3/4 Cup Olive Oil in Grams
3/4 cup of olive oil weighs 162 g (poured, USDA). Oil pressed from olives; extra virgin is best uncooked, refined suits frying. All the figures on this page are approximate conversions based on the USDA value of 216 g per cup, so when a recipe really matters, verify with a kitchen scale.
It is used for dressings, roasting, frying and bread dipping. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Knowing the weight of 3/4 cup, rather than guessing from a measuring cup, keeps the result consistent no matter which recipe you are following, and it lets you scale a recipe up or down without the errors multiplying.

One tablespoon of olive oil weighs about 13.5 g, and one teaspoon about 4.5 g. Three quarters of a cup is 12 tablespoons, and it occupies about 177 ml by volume, the same as 3/4 cup of anything, because volume does not change from one ingredient to the next. Only the weight changes, and that is why the table above is organised by weight rather than volume. The table is rounded to the nearest tenth of a gram where the fraction demands it, so the numbers are approximate by design; the 3/4 cup figure of 162 g is the one to use when a recipe calls for 3/4 cup.
How the weight was measured
Poured is the method used for this ingredient, and it matters because the same cup can hold a different weight depending on how it was filled. Spooned and levelled means spooning the ingredient into the cup and levelling the top with a straight knife, without packing it down. Packed means pressing the ingredient firmly into the cup until it holds its shape. Poured means pouring a liquid into a measuring jug up to the line. Scooped means pushing the cup through a solid fat and levelling the top.
The source for the 216 g per cup figure is USDA, and this page follows that value exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
USDA gives 216 g per cup (0.91 g/ml); the King Arthur chart lists 200 g. We use the USDA density value.
All the figures on this page are approximate conversions. When a recipe really matters, verify with a kitchen scale: weigh the ingredient directly into the bowl on a tared scale and trust that number over any cup.
Worked examples
A vinaigrette for a dinner party salad
A vinaigrette that calls for 3/4 cup of olive oil needs 162 g. A classic vinaigrette is three parts oil to one part vinegar, so 3/4 cup of oil pairs with 1/4 cup of vinegar, and the ratio is what makes it coat the leaves instead of pooling at the bottom of the bowl. Weighing the oil first, then adding the vinegar and mustard, keeps the emulsion balanced for a big salad that has to feed twelve.
Roasting vegetables for a Sunday lunch
Roasting a tray of Mediterranean vegetables with 3/4 cup of olive oil takes 162 g. The oil carries heat into the vegetables and helps them caramelise, and too little leaves them pale and dry while too much leaves them greasy. Weighing the oil lets you coat two trays evenly instead of drowning the first and starving the second.
A focaccia that needs a generous pour
A focaccia recipe calling for 3/4 cup of olive oil needs 162 g, split between the dough and the dimpled top. Olive oil is the flavour of focaccia, so this is a recipe where the quality of the oil matters as much as the amount: a peppery extra virgin oil gives the bread its character, while a neutral oil leaves it flat. Weighing keeps the dough hydration right and leaves enough oil for the top.
Why weighing 3/4 cup of olive oil beats measuring it in cups
Fat is the ingredient that decides whether a bake is tender or tough, flaky or dense, and 3/4 cup is an amount that appears in cakes, pastry, and roasting all the time. Weighing it matters because a cup is a poor way to measure a fat: solid fats trap air pockets when scooped, and liquid fats are hard to read in a measuring jug. A cup measure can be 10 g or more off, which is enough to change a cake from moist to greasy. Weighing removes that whole source of error, and it is faster than packing a cup and scraping it out.
When this conversion matters most
This conversion matters most in dressings and in breads, where olive oil is a flavouring as well as a fat. A vinaigrette with too much oil tastes flat and greasy; one with too little tastes sharp and thin. In focaccia and other oil-enriched breads, the oil changes the crumb and the crust, so the amount has to be right. For everyday frying, the exact weight hardly matters. One practical point: extra virgin olive oil and refined olive oil weigh the same per cup, so 162 g works for either, and the choice is about flavour and smoke point, not weight.
Storage
Cool, dark place away from the stove; use within 6 months of opening. Oil pressed from olives; extra virgin is best uncooked, refined suits frying. It is used for dressings, roasting, frying and bread dipping. Knowing how the ingredient is stored matters for the conversion too: an ingredient that has absorbed moisture or dried out will weigh differently per cup, so store it properly and weigh it fresh for the best results.
Common mistakes
The most common mistake is using the King Arthur chart figure of 200 g per cup, which gives 150 g for 3/4 cup, about 12 g light. The USDA density value of 216 g per cup is the reliable one, giving 162 g. A second mistake is storing olive oil next to the stove, where heat and light turn it rancid in weeks; keep it in a cool, dark cupboard instead. A third mistake is using expensive extra virgin oil for high-heat frying, where its flavour burns off and a cheaper refined oil would do the same job.
If you do not have a kitchen scale, the most reliable fallback is the tablespoon: 3/4 cup is 12 level tablespoons, and each one is levelled on its own, so the errors do not stack the way they do in a cup. Spoon dry ingredients in and level them off, and pour liquids in on a flat surface so the spoon is full but not heaped. It takes a minute longer than weighing, but it beats guessing from a cup, and for a dressing or a marinade it is accurate enough. For cakes and pastry, buy a scale when you can: it is the single cheapest upgrade to your baking.
Frequently asked questions
How many grams is 3/4 cup of olive oil?
3/4 cup of olive oil weighs 162 g, poured, using the USDA value of 216 g per cup. The figure is approximate, so verify with a kitchen scale when the recipe matters, especially for dressings and breads.
Why do some sources say 200 g per cup for olive oil?
The King Arthur Baking chart lists 200 g per cup for olive oil, but the USDA density of 0.91 g/ml gives 216 g per cup, which matches the measured density of olive oil. We use the USDA value, so 3/4 cup is 162 g rather than 150 g.
How many tablespoons is 3/4 cup of olive oil?
3/4 cup is 12 tablespoons, and one tablespoon of olive oil weighs about 13.5 g. That gives roughly 162 g for the full 12 tablespoons. Weighing is more accurate than counting spoonfuls, especially for a dressing where the ratio matters.
Does extra virgin olive oil weigh the same as regular olive oil?
Yes. Extra virgin and refined olive oil have the same density, so 3/4 cup of either weighs 162 g. The difference is flavour, colour, and smoke point, not weight, so use the same figure for both.
Can I swap olive oil for vegetable oil gram for gram?
Nearly: 3/4 cup of vegetable oil weighs 163.5 g against 162 g for olive oil, a difference of only 1.5 g. The swap works by weight in any recipe, but olive oil adds a fruity, peppery flavour that changes the result, so do not use it in a delicate cake where a neutral oil was intended.
