Plain flour (also known as all-purpose flour) is one of the most commonly used ingredients in baking and cooking. It has a moderate protein content, making it versatile enough for pastries, breads, sauces, and coatings. In the UK, Australia, and New Zealand, it’s called plain flour, while in the US and Canada, it’s known as all-purpose flour.

Since different countries use different measurement systems (and flour can settle when scooped), converting between grams, cups, and tablespoons helps ensure your recipes turn out just right. Use this page to easily convert plain flour for any recipe.

Recipes use the two names interchangeably, so you can follow either one without changing quantities or weighing any differently.
Why does a cup of flour vary in weight?
Flour compresses easily, so how you fill the cup changes the weight. Spooned lightly and levelled, a metric cup of plain flour is about 140 grams. Sifted first it can fall to around 125 grams, while scooping straight from the bag and packing it down can push it to 160 grams. For consistent baking, weigh flour on a scale rather than measuring by cup.
