Plain Flour Measurement Converter
Use the tool below to convert plain flour from the measurements in your recipe to the measurements that you need.
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.

Frequently Asked Questions
- Are plain flour and All-Purpose Flour the same thing?
- Yes. All-Purpose Flour is another name for plain flour, so they are the same ingredient and measure identically. A cup of plain flour weighs 140 grams under either name, and every conversion on this page holds whichever name your recipe uses. Recipes swap the two freely, so you can follow either 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.
- What is 0.25 cups of plain flour in tablespoons?
- 0.25 cups of plain flour is 4.17 tablespoons. This is the same for any ingredient, since cups and tablespoons are both volume units and do not depend on what you are measuring. One cup is about 16.67 tablespoons, so 0.5 cups is 8.33 tablespoons. Use the volume converter to switch between cups, tablespoons, teaspoons, and millilitres for any amount. Open the volume converter
- How much does a cup of plain flour weigh?
- 1 cup of plain flour in grams is 140 grams. The ratio is fixed, so 2 cups is 280 grams and half a cup is 70 grams. Weighing plain flour by the cup is the most common way to measure it for baking. See the full cup to grams chart for plain flour, or use the converter on this page for any other amount. 1 cup plain flour in grams

Related to Plain Flour
Bread Flour
A straight swap with more protein (150 g vs 140 g per cup), so gluten develops further and the crumb turns chewier. Good in pizza, bagels, and rustic loaves; in delicate cakes it can read tough, so reserve it for bakes that want structure. See our Bread Flour converter.
Cake Flour
The tender-crumb swap: cake flour is softer and lower in protein, 7 to 9% against 10 to 12%, giving a finer, lighter result in sponges and cupcakes (130 g vs 140 g per cup). Avoid it for bread and pizza, where the weaker gluten leaves the dough slack. No cake flour on hand? Take 2 tablespoons out of a cup of plain flour and replace them with cornstarch. See our Cake Flour converter.
Brown Sugar
Brown sugar is pressed into its cup while plain flour is spooned in and levelled, which is how one ends up at 220 g and the other at 140 g. Reading a cookie recipe as if both cups were filled the same way is the usual reason the dough turns out wet or sandy. See our Brown Sugar converter.
Self Raising Flour
Self-raising flour is plain flour with baking powder already blended in, matched in weight per cup (140 g each). Use the self-raising flour calculator to make your own from plain flour, or swap to plain flour and add your own leavener. See our Self Raising Flour converter.
