Olive Oil: Cups to Grams
Quick answer: One US cup of olive oil weighs about 216 grams (7.6 oz), and one tablespoon about 14 g.
US recipes measure olive oil in cups; the rest of the world weighs it. Convert any amount in either direction — and measure it the way the chart assumes: oil is lighter than water — a cup weighs 216 g, not 237 — and all liquid cooking oils weigh about the same.

How it works
Cups measure volume and grams measure weight, so the conversion runs through density: olive oil packs about 216 g into a US cup (237 ml). Volume is only as accurate as your technique — oil is lighter than water — a cup weighs 216 g, not 237 — and all liquid cooking oils weigh about the same. That variability is exactly why serious baking recipes list grams, and why a $15 kitchen scale upgrades every bake. If your recipe uses metric cups (250 ml), the weights run about 5% higher.
Frequently asked
How many grams are in a cup of olive oil?
About 216 grams (7.6 oz) per US cup, measured properly. A tablespoon is about 14 g.
How many cups is 250 g of olive oil?
About 1.16 cups. Divide any gram amount by 216 to get cups — or flip the converter above to grams and it does it for you.
Do other oils weigh the same per cup?
Within a gram or two, yes — vegetable, canola, sunflower and avocado oil all run ~215–220 g per cup, so this page's chart works for any liquid cooking oil.
