How many cups is 100g of flour?

100g of plain flour (all-purpose) is approximately 0.83 cups, or just under a cup. For precise baking, always weigh ingredients rather than converting back to cups — a kitchen scale gives far more accurate results.

How many cups is 250g of flour?

250g of plain flour is approximately 2.08 cups. However, cup measurements vary significantly depending on how the flour is packed, so weighing is always more accurate.

How many cups is 200g of sugar?

200g of caster or granulated sugar is exactly 1 cup. This is one of the more reliable cup conversions because sugar packs consistently.

How many cups is 100g of butter?

100g of butter is approximately 0.44 cups, or just under half a cup. In American recipes, butter is usually measured in sticks — 100g is just under 1 stick (113g).

Why should I convert grams to cups?

Most of the time you shouldn't — grams are more accurate. But if you're following an American recipe that uses cups, or using a measuring tool that only shows cups, this converter helps you work backwards from a weight you know.

How many cups is 125g of butter?

125g of butter is approximately 0.55 cups, or a little over half a cup. In American terms, it's just over 1 stick of butter (1 stick = 113g).

How many cups is 150g of flour?

150g of plain flour is approximately 1.25 cups, or 1 cup and 4 tablespoons. Note that a scooped cup of flour often weighs 150g — which is why spooning and levelling matters.

How many cups is 500g of flour?

500g of plain flour is approximately 4.17 cups, or just over 4 cups. At this quantity, weighing is strongly recommended over cup measurements.

Why Grams Are Better Than Cups

You're already using grams — here's why that's the right call, and when cup conversions actually make sense.

⚖️
Grams Are Always Accurate
A gram is a gram. A cup of flour can be anywhere from 120g to 160g depending on how it's filled. If you're baking anything that needs to rise, weigh it. Cups are fine for liquids and rough cooking. Not for baking.

🍽️

When Cup Conversions Are Useful

You're following an American recipe and want to sanity-check a measurement. You're using a US app or tool that outputs cups. You're teaching someone who only has measuring cups. These are legitimate use cases — that's why this page exists.

🔄

The One-Way Conversion Problem

Converting grams to cups introduces imprecision that wasn't there. If a recipe was developed in grams, converting to cups and back to grams gives you a different number. Stay in grams end-to-end when the original recipe uses them.
