How many grams are in 1 cup of vegetable oil?

One US cup of vegetable oil weighs approximately 218 grams. This is based on the standard reference density for cooking oils of about 0.92 g/mL multiplied by 236.6 mL (one US cup). The exact value can vary slightly by oil brand and temperature.

Why is vegetable oil lighter than water by weight?

Vegetable oil has a density of roughly 0.92 g/mL, compared to water's 1.00 g/mL. A cup of vegetable oil therefore weighs about 218 grams versus 237 grams for a cup of water. Always use an oil-specific density for accurate recipe conversions.

How many tablespoons are in 1/4 cup of vegetable oil?

There are 4 tablespoons in 1/4 cup. One tablespoon of vegetable oil weighs approximately 13.6 grams, so 1/4 cup equals about 54.5 grams.

Can I substitute another oil at the same gram weight?

Most neutral vegetable oils (canola, sunflower, corn, soybean) have very similar densities (0.91-0.92 g/mL), so a 1:1 gram-for-gram substitution works well for most recipes.

How many grams is 1/2 cup of vegetable oil?

Half a cup (8 tablespoons) of vegetable oil is approximately 109 grams.

Does temperature affect vegetable oil weight?

Yes, but only slightly. Oil expands a little when heated and contracts when chilled, changing density by a small fraction of a percent. For everyday cooking conversions, the standard 218 g per cup figure is accurate enough.
