Millilitres of vegetable oil to grams runs on one number, 0.92143212 grams per millilitre. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
Water is the yardstick: 1 mL of it weighs 1 g. Vegetable oil comes in at 0.92143 g per mL, or 92.14% of water, which is why a cup of it is 218 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
Vegetable oil has a density of 0.92143 g per mL, so 100 mL of it weighs 92.14 g and 250 mL weighs 230.4 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 92.14% as heavy as the same volume of water.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.459% of a cup of vegetable oil, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.294 cups, and a 1 kg pack 4.587.
The condition this weight assumes: Every culinary oil is about 92% the density of water, which is precisely why oil floats on it.
The formula
millilitres- The amount of vegetable oil you are converting, in millilitres
0.921432118625- Grams per millilitre for vegetable oil, from its density of 0.92143 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in millilitres.
- It is multiplied by 0.921432118625, the grams-per-millilitre figure for vegetable oil.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
15 mL of vegetable oil in grams
A recipe calling for 15 mL of vegetable oil needs 13.8215 grams on the scale. The arithmetic is 15 × 0.92143212 = 13.821482, and halving the recipe halves the weight to 6.91074 grams.
100 mL of vegetable oil in grams
100 mL of vegetable oil weighs out at 92.1432 grams. Divide 92.1432 by 0.92143212 and you get back to 100 mL, which is the quickest check that the factor is the right way up.
250 mL of vegetable oil in grams
A recipe calling for 250 mL of vegetable oil needs 230.358 grams on the scale. The arithmetic is 250 × 0.92143212 = 230.35803, and halving the recipe halves the weight to 115.179 grams.

Frequently asked questions
How many grams are in 1 mL of vegetable oil?
One millilitre of vegetable oil is 0.92143212 grams. Half that quantity is 0.460716 grams and double it is 1.84286 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of vegetable oil not 236 g like water?
Because weight per cup depends on what is in the cup. Vegetable oil has a density of 0.92143 g per mL where water has 1.00, so a cup of it weighs 218 g rather than 236.6 g. That is a difference of 18.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Barely. Vegetable oil does not compress, so a cup of it is 218 g however it is poured — within about 1%, which is inside the accuracy of a domestic scale. This is the group where measuring by volume is defensible.
Is a fluid ounce of vegetable oil the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of vegetable oil weighs 0.9612 oz, so the two readings differ by 3.88%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of vegetable oil would weigh 230.36 g instead of 218 g — 12.4 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One millilitre of vegetable oil is 0.9214 g, and a scale reading to the nearest gram is working at 109% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How many millilitres of vegetable oil is 500 g?
500 g of vegetable oil is 542.63 millilitres — 1.08527 millilitres to one gram, so 500 × 1.08527 = 542.63. Going that way is a division by 0.921432, or a multiplication by 1.08527 if you prefer.
