1 Cup Oil in Grams: Vegetable, Olive and Coconut Oil Chart

Most liquid oils weigh close to the same per cup. Coconut oil is often solid at room temperature, so it is scooped and packed like butter. These values come from King Arthur Baking and USDA data.

Why Charts Disagree on Oil

King Arthur Baking rounds a cup of vegetable oil to 7 ounces, or 198 grams. USDA weighs a cup of olive oil at 216 grams, which matches oil’s real density more closely. The gap is about 18 grams per cup, or a little over 1 tablespoon.

Oil Is Lighter Than Water

A cup of water weighs about 237 grams, while a cup of olive oil weighs 216 grams. Oil weighs about 0.91 grams per ml, so it floats on water. That is why a cup of oil always weighs less than a cup of water.

This cups to grams oil chart covers every spoon and cup size found in cakes, muffins and dressings. The first column is the value used across this site. Use the olive oil or coconut oil column when a recipe names that oil.

1/4 Cup Oil in Grams

1/4 cup oil in grams is 50 grams for vegetable oil. A quarter cup of olive oil weighs 54 grams, and a quarter cup of coconut oil weighs 57 grams. That amount equals 4 tablespoons.

1/2 Cup and 1/3 Cup of Oil in Grams

Half a cup of vegetable oil weighs 99 grams. A third of a cup weighs 66 grams. Half a cup of olive oil weighs 108 grams.

European recipes often list oil in grams. Divide the grams by 198 to get cups of vegetable oil, or by 12.4 to get tablespoons. The last column gives the closest cups and spoons to pour.

100 Grams of Oil to Cups

100 grams of vegetable oil is 0.51 cup, which is about 1/2 cup. For olive oil, 100 grams is 0.46 cup, a little under 1/2 cup. 50 grams of vegetable oil is exactly 1/4 cup.

Oil in ML and Grams

A US cup holds 236.6 ml (NIST), so 1 cup of olive oil is 236.6 ml and 216 grams. To change ml of oil to grams, multiply by 0.91. For 100 ml of olive oil, 100 × 0.91 = 91 grams.

A cup of butter weighs about 227 grams, while a cup of vegetable oil weighs 198 grams. Butter is also not pure fat. US law requires butter to contain at least 80 percent milk fat (21 U.S.C. 321a), and the rest is mostly water.

Melting Coconut Oil

Coconut oil turns liquid when warm and solid when cool. Measure it in the state your recipe asks for. If you need melted coconut oil by weight, weigh it solid first, since the grams stay the same when it melts.

You only need one number for each oil. Use 198 grams per cup for vegetable oil and 216 grams per cup for olive oil. Multiply cups by that number to get grams, or divide grams by it to get cups.

Cups to Grams

For 3/4 cup of vegetable oil, 0.75 × 198 = 149 grams. For 1/3 cup of olive oil, 0.33 × 216 = 72 grams. For 2 tablespoons, 2 × 12.4 = 25 grams.

Grams to Cups

For 250 grams of vegetable oil, 250 ÷ 198 = 1.26 cups, or about 1 1/4 cups. For 150 grams, 150 ÷ 198 = 0.76 cup, or about 3/4 cup. For olive oil, divide by 216 instead.

Tips for Measuring Oil

Oil is easy to pour but tends to cling to cups. These habits help you get the full amount into the bowl. They matter most in cakes and quick breads.

• Use a liquid measuring cup. Read the line at eye level on a flat counter.
• Weigh it in the bowl. Set the bowl on a scale and pour oil straight in.
• Measure oil before honey. A cup with a film of oil lets honey or syrup slide out.
• Match the oil type. Olive and coconut oil weigh more per cup than vegetable oil.
• Check coconut oil’s state. Solid and melted coconut oil fill a cup differently.
