How Many Grams Are in a Cup of Butter and Oil?

One US cup of butter weighs 226.8 g. That is two sticks, or 16 tablespoons, and each stick is 4 ounces by weight, or 113.4 g.^[1][2] Oils and other fats weigh less per cup than butter:

• Butter: about 226.8 g per cup (1 stick is 113.4 g)
• Margarine, stick: about 222 g per cup
• Vegetable shortening: about 191 g per cup (the charts give 184 to 205 g)
• Vegetable oil: about 223 g per cup (the charts give 198 to 224 g)
• Olive oil: about 216 g per cup

This site fixes butter at 226.8 g per cup because a stick is 4 ounces and a cup is two sticks,^[1] and the charts we read, which include King Arthur Baking, Baking Like a Chef and Pastry by Saloni, round that to between 225 and 227 g.^[3] To convert any amount, use the Grams to Cups converter, the Cups to Grams converter or the Butter Sticks Converter.

Butter by the stick, tablespoon and cup

A US stick is half a cup, 8 tablespoons and 4 ounces by weight.^[1] In most countries butter is sold in packets by weight, often 250 g or 500 g.^[4] A 250 g packet is a little over two sticks (2.2), or about 1 cup + 2 tbsp; the grams-to-cups table below has the other amounts. Ounces here are weight ounces of 28.35 g, not fluid ounces.^[2]

Grams per cup for butter, shortening and oil

The weights are for solid butter and stick margarine, shortening pressed into the cup and leveled, and oils measured as liquids.^[3] The range shows the lowest and highest figure among the charts we read, read on 8 October 2026. A tablespoon is a sixteenth of a cup and a teaspoon a forty-eighth, so those weights are the cup weight divided by 16 and by 48. The charts disagree by more than 10 percent for vegetable shortening and vegetable oil; treat those middle values as a close guide.

The margarine figures are for stick margarine, and the middle value of 222 g comes from only 2 charts, 217 and 227 g. Tub margarines and spreads are not covered and may weigh differently.

Fats in grams for common cup and spoon amounts

Cup weights are rounded to the nearest gram; spoon amounts and anything under 20 g show one decimal. A tablespoon of butter is about 14.2 g and a teaspoon about 4.7 g.

Grams to cups: how much is 100 g of butter?

The Cups column is exact for 226.8 g per cup. The next column rounds to the nearest tablespoon, because a cup holds 16 tablespoons. For vegetable oil at 223 g per cup, 100 g is 0.45 cup.

Why oil weights differ between charts

Oil is less settled than butter. The charts we read give 198, 223.3 and 224 g for a cup of vegetable oil, so the middle value of 223 g sits near the top of a spread from 198 to 224 g.^[3] A cup of vegetable oil weighs less than a cup of water (237 g): about 6 percent less by the middle value, and about 16 percent less by the lowest chart figure.

Figures that were read but left out of the middle values, with the reason for each, are listed in the Sources section of the Ingredient Weight Chart.

How to measure butter and oil

• Butter: for a recipe in sticks or tablespoons, use the tablespoon markings on the wrapper if it has them. For a recipe in grams, weigh it on a scale instead.
• Shortening: press it into the measuring cup so there are no gaps, then level the top.
• Oil: use a liquid measuring cup, set it on a flat surface and read it at eye level.^[5]
• On a scale, set the bowl on it, press tare, and add the fat until the display shows the weight in the recipe.

Flour and sugar are covered on the flour page and the sugar page. The Grams vs Cups guide explains why cups differ between countries.
