Grams to cups: vegetable oil
Working backwards from a weight? Here is how common gram amounts of vegetable oil convert to cups (at 218 g per cup).
| Grams | Cups | Tablespoons | Ounces |
|---|---|---|---|
| 10 g | 0.05 cups | 0.7 tbsp | 0.4 oz |
| 25 g | 0.11 cups | 1.8 tbsp | 0.9 oz |
| 50 g | 0.23 cups | 3.7 tbsp | 1.8 oz |
| 75 g | 0.34 cups | 5.5 tbsp | 2.6 oz |
| 100 g | 0.46 cups | 7.3 tbsp | 3.5 oz |
| 125 g | 0.57 cups | 9.2 tbsp | 4.4 oz |
| 150 g | 0.69 cups | 11 tbsp | 5.3 oz |
| 200 g | 0.92 cups | 14.7 tbsp | 7.1 oz |
| 250 g | 1.15 cups | 18.3 tbsp | 8.8 oz |

| 500 g | 2.29 cups | 36.7 tbsp | 17.6 oz |
Measuring vegetable oil accurately
Read oil in a clear liquid cup at eye level, and since it's slippery there's no need to grease anything. It measures cleanly, but pouring straight onto a kitchen scale at 218g per cup saves a cup to wash and avoids the thin film left behind.
Recipe just says "oil"? Every cooking oil weighs about the same
If a recipe calls for plain oil — no type given — this page applies as written. Per USDA data, every common liquid cooking oil weighs between 216 and 218 g per US cup (a density of 0.91–0.92 g/mL), a spread smaller than ordinary measuring error. So 1 cup of oil is about 218 g, 1/2 cup about 109 g and 1/4 cup about 54.5 g, whether you pour vegetable, canola, sunflower or corn oil.
| Oil | Grams per US cup | g/mL |
|---|---|---|
| Vegetable / soybean oil | 218 g | 0.92 |
| Canola oil | 218 g | 0.92 |
| Sunflower oil | 218 g | 0.92 |
| Corn oil | 218 g | 0.92 |
| Coconut oil (melted) | 218 g | 0.92 |
| Olive oil | 216 g | 0.91 |
| Peanut oil | 216 g | 0.91 |
Note that oil is lighter than water: a US cup of water weighs about 237 g against oil's ~218 g, which is why oil floats and why the handy water rule "1 mL = 1 g" overshoots for oil — multiply millilitres by 0.92 instead (100 mL ≈ 92 g). You may also meet 198 g per cup on some baking charts: that's King Arthur's rounded 7-oz figure under the old 8-oz-cup convention, not a real density — measured, no cooking oil is that light.
Using oil in place of butter? That swap isn't 1:1 — the standard rule is 3 parts oil per 4 parts butter, so 1 stick of butter becomes 6 tablespoons (about 81 g) of oil. The butter to oil conversion has the full chart in cups, grams and mL.
Frequently asked questions
How many grams is 1 cup of vegetable oil?
1 US cup of vegetable oil weighs about 218 grams.
How many grams is 3/4 cup of vegetable oil?
Three quarters of a US cup of vegetable oil is about 163.5 grams (12 tablespoons).

2/3 of a US cup of vegetable oil is about 145.3 grams.
How many grams is 1/2 cup of vegetable oil?
Half a US cup of vegetable oil is about 109 grams — half of the 218 g in a full cup.
How many grams is 1/3 cup of vegetable oil?
A third of a US cup of vegetable oil is about 72.7 grams.
How many grams is 1/4 cup of vegetable oil?
A quarter US cup of vegetable oil is about 54.5 grams (4 tablespoons).
How many grams is 1 tablespoon of vegetable oil?
1 tablespoon of vegetable oil is about 13.6 grams (a cup is 16 tablespoons).
How many grams is 1 1/4 cups of vegetable oil?
1 1/4 US cups of vegetable oil weigh about 272.5 grams.
How many grams is 1 1/2 cups of vegetable oil?
1 1/2 US cups of vegetable oil weigh about 327 grams — one full cup (218 g) plus half a cup (109 g).
How many grams is 2 cups of vegetable oil?
2 US cups of vegetable oil weigh about 436 grams.
How many cups is 100 grams of vegetable oil?
100 grams of vegetable oil is about 0.46 cups.
How many cups is 250 grams of vegetable oil?
250 grams of vegetable oil is about 1.15 cups (at 218 g per cup).
How many cups is 500 grams of vegetable oil?
500 grams of vegetable oil is about 2.29 cups.
How many grams is 1 cup of oil?
About 218 grams for any common liquid cooking oil. Per USDA data, vegetable, canola, soybean, corn, sunflower and melted coconut oil all weigh 218 g per US cup, with olive and peanut oil just behind at 216 g — so if a recipe only says "oil", the chart on this page applies within a gram or two.
Do all cooking oils weigh the same per cup?
Very nearly. Every common liquid cooking oil falls between 216 and 218 grams per US cup (a density of 0.91–0.92 g/mL): vegetable, canola, soybean, corn, sunflower and melted coconut oil at 218 g, olive and peanut oil at 216 g. The differences are smaller than normal measuring error, so oils can be swapped by volume without re-weighing.
Does a cup of oil weigh the same as a cup of water?
No — oil is lighter. A US cup of water weighs about 237 grams, while a cup of cooking oil weighs about 218 grams (density ~0.92 g/mL). That density gap is exactly why oil floats on water, and why you can't use the water rule "1 mL = 1 g" for oil.
How many grams is 100 mL of oil?
About 92 grams (at ~0.92 g/mL). To convert any millilitre amount of oil to grams, multiply the mL by 0.92; a full US cup is 236.59 mL, or about 218 g.
Why do some baking charts say 1 cup of oil is 198 grams?
That figure is a rounding artifact, not a different measurement. King Arthur's ingredient chart lists vegetable oil as a rounded 7 oz (198 g) and uses the old 8-oz-cup convention (it lists water at 227 g, though a US cup of water really weighs 236.6 g). Measured density puts every common cooking oil at 0.91–0.92 g/mL, which works out to 216–218 g per US cup — the USDA value this page uses. 198 g/cup would imply a density of 0.84 g/mL, which no cooking oil has.
