A 500 ml bottle of olive oil holds about 2.1 cups. Because oil is measured by volume, this one is exact arithmetic: a US cup is 236.6 ml, so 500 divided by 236.6 gives 2.11 cups. The bottle is the standard supermarket size, and two cups plus a little is enough for several weeks of everyday cooking — a vinaigrette here, a roast there — before you need another.
How many cups in a 500 ml bottle?
A 500 ml bottle of olive oil holds about 2.1 cups (500 ml ÷ 236.6 ml per cup).
| Amount | Cups | Millilitres | Tablespoons | Grams (approx.) |
|---|---|---|---|---|
| Full 500 ml bottle | 2.1 | 500 | 34 | 456.47 |
| Half 500 ml bottle | 1.05 | 250 | 17 | 228.23 |
| Quarter 500 ml bottle | 0.53 | 125 | 8 | 114.12 |
| 1 tablespoon | 0.06 | 14.8 | 1 | 13.51 |
The table gives the full package, half a package and a quarter of a package, plus a single tablespoon, so you can scale the answer to whatever your recipe asks for. If your packet is a different size from the one on this page, the same per-cup figure still applies — divide your packet's weight by the grams per cup, or its volume by 236.6 ml per cup, and you have your answer.
Worked examples
Vinaigrette that needs half a cup
A jar of vinaigrette for a week's salads takes 1/2 cup of olive oil — about 118 ml — whisked with 3 tablespoons of vinegar, 1 teaspoon of mustard and a pinch of salt. That is roughly a quarter of the bottle, so one 500 ml bottle makes about four jars of dressing. Shake the jar before each use: oil and vinegar separate within minutes, and an unshaken dressing pours out as pure oil for the first salad and pure vinegar for the second.
Focaccia that needs a quarter of a cup
A focaccia dough takes about 1/4 cup of olive oil in the dough — around 59 ml — plus another 2 tablespoons drizzled over the top before baking. The oil in the dough keeps the crumb tender, and the oil on top is what makes the dimpled surface crisp and golden. A 500 ml bottle covers eight focaccias at that rate, which is why the bottle lasts so long in a baking household. Use your best oil for the drizzle and an everyday one in the dough.
Roasting vegetables that need three tablespoons
A tray of roast vegetables for four people needs about 3 tablespoons of olive oil — 44 ml — tossed with the vegetables before they go into the oven. Three tablespoons is a small fraction of the bottle, about a tenth, so one bottle covers roughly eleven trays. The mistake is pouring straight from the bottle over the tray: it is easy to use twice as much as intended. Measure into a spoon first, or pour into a small jug, and the vegetables roast instead of frying in a pool.
How the figure was measured
The weight figures on this page come from USDA: olive oil weighs about 216 g per cup, measured poured, and that figure carries high confidence in CookScale's 120-ingredient table. But the cup figures themselves do not depend on weight at all — a cup is 236.6 ml whether it holds oil, milk, cream or soy sauce — so the headline answer is exact arithmetic, not an estimate. The gram figures are the approximate ones, because they depend on density, and they should be verified with a kitchen scale when a recipe gives grams and the amount matters. Package sizes vary by brand and region, so check the volume printed on your own bottle or carton before planning around this page.
There is a dispute note on this figure: the King Arthur chart lists olive oil at 200 g per cup, while the USDA density of 0.91 g per ml gives 216 g per cup. CookScale uses the USDA density value.
How to measure it
Oil is measured by volume, which makes this page simpler than the dry-ingredient ones: a cup is 236.6 ml no matter what is in it, so the bottle's millilitres divide cleanly into cups. Use a liquid measuring jug with a spout, read it at eye level on a flat counter, and let the oil settle — a jug tilted in your hand reads a tablespoon high. For small amounts a tablespoon measure is more accurate than eyeballing a jug line. If a recipe gives grams instead, weigh the oil: it is lighter than water, so 1 cup of olive oil is about 216 g and 1 cup of vegetable oil about 218 g, not 237 g. Mixing up oil and water weights is the most common conversion error in baking.
Practical guidance
Oil goes rancid long before it looks or smells obviously wrong, and a 500 ml bottle opened for occasional cooking can sit for months. Store it in a cool, dark cupboard away from the stove — heat and light are what turn it. Taste a drop before using an old bottle in a vinaigrette: if it is bitter or sharp in a stale way, it is past its best and will carry that flavour into everything. Never pour used oil back into the fresh bottle, and keep the cap on: oil absorbs strong smells from the pantry. For frying, measure what you need into the pan rather than pouring from the bottle over a hot hob, where a slip becomes a fire risk.
Two cups plus a little is the practical way to think of a 500 ml bottle: it covers two cups for a recipe with a tablespoon or two to spare. If a recipe calls for exactly 2 cups — a large batch of mayonnaise, say — you can pour the whole bottle in and be within a tablespoon. For baking, weigh the oil rather than measuring by the cup: 216 g per cup is the USDA figure, and a scale is more accurate than a jug when the recipe gives grams. And check the label for the bottle size before you start — 750 ml bottles are common too, and those hold about 3.2 cups.
Frequently asked questions
How many cups are in a 500 ml bottle of olive oil?
There are about 2.1 cups in a 500 ml bottle of olive oil. A US cup is 236.6 ml, so 500 ml divided by 236.6 ml gives 2.11 cups. In tablespoons that is about 34 tablespoons. The figure is exact for volume — oil and water both fill a cup the same way — even though a cup of olive oil weighs less than a cup of water.
How many grams are in a 500 ml bottle of olive oil?
A 500 ml bottle of olive oil weighs about 456 g. Olive oil is lighter than water at about 0.91 g per ml, and the USDA figure is 216 g per cup. Do not use 500 g as the weight: that would overstate the oil by nearly 10 percent, which matters in baking where the fat is weighed.
Is a 500 ml bottle the same as a litre bottle?
No. A 500 ml bottle is half a litre, and a 1 litre bottle holds about 4.2 cups — double the 2.1 cups in a 500 ml bottle. If a recipe calls for a cup of oil and you are buying for a big cooking session, the litre bottle is usually better value per millilitre, but it goes rancid faster once opened, so a smaller bottle is better for occasional use.
Can I use vegetable oil instead of olive oil cup-for-cup?
Yes, vegetable oil substitutes cup-for-cup for olive oil in volume — a cup is a cup. The difference is flavour and smoke point: olive oil adds a fruity, peppery note and smokes at a lower temperature, while vegetable oil is neutral and handles higher heat. For a vinaigrette the swap changes the dressing completely; for frying, it is barely noticeable.
How long does an opened bottle of olive oil last?
An opened bottle of olive oil is at its best for one to three months, though it stays safe to use for longer. Store it in a cool, dark cupboard away from the stove. Taste a drop before using an old bottle in a salad: rancid oil tastes bitter and stale, and it will carry that flavour into everything it touches.
