3/4 Cup Coffee in Grams
3/4 cup of coffee weighs 177.8 g (poured, USDA). Brewed black coffee, essentially flavoured water. All the figures on this page are approximate conversions based on the USDA value of 237 g per cup, so when a recipe really matters, verify with a kitchen scale.
It is used for drinking, tiramisu, chocolate cake and sauces. 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.
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 237 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.
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.
Coffee cups to grams conversion table
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 59.2 g |
| 1/3 cup | 79 g |
| 1/2 cup | 118.5 g |
| 2/3 cup | 158 g |
| 3/4 cup | 177.8 g |
| 1 cup | 237 g |

| 2 cups | 474 g |
| 3 cups | 711 g |
One tablespoon of coffee weighs about 14.8 g, and one teaspoon about 4.9 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 177.8 g is the one to use when a recipe calls for 3/4 cup.
When this conversion matters most
This conversion matters most in chocolate cake and tiramisu, where brewed coffee is a flavouring liquid that has to be in proportion. In a chocolate cake, coffee deepens the chocolate without adding a coffee taste, but the liquid amount still sets the batter consistency. In tiramisu, the coffee amount decides whether the ladyfingers hold their shape or dissolve. Brewed black coffee weighs 237 g per cup, the same as water, so 3/4 cup is 177.8 g. For drinking, the exact weight is irrelevant. One practical point: use cooled coffee in a cake batter, because hot coffee can start cooking the eggs and change the texture.
Worked examples
A chocolate cake that uses coffee instead of water
A chocolate cake calling for 3/4 cup of brewed coffee needs 177.8 g. Coffee deepens the chocolate flavour without making the cake taste of coffee, which is why so many chocolate cake recipes use it instead of water. Weighing 177.8 g matters because the liquid amount sets the batter consistency: too much and the cake sinks, too little and it turns dry. Brew the coffee, let it cool, and weigh it into the batter.
A tiramisu for a dinner party
A tiramisu that uses 3/4 cup of brewed coffee needs 177.8 g, cooled and mixed with a little liqueur for dipping the ladyfingers. The coffee amount decides whether the ladyfingers are soaked through or turn to mush: too much and the dessert collapses, too little and the layers stay dry. Weighing 177.8 g and dipping each ladyfinger quickly, rather than soaking it, keeps the layers distinct.
A coffee glaze for a bundt cake
A glaze recipe that calls for 3/4 cup of brewed coffee needs 177.8 g, reduced with sugar until it coats a spoon. The coffee gives the glaze its flavour and its colour, and the amount decides whether the glaze sets or runs off the cake. Weighing the coffee and reducing it by a third gives a glaze thick enough to cling to the bundt ridges.
Common mistakes
The most common mistake is using hot coffee in a cake batter, where it can scramble the eggs and melt the butter before the cake reaches the oven. Let it cool first. A second mistake is using instant coffee granules in place of brewed coffee without dissolving them: the granules do not distribute evenly and the cake tastes bitter in spots. A third mistake is soaking ladyfingers in tiramisu instead of dipping them quickly, which turns the layers to mush no matter how carefully the coffee was weighed.
If you do not have a kitchen scale, measure with tablespoons instead of a cup: 3/4 cup is 12 level tablespoons, and levelling each spoonful separately keeps the total far closer to the true weight than a single cup measure. For thick ingredients like sour cream or cream cheese, press the spoonful in firmly and level the top; for liquids, fill the spoon on a flat surface. This method works well for cooking, where a few grams either way do not matter, but for baking, a scale is the better investment: it removes the guesswork entirely and makes every recipe repeatable.
Why weighing 3/4 cup of coffee beats measuring it in cups
Liquid is the ingredient that sets the hydration of a recipe, and 3/4 cup is an amount that appears in cakes, dressings, and braises all the time. Weighing it matters because a measuring jug is easy to misread: the curved surface of the liquid makes the level hard to see, and reading it from above makes it look lower than it is. A jug measure can be 10 g or more off, which is enough to change a batter from thick to thin. Weighing removes that whole source of error, and it is faster than pouring, checking, and pouring again.
Storage
Drink fresh; refrigerate leftovers up to 1 week. Brewed black coffee, essentially flavoured water. It is used for drinking, tiramisu, chocolate cake and sauces. 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.
Frequently asked questions
How many grams is 3/4 cup of coffee?
3/4 cup of brewed black coffee weighs 177.8 g, poured, using the USDA value of 237 g per cup. The figure is approximate, so verify with a kitchen scale when the recipe matters, especially for baking and tiramisu.
Does coffee weigh the same as water?
Yes, for practical purposes. Brewed black coffee is essentially flavoured water, so a cup weighs 237 g, the same as water, and 3/4 cup is 177.8 g. Coffee with milk or sugar weighs slightly more, but the difference is a gram or two.
How many tablespoons is 3/4 cup of coffee?
3/4 cup is 12 tablespoons, and one tablespoon of brewed coffee weighs about 15 g. That gives roughly 177.8 g for the full 12 tablespoons. Weighing the coffee into a jug on the scale is the most accurate method.
Can I use instant coffee instead of brewed coffee?
Yes, but dissolve it first: mix about two teaspoons of instant coffee into 177.8 g of hot water, then let it cool. Undissolved granules will not distribute evenly in a batter and can taste bitter. The weight of the brewed liquid stays 177.8 g for 3/4 cup.
Should the coffee be hot or cold in a cake batter?
Cool it first. Hot coffee can scramble the eggs and melt the butter before the cake reaches the oven, which changes the texture. Brew the coffee, let it cool to room temperature, then weigh 177.8 g into the batter.
