1/2 Cup Coconut Milk in Grams
1/2 cup of coconut milk weighs 120 g (poured, USDA). Rich liquid pressed from grated coconut flesh; shake canned coconut milk before using. 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.
Rich liquid pressed from grated coconut flesh; shake canned coconut milk before using. It is used for curries, soups, smoothies and dairy-free baking. 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 milk beats measuring it in cups
Half a cup is the amount most recipes call for when a liquid is a main ingredient rather than a splash: a soup, a sauce, a cake batter or a marinade. coconut milk is mostly water by weight, so 120 g for 1/2 cup is close to the weight of water, but the small difference matters in baking, where liquid decides hydration and therefore texture. The 120 g figure on this page is the standard for coconut milk measured poured from USDA, so it gives you a fixed number to work from whether you are cooking a weekday dinner or a celebration cake. Once you know the weight, scaling a recipe up or down becomes simple arithmetic instead of a gamble.
Coconut Milk cups to grams conversion table
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 60 g |
| 1/3 cup | 80 g |
| 1/2 cup | 120 g |
| 2/3 cup | 160 g |
| 3/4 cup | 180 g |
| 1 cup | 240 g |
| 1 1/2 cups | 360 g |
| 2 cups | 480 g |
| 3 cups | 720 g |
One tablespoon of coconut milk weighs about 15 g, and one teaspoon about 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 120 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 240 g per cup figure is USDA, and the confidence in the value is medium. 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.
Because coconut milk is measured poured, the weight per cup is stable from one kitchen to the next, and the 120 g figure for half a cup is a reliable default. Small differences in brand or temperature shift it by only a gram or two, which is far below the threshold that changes a recipe.
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 bread dough
A bread recipe using 1/2 cup of coconut milk needs 120 g, and the liquid must be weighed precisely because hydration decides whether the dough is workable or sticky. Too much and the loaf spreads; too little and it turns dense. Weigh it and the dough will feel right from the first mix.
Scaling up a batch of sauce
A sauce that starts with 2 cups of coconut milk needs 480 g. At that scale a jug error compounds badly, and a thin sauce is hard to rescue, so weighing the full amount on a scale is the only sensible approach.
A dressing for a salad
A dressing calling for 1/3 cup of coconut milk needs about 80 g. The liquid balances oil and acid in the dressing, and weighing it keeps the balance right even when you scale the recipe for a crowd.
When this conversion matters most
The weight matters whenever coconut milk is doing structural work rather than just adding moisture. In a bread dough the liquid decides hydration; in a custard it decides whether the set is silky or rubbery; in a sauce it decides thickness. In a glass to drink, by contrast, a gram or two either way is invisible, so save the scale for the recipes where it counts and pour freely where it does not.
Common mistakes with coconut milk
- Pouring over the mixing bowl. Spilling a little extra into the bowl is easy and invisible. Pour over the sink, or weigh directly into the bowl on a tared scale.
- Rounding down to save time. Rounding 120 g to a neat number feels tidy but is a real error in a small bake. Keep the real figure; the scale does the work for you.
- Using a cold liquid when the recipe wants warm. Temperature changes how a liquid behaves in a dough, even though the weight barely changes. Warm it first if the recipe says so, then weigh 120 g.
- Measuring sticky liquids in a jug. Thick liquids cling to the jug and a spoonful stays behind. Weigh them instead, pouring straight into the bowl on a tared scale.
Storage and handling
Refrigerate after opening; use within 3 days. Keeping coconut milk 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 milk?
1/2 cup of coconut milk weighs 120 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 milk 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 120 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.
How do I measure coconut milk without a scale?
Pour it into a liquid measuring jug on a flat surface and read the meniscus at eye level at the 1/2-cup line. That is the correct method for liquids, and it is reasonably accurate, but a scale reading 120 g is more reliable, especially for small amounts.
What is coconut milk used for?
Curries, soups, smoothies and dairy-free baking. Rich liquid pressed from grated coconut flesh; shake canned coconut milk before using.
Does 1/2 cup of coconut milk always weigh 120 g?
Almost. Liquids are far more consistent than dry ingredients: brand and temperature shift the weight by only a gram or two. The 120 g figure is the standard USDA value for coconut milk measured poured, and it is a reliable default.
How should I store coconut milk?
Refrigerate after opening; use within 3 days. 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.
