How many grams are in 1 cup of Vegetable oil?
One US cup (240 ml) of vegetable (canola) oil weighs about 218 grams. A US customary cup (236.6 ml) holds about 215 g, a metric cup (250 ml) about 227 g, and an imperial cup (284.1 ml) about 258 g.
Cups of Vegetable oil to grams
One US cup (240 ml) of vegetable (canola) oil weighs about 218 grams (7.7 oz), measured liquid measure.
Vegetable oil is lighter than water — about 0.91 g per ml — so a US cup weighs 218 g, not 240 g. It is a stable liquid: brand and temperature barely move the figure.

How to measure Vegetable oil by volume
- Use a liquid measuring cup at eye level, or weigh it directly into the bowl.
- Canola, sunflower, corn and generic blends all measure within a few grams of each other.
Why the weight varies
Cooking oils are consistent liquids; brand and temperature change the weight of a cup by only a few grams.
Oil quantities set a bake’s richness and crumb moisture. The common mistake is assuming “1 cup = 240 g” for every liquid — for oil that overshoots by 10%, which is noticeable in a carrot cake.
Which value we publish, and why
We publish 218 g per US cup, the USDA figure for canola oil (density ≈ 0.91 g/ml); King Arthur rounds a cup of vegetable oil to 198 g (7 oz).
