How many grams of flour are in one cup?

One US cup of all-purpose (plain) flour weighs about 125 g. Bread flour is roughly 130 g, cake flour about 115 g and wholewheat about 120 g per cup.

Why does the type of flour matter?

Different flours have different densities, so a cup of cake flour weighs less than a cup of bread flour. Choosing the right type gives a more accurate conversion.

How many cups is 250g of flour?

For all-purpose flour at 125 g per cup, 250 g is exactly 2 cups. For bread flour (130 g/cup) it is about 1.9 cups, and for cake flour (115 g/cup) about 2.2 cups.

Is plain flour the same as all-purpose flour?

Yes. Plain flour (UK) and all-purpose flour (US) are the same thing, weighing about 125 g per US cup in this converter.

Should I scoop or spoon flour into the cup?

Spoon flour into the cup and level it off with a knife. Scooping packs it down and can add 20-30% more flour, which is why weighing in grams is more reliable for baking.

Why is weighing flour more accurate than cups?

A cup measures volume, which varies with how packed the flour is, while grams measure mass directly. Weighing removes that variability, giving consistent results batch to batch.

Grams to Cups (Flour) Converter

This converter changes flour between grams and US cups for the four most common types — all-purpose (plain), bread (strong), cake (sponge) and wholewheat. Because each flour packs to a different density, it lets you pick the type for accurate baking, in either direction.

How it works

Each flour type has a fixed weight per US cup baked into the tool. Conversion is a single multiply or divide:

Grams → cups: cups = grams ÷ (grams per cup)
Cups → grams: grams = cups × (grams per cup)

The per-cup weights used are:

Flour type	Grams per US cup
All-purpose / plain	125 g
Bread / strong	130 g
Cake / sponge	115 g
Wholewheat	120 g

Example

You have 250 g of all-purpose flour and want cups:

250 ÷ 125 = 2 cups

The same 250 g of cake flour (115 g/cup) would be about 2.17 cups, showing why choosing the right type matters.

Spoon flour into the cup and level it off rather than scooping for the closest match. The whole conversion runs locally in your browser — nothing is uploaded.
