Cups of Flour to Grams Converter
This page converts cups of all-purpose flour into grams, the way serious bakers weigh ingredients. One US cup of all-purpose flour is about 125 g, so the conversion is a multiplication by 125. Because all-purpose flour is measured by volume in many American recipes but by weight in most European and professional ones, a quick, reliable conversion saves failed bakes.
How to convert Cups of flour to grams
Multiply the number of cups by 125. For example 0.5 cups of all-purpose flour is 0.5 × 125 = 62.5 g. To go the other way, divide grams by 125: 62.5 g ÷ 125 = 0.5 cups.

How much does a cup really weigh?
Density is the reason there is no single answer: a cup is a measure of space, not weight, so its weight depends on the ingredient. Flour compacts when scooped, so one cup can weigh anywhere from 120 g (spooned and leveled) to 150 g (scooped straight from the bag). Many American baking sites use 120 to 125 g. The figure of 125 g per cup used here is a common baking reference value; your own flour, humidity and scooping habit can move it a few percent either way.
Measure by spooning the ingredient lightly into the cup and leveling the top with a knife; never press it down unless the recipe says "packed". Scooping straight from the bag compacts dry ingredients and can add 20% or more. A digital kitchen scale removes the guesswork entirely, and it also means fewer dishes to wash.
Cups of flour to grams FAQ
How many grams are in one cup of all-purpose flour?
One US cup of all-purpose flour weighs about 125 g. That is a typical reference value, not an exact constant, because the weight changes with how the ingredient is packed.
What is the quickest way to convert cups of all-purpose flour and grams in my head?
Round the factor to about 120 g per cup: 0.5 cups is then about 60 g against an exact 62.5 g.
Why do recipes disagree about the weight of a cup of all-purpose flour?
Brands, sifting and scooping style change how much fits in the cup. Flour compacts when scooped, so one cup can weigh anywhere from 120 g (spooned and leveled) to 150 g (scooped straight from the bag). Many American baking sites use 120 to 125 g.
Should I weigh all-purpose flour instead of using cups?
Yes, if you can. Weight is repeatable, so a recipe that calls for 250 g of all-purpose flour will give the same result every time, while two cups can differ by 10 to 20% from one person to the next.
