1 Cup Coconut Oil in Grams
1 cup of coconut oil weighs 218 g (poured, USDA). Oil from coconut flesh, solid below about 24 C with a mild coconut flavour. All the figures on this page are approximate conversions based on the USDA value, so when a recipe really matters, verify with a kitchen scale.
Why weighing coconut oil beats measuring it in cups
A cup of fat is one of the least reliable cup measures in the kitchen. Solid fats trap air when scooped, liquid fats cling to the sides of the cup, and both behave differently at different temperatures. Butter straight from the fridge packs differently from butter that has softened on the counter. Grams cut through all of that: 227 g of butter is 227 g of butter whatever the temperature, and the recipe works the same way every time.
Oil from coconut flesh, solid below about 24 C with a mild coconut flavour. It is used for baking, frying, curries and dairy-free recipes. 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.

| 4 cups | 872 g | 54.5 g |
The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of coconut oil weighs about 13.6 g. Remember that 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.
How the weight was measured
Poured means the ingredient is a liquid or a free-flowing syrup, so it is measured in a liquid measuring jug with a spout, read at eye level. Liquids settle flat, so there is no packing or levelling to worry about, but a sticky liquid will cling to the jug, which is one more reason to weigh it instead.
The source for the 218 g 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. There is a dispute worth knowing about. Measured melted at 218 g per cup; solid coconut oil packs at about 227 g per cup, like butter. The practical advice is simple: use the value in the table above, measure the way the table describes, and your results will match the recipes this site is built around. If a recipe you are following was written with a different value, follow that recipe's value instead of ours, because consistency within one recipe matters more than which authoritative number you pick.
Worked examples
A double batch of brownies
Doubling brownies that use 1 cup of coconut oil means 2 cups, or 436 g. Brownies are rich and the fat ratio decides whether they are fudgy or cakey, so weighing 436 g keeps the doubled batch identical to the original.
A pie crust with 1 cup of fat
A pie crust asking for 1 cup of coconut oil needs 218 g. Pastry is the least forgiving place for a measuring error: too much fat and the crust slumps, too little and it turns tough. Weighing 218 g is the difference between a flaky crust and a disappointing one.
A cake that needs half a cup
A cake recipe asking for 1/2 cup of coconut oil needs 109 g. Half a cup of a solid fat is hard to measure accurately in a cup, because it never fills the corners evenly. Weighing 109 g straight into the bowl is faster and more accurate.
When this conversion matters most
This conversion matters most in pastry and cakes, where fat is doing structural work. Shortcrust pastry, puff pastry and laminated doughs all depend on a precise ratio of fat to flour, and a cup of fat measured badly will throw that ratio off. It also matters when you are substituting one fat for another: butter, oil and shortening do not weigh the same per cup, so swapping them by volume is a mistake. Convert by weight, and the substitution behaves as expected.
Common mistakes with coconut oil
- Measuring melted fat in a dry cup. Melted fat should be measured in a liquid jug or weighed, not scooped into a dry cup, because it clings and pours unevenly.
- Guessing a tablespoon of butter. Butter packaging is marked in tablespoons for a reason. One stick is 113 g, which is half a cup, and cutting by the marks is more accurate than eyeballing.
- Using cold butter volume for a recipe that needs softened. Cold butter packs more densely than softened butter. Weigh it instead of relying on the cup, and the temperature stops mattering.
- Leaving fat in the measuring cup. Oil and melted butter cling to the cup, so what you measured is not what reached the bowl. Weighing in the mixing bowl avoids the loss entirely.
Storage and handling
Cool cupboard; solid or liquid both keep for up to 1 year. Keeping coconut 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.
Frequently asked questions
How many grams is 1 cup of coconut oil?
1 cup of coconut oil weighs 218 g, measured poured according to USDA. That is the figure to use when converting a recipe from cups to grams, and it is the value the conversion table on this page is built on.
How do I measure coconut oil without a scale?
Poured means the ingredient is a liquid or a free-flowing syrup, so it is measured in a liquid measuring jug with a spout, read at eye level. Liquids settle flat, so there is no packing or levelling to worry about, but a sticky liquid will cling to the jug, which is one more reason to weigh it instead. That gives the closest result to 218 g per cup, but it is still an estimate: the honest answer is that a scale is the only way to know the exact weight, and a basic digital kitchen scale costs less than a bag of good flour.
Does coconut oil always weigh the same per cup?
No. Brand, grind, moisture and how settled the container is all shift the weight by a few grams, and for flour the swing can be 20 g or more. The 218 g figure is the standard USDA value for coconut oil measured poured, and it is the right default, but when a recipe is precise, weigh the ingredient and trust the scale over the cup.
Why do different websites give different weights for coconut oil?
Because they are measuring different things. Measured melted at 218 g per cup; solid coconut oil packs at about 227 g per cup, like butter. A source that scoops will always report a heavier cup than a source that spoons and levels, and both can be correct about their own method. The fix is to pick one source and one method and stick with it for the whole recipe.
How should I store coconut oil?
Cool cupboard; solid or liquid both keep for up to 1 year. 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.
What is coconut oil used for?
Baking, frying, curries and dairy-free recipes. Oil from coconut flesh, solid below about 24 C with a mild coconut flavour.
