1/4 Cup Olive Oil in Grams
1/4 cup of olive oil weighs 54 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.
Why a quarter cup is worth weighing
A quarter cup is a small measure, and small measures are where cup errors hurt most. A 5 g mistake in a full cup of olive oil is a rounding error; the same 5 g on a quarter cup is a 17 percent swing on 54 g, and in a small batch that swing can change the result. Recipes that call for a quarter cup are usually small, precise or both — a mug cake, a glaze, a roux, a single-serve bake — and there is no large batch to absorb the error. Weighing 54 g takes five seconds and removes the problem entirely.
Poured is the method behind the number, and it matters. Olive Oil 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. Grams cut through all of that: 54 g of olive oil is 54 g whatever the brand, the humidity or the size of your measuring cup.

| Cups | Grams | Tablespoons |
|---|---|---|
| 1/4 cup | 54 g | 4 |
| 1/3 cup | 72 g | 5.3 |
| 1/2 cup | 108 g | 8 |
| 2/3 cup | 144 g | 10.7 |
| 3/4 cup | 162 g | 12 |
| 1 cup | 216 g | 16 |
| 1 1/2 cups | 324 g | 24 |
| 2 cups | 432 g | 32 |
The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of olive oil weighs about 13.5 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 1/4-cup row outwards: every other row is a multiple of 54 g, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Poured means the ingredient is measured the way USDA measures it: poured. For olive oil, that gives 216 g per cup, and a quarter of that is 54 g. The source for the figure is USDA, and the confidence in the value is high. USDA publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
A note on disputed figures. USDA gives 216 g per cup (0.91 g/ml); the King Arthur chart lists 200 g. We use the USDA density value. That is why this page uses the USDA value of 216 g per cup as its single, stated source, rather than averaging across charts. An average of two different measuring methods is a number that matches nobody's cup, so we pick one method, name it, and stick to it.
Worked examples
A single-serve mug cake
A mug cake uses about 1/4 cup of melted olive oil at most — usually far less — but a small cake for two can take the full 1/4 cup, which is 54 g. Fat is what keeps a mug cake moist instead of rubbery, and because the whole cake is one serving, an extra tablespoon of fat is a big share of the total. Weigh 54 g, melt it, and stir it in; the cake stays tender without turning greasy.
Frying two eggs
Frying two eggs takes about 1/4 cup of olive oil in the pan if you like them well basted — 54 g — though most cooks use less. The fat carries heat to the egg and stops it sticking, and the amount decides whether the white crisps at the edges or swims. Weighing 54 g once teaches you what that amount actually looks like in your pan, and after that you can pour by eye with confidence.
A stir-fry for two
A stir-fry for two needs about 1/4 cup of olive oil — 54 g — in a wok heated until it smokes faintly. The oil must be hot enough that the vegetables sizzle on contact and stay crisp, and too little oil means they steam instead. Weigh 54 g, swirl it around the wok, and add the ingredients in batches so the pan stays hot.
Solid, melted and poured are three different weights
For olive oil, the method is poured, and temperature changes the result. Solid fat traps air when scooped, melted fat pours cleanly, and the same fat weighed cold versus warm can differ by a few grams per cup. At quarter-cup scale that is a small difference in grams but a real one in a recipe that depends on fat for texture. Weigh 54 g in the state the recipe asks for, and do not swap a solid measure for a melted one without converting by weight.
Scaling a quarter cup up and down
Once you know that 1/4 cup of olive oil is 54 g, the rest is arithmetic. Half a cup is 108 g, three quarters is 162 g, and a full cup is 216 g. Doubling a recipe that calls for 1/4 cup means weighing 108 g; halving it means 27 g, which is 2 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 54 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with olive oil
- Measuring melted fat in a dry cup. Melted fat clings and pours unevenly in a dry cup. Weigh it, or use a liquid jug.
- Cutting butter by eye. Butter packaging is marked in tablespoons for a reason. One stick is 113 g, half a cup, and cutting by the marks beats guessing.
- Using a cold-fat volume for a softened recipe. Cold fat packs more densely than softened fat. Weigh 54 g and the temperature stops mattering.
- Leaving fat in the measuring cup. Oil and melted butter cling to the cup. Weighing into the mixing bowl avoids losing a gram or two on 54 g.
Storage and handling
Cool, dark place away from the stove; use within 6 months of opening. Keeping olive oil stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. Label the container with the conversion — 1/4 cup is 54 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of olive oil?
1/4 cup of olive oil weighs 54 g, measured poured according to USDA. That is one quarter of the full-cup weight of 216 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
Can I use the same conversion for a different brand of olive oil?
Yes, as a starting point. The 54 g figure is a standard average for olive oil, and most brands sit within a few grams of it. If you bake with one brand all the time, weigh a quarter cup of it once and note the number on the bag, and you will have a conversion tuned to your own kitchen.
How many tablespoons is 1/4 cup of olive oil?
There are 4 tablespoons in a quarter cup, whatever the ingredient. One tablespoon of olive oil weighs about 13.5 g, so 4 tablespoons come to about 54 g. For small amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
What is olive oil used for?
Dressings, roasting, frying and bread dipping. Oil pressed from olives; extra virgin is best uncooked, refined suits frying. A quarter cup — 54 g — is a common amount in small batches, glazes, sauces and test bakes, which is why this conversion comes up so often.
How should I store olive oil?
Cool, dark place away from the stove; use within 6 months of opening. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
Why do different charts give different weights for olive oil?
USDA gives 216 g per cup (0.91 g/ml); the King Arthur chart lists 200 g. We use the USDA density value. We use the USDA figure of 216 g per cup, measured poured, so a quarter cup is 54 g. If a recipe you trust uses a different figure, follow that recipe's chart for that recipe — but do not mix charts inside one recipe.
