About the Kilograms to Cups — Cake Flour
Cake flour is milled finer and is usually sifted before measuring, which is why a cup weighs noticeably less than plain flour. If a recipe says "1 cup sifted cake flour" it means sift first, then measure — the reverse order gives a heavier cup and a denser cake. Low protein, around 7–9%, which is what keeps the crumb tender. The figure this page works from is 114 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database.

The maths behind it
This tool uses us cup = kilogram × 8.7719298246, derived from cake flour weighing 114 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
Cake flour is milled finer and is usually sifted before measuring, which is why a cup weighs noticeably less than plain flour. If a recipe says "1 cup sifted cake flour" it means sift first, then measure — the reverse order gives a heavier cup and a denser cake.
Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Frequently asked questions
Can I make cake flour from plain flour?
Roughly. Remove two tablespoons from a cup of all-purpose flour and replace them with two tablespoons of cornflour, then sift several times. It is a decent approximation for most recipes, though it will not match a true low-protein flour exactly.
Why does a cup of cake flour not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. Cake flour has its own density — 114 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
More than for plain flour, because cake flour is milled finer and settles harder. It is also usually sifted, and sifting before measuring rather than after changes the cup by 10–15 g. Cake recipes are the least forgiving of an over-measured cup, which is why a scale earns its place fastest here.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.
