Quick Answer
One US cup of olive oil weighs about 216 grams. That works out to 13.5 g per tablespoon and 4.5 g per teaspoon. Extra virgin olive oil, ~0.91 g/mL. Weights vary slightly by brand, moisture, and how tightly you pack - for precise baking, a kitchen scale beats volume measures.

Frequently Asked Questions
How many grams in 1 cup of olive oil?
About 216 grams, scoop-and-level for dry ingredients. Extra virgin olive oil, ~0.91 g/mL.
How many grams in a tablespoon of olive oil?
One US tablespoon (15 mL) of olive oil is about 13.5 grams. A teaspoon is 4.5 g.
Why does olive oil weigh more (or less) than water?
Its density differs from water's 1 g/mL: 1 cup of olive oil weighs 216 g versus 237 g for water. Denser liquids (honey, syrup) weigh more per cup; oils weigh less.
How many cups is 100 g of olive oil?
100 g ÷ 216 g/cup ≈ 0.46 cups - about a little less than a full cup. The reverse table on this page covers 25-1000 g.
Should I weigh or measure by volume?
Weighing is more accurate - volume measures vary with how you scoop, pack, and level, and brands differ by 5-15%. For cookies and cakes where ratios matter, grams are the professional standard. The tables here convert either direction.
