gram amount is close to a standard cup fraction and shows it in that familiar format.

Can I convert any ingredient?

The converter includes the most common baking and cooking ingredients. For unlisted ingredients, you can use the Cooking Weight to Volume Converter which has a broader range of items and density data.

Are these US cups or metric cups?

These are US cups (240ml). The Australian metric cup is 250ml — use our Australian to UK Cups Converter for that. There is no standard UK cup measurement, which is why UK recipes typically use grams.

How do I convert grams to cups for a recipe?

Divide the weight in grams by the grams-per-cup value for your specific ingredient. For example, 250g of plain flour divided by 125g per cup equals 2 cups. Always use ingredient-specific conversions rather than a generic cups-to-grams ratio, as each ingredient has a different density.

How We Calculate This

The converter divides your gram amount by the grams-per-cup value for each ingredient. Different ingredients have different densities, so the conversion factor varies.

The Formula

Cups = Grams / Grams per cup
Tablespoons = Cups x 16

Quick Reference

125g plain flour = 1 cup
200g caster sugar = 1 cup
227g butter = 1 cup
90g rolled oats = 1 cup
