1/2 Cup Coconut Oil in Grams
1/2 cup of coconut oil weighs 109 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.
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. Knowing the weight of half a cup, rather than guessing from a measuring cup, keeps the result consistent no matter which recipe you are following.
Why weighing half a cup of coconut oil beats measuring it in cups
Fat is the ingredient that decides whether a bake is tender or tough, flaky or dense, and 1/2 cup of coconut oil weighs 109 g. That number matters because fat coats flour and shortens gluten strands, so a little too much makes a cake greasy and a little too little makes it dry. Cups are a poor way to measure a solid fat: scooping leaves air pockets, and a cup of soft fat packs differently from a cup of cold fat. Weighing 109 g on a scale removes all of that, and it is faster than packing a cup with a spoon.
Coconut Oil cups to grams conversion table
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 54.5 g |
| 1/3 cup | 72.5 g |
| 1/2 cup | 109 g |
| 2/3 cup | 145.5 g |
| 3/4 cup | 163.5 g |
| 1 cup | 218 g |
| 1 1/2 cups | 327 g |
| 2 cups | 436 g |
| 3 cups | 654 g |
One tablespoon of coconut oil weighs about 13.5 g, and one teaspoon about 4.5 g. 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. The table is rounded to the nearest half gram, so the numbers are approximate by design; the half-cup figure of 109 g is the one to use when a recipe calls for half a cup.
How the weight was measured
Poured means pouring the ingredient into a liquid measuring jug on a flat surface and reading the level at eye level. Liquids level themselves, so there is no spooning or levelling involved, and the weight follows directly from the volume and the density.
The source for the 218 g per cup 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.
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 batch of cookies
A cookie recipe calling for 1/2 cup of coconut oil needs 109 g. Weighing the fat means the dough has exactly the right tenderness, because the fat coats the flour evenly and the cookies spread the same way every time. If the recipe is doubled for a bake sale, use 218 g for 1 cup.
Halving a cake recipe
Halving a cake that asks for 1 cup of coconut oil leaves you with 1/2 cup, or 109 g. A half-cup measure of a solid fat is notoriously inaccurate because of air pockets, so weighing 109 g is the reliable way to halve a recipe without the cake turning out dry or greasy.
Roasting vegetables
Roasting a tray of vegetables with 1/4 cup of coconut oil takes about 54.5 g. Weighing the oil keeps the vegetables coated without pooling in the tray, and it keeps the calories honest too.
When this conversion matters most
This conversion matters most in baking, where coconut oil controls tenderness, spread and flakiness all at once. A cake, a cookie or a pastry has no room for a 10 g error, and the smaller the recipe the bigger the error looks as a percentage. It also matters when you are following a recipe from another country, because most of the world bakes in grams and a cup is an American habit. Converting to grams lets you use any recipe from any source with the same confidence.
Common mistakes with coconut oil
- Scooping a solid fat into a cup. Scooping leaves air pockets, so a cup of coconut oil can be 10 g light. Pack it firmly or, better, weigh 109 g on a scale.
- Measuring melted fat by the cup. Melted fat takes up less volume than solid fat, so a cup of melted coconut oil weighs more than a cup of solid coconut oil. Measure in the state the recipe specifies, or weigh it.
- Trusting a cup for a half-cup. Small measures amplify error: a heaped half-cup can be 10 g heavy. Weighing 109 g removes the problem entirely.
- Forgetting the fat is also liquid. In baking, coconut oil counts towards the richness of the batter, so adding it on top of the full measure makes a cake greasy. Use the weight in the recipe, not a guess.
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 good storage is not just about freshness, it is about measurement accuracy too. If a container 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 1/2 cup of coconut oil?
1/2 cup of coconut oil weighs 109 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 pouring the ingredient into a liquid measuring jug on a flat surface and reading the level at eye level. Liquids level themselves, so there is no spooning or levelling involved, and the weight follows directly from the volume and the density. That gives the closest result to 109 g per half-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.
Can I swap coconut oil for butter cup-for-cup?
Not reliably. Different fats weigh different amounts per cup and behave differently in baking, so a cup-for-cup swap changes the recipe. Swap by weight instead: 1/2 cup of coconut oil is 109 g, so use the same weight of the other fat and expect a slightly different flavour and texture. Butter also contains water and milk solids, which oils and shortening do not.
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.
Does 1/2 cup of coconut oil always weigh 109 g?
No. Temperature, brand and how firmly a solid fat is packed all shift the weight by a few grams. The 109 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.
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.
