How to measure vegetable oil

Oils weigh less than water per cup because they are less dense.

Because a cup measures volume rather than weight, the most reliable way to measure vegetable oil is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Vegetable oil conversions: FAQ

Why doesn't a cup of vegetable oil weigh the same as a cup of water?

A cup measures volume, not weight. Vegetable oil is less dense than water (218 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
