Cups to Grams: Baking Conversion Chart for Flour, Sugar, Butter and More
How many grams are in a cup of flour, sugar, butter, oats or rice? A clear conversion chart, plus why weighing gives better baking.
- 1 cup of all-purpose flour is about 120 g (spooned and leveled)
- 1 cup of granulated sugar is about 200 g; 1 cup of butter is 227 g
- A US cup is 236.6 ml; a metric cup is 250 ml
A cup is a measure of volume, a gram is a measure of weight, and different ingredients weigh very different amounts. A cup of flour weighs a lot less than a cup of sugar. Here is a clear chart for the ingredients you use most, plus an easy way to convert any amount with our free cups to grams converter.

Why weighing is more accurate
If you scoop flour straight from the bag with the cup, you pack it down and can end up with 140 to 150 g instead of 120 g. That extra flour is the most common reason for dry cakes and dense cookies. A digital kitchen scale removes the guesswork and means fewer bowls to wash.
US cups, metric cups and tablespoons
- US cup: 236.6 ml (often rounded to 240 ml).
- Metric cup (Australia, New Zealand, Canada and others): 250 ml.
- Tablespoon: about 15 ml in the US and UK. In Australia a tablespoon is 20 ml.
- Teaspoon: about 5 ml.
- 1 cup = 16 tablespoons = 48 teaspoons.
- 1 US stick of butter = 1/2 cup = 113 g.
How to measure flour without a scale
- Fluff the flour in the bag with a spoon.
- Spoon it into the measuring cup until it overflows.
- Level it off with the back of a knife. Do not tap or press.
