Cups to Grams of Butter Converter (cup to g)

In the US, butter is sold in quarter-pound sticks with tablespoon lines printed on the wrapper, and recipes ask for it in cups, sticks or tablespoons. The cup figure follows from the package: two sticks make a cup, so this converter treats 1 cup of butter as half a pound, which is exactly 226.796185 g because the pound is defined as 0.45359237 kg. USDA rounds the same amount to 227 g.

Because the cup amount comes from package markings rather than from spooning, butter converts more dependably than flour or sugar: cutting a stick at its printed lines gives much the same weight every time. The figure assumes ordinary solid butter. Whipped butter has air beaten into it and spreads have a different makeup, so for those, go by the weight on the label or use a scale.

How to use this tool

1. Type a value in the Cup box to see it in grams of butter, or type in the Gram of Butter box to convert the other way.
2. Press ⇄ to swap the two units, or Load example for a typical value.
3. Check the charts below for common values; for other units, open the Cooking Measure converter.

Formula

grams of butter = cups × 226.796185 (1 cup = ½ lb)

cups = grams of butter ÷ 226.796185 (1 cup = ½ lb)

Both factors come from the converter's own definitions: 1 gram of butter = 0.0044092452437 cups and 1 cup = 226.796185 grams of butter (shown to 12 significant digits).

Example

Two conversions worked with the same factors the converter uses:

0.75 cup ≈ 170.097 g butter

250 g butter ≈ 1.10231 cup

Butter amounts in classic US recipes

Quick mental estimate

Picture sticks: each half cup is one stick of about 113 g, so ¾ cup → 1½ sticks → 113 + 57 = 170 g. The exact figure is 170.1 g, so rounding the stick to 113 g leaves you about 0.1 g low.

Use the converter or the charts when the exact figure matters.

The two units

Cup (cup): The US customary cup used in American recipes holds 8 US fluid ounces or 16 tablespoons, exactly 236.5882365 mL. US nutrition labels round it to 240 mL, and the metric cup used in Australia and many other countries is 250 mL.

Gram of Butter (g butter): Grams of butter, converted at 1 US cup = ½ lb = 226.8 g (about 0.959 g/mL), the ratio on US butter packs where 2 sticks make a cup; USDA lists 227 g per cup. A tablespoon of butter weighs about 14.2 g.
