Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of vegetable oil weighs about 7.69 oz. Why these two are not the same. Decimals for thirds are rounded (1/3 cup is 0.333 cups), and each linked amount opens a page comparing every ingredient at that measure.

About measuring vegetable oil
Vegetable oil is lighter than water, which is why oil floats, so a cup weighs less than a cup of water. One US cup is about 218 grams. Most cooking oils, from sunflower to canola to light olive oil, are close enough in density to use the same figure. Oil measures cleanly by volume, but weighing is convenient in cakes and batters where you are already using a scale for the flour and sugar, keeping everything in one system.
Oil is lighter than water because it floats. Most cooking oils share the same density.
How many grams is a cup of vegetable oil?
One US cup (240 ml) of vegetable oil weighs about 218 grams. Because a cup measures volume rather than weight, that figure is specific to vegetable oil and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of vegetable oil is about 55 grams
- 1/3 cup of vegetable oil is about 73 grams
- 1/2 cup of vegetable oil is about 109 grams
- 2/3 cup of vegetable oil is about 145 grams
- 3/4 cup of vegetable oil is about 164 grams
- 1 1/2 cups of vegetable oil is about 327 grams
- 2 cups of vegetable oil is about 436 grams
- 3 cups of vegetable oil is about 654 grams
Working the other way round, 100 grams of vegetable oil is about 0.459 cups, and 500 grams is about 2.29 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of vegetable oil comes to about 227 grams, and the old British imperial cup of 284.1 ml holds about 258 grams. See cup sizes by country for every standard side by side.
Frequently asked questions
How many grams is 1 cup of vegetable oil?
One US cup of vegetable oil is about 218 grams. Oil is lighter than water, so a cup weighs less than a cup of water.
Do different oils weigh the same?
Very nearly. Sunflower, canola, olive and other cooking oils all sit close to 218 grams per cup, so you can use the same figure for most recipes.
How many grams is a tablespoon of oil?
About 13.6 grams. A cup of oil is around 218 grams and there are 16 tablespoons in a cup, giving roughly 13.6 grams each.
What else is vegetable oil called?
Vegetable oil is also called sunflower oil, canola oil or rapeseed oil. This site treats these names as the same product, so the figures on this page apply to all of them: one US cup weighs 218 grams.
How many grams is 1.33 cups of vegetable oil?
1.33 cups of vegetable oil weighs 290 grams. If the recipe means 1 1/3 cups, use 291 grams.
Is 1.33 cups the same as 1 1/3 cups?
Near enough for cooking. 1 1/3 cups is 1.333 cups, so with vegetable oil the two differ by 0.727 grams: 290 grams against 291 grams.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of vegetable oil. The 218 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
