1/4 Cup Water in Grams
1/4 cup of water weighs 59.2 g (poured, USDA). The reference liquid for all volume-to-weight conversion. 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.
Why a quarter cup is worth weighing
Quarter-cup amounts show up in small batches, test bakes and single servings — exactly the cooks where there is no margin for error. A large batch forgives a heavy hand; a small one does not, because the same absolute mistake is a far larger share of the total. Weighing a quarter cup is the cheapest insurance in the kitchen: one number on a scale, and the recipe comes out the same every time.
Poured is the method behind the number, and it matters. Water is used for every kind of cooking, baking and drinks. 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: 59.2 g of water is 59.2 g whatever the brand, the humidity or the size of your measuring cup.
Water cups to grams conversion table
| Cups | Grams | Tablespoons |
|---|---|---|
| 1/4 cup | 59.2 g | 4 |
| 1/3 cup | 79 g | 5.3 |
| 1/2 cup | 118.5 g | 8 |
| 2/3 cup | 158 g | 10.7 |
| 3/4 cup | 177.8 g | 12 |
| 1 cup | 237 g | 16 |
| 1 1/2 cups | 355.5 g | 24 |
| 2 cups | 474 g | 32 |
The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of water weighs about 14.8 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 row is the cup weight times the fraction, 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 water, that gives 237 g per cup, and a quarter of that is 59.2 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. One US cup is 236.6 ml, so water weighs 237 g. King Arthur rounds water to 227 g; we use the exact 237 g. That is why this page uses the USDA value of 237 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
Feeding a sourdough starter
A sourdough starter feed for a small jar uses 1/4 cup of water — 59.2 g — stirred into the flour. Starter keepers who weigh their feeds get consistent results, because a starter fed by volume drifts: flour packs, water does not, so the hydration creeps up or down over a week. Weighing 59.2 g of water against the same weight of flour keeps the starter at a steady 100 percent hydration, which is what most recipes assume.
A single-serve mug cake
A mug cake for one person takes 1/4 cup of water, 59.2 g, mixed into the batter — or milk, if you prefer a richer crumb. The water amount decides whether the cake is moist or rubbery, and in a batter this small there is no room for error: 10 g too much and the cake steams instead of baking, 10 g too little and it dries out. Weigh the water into the mug and the cake comes out the same every time.
Cooking rice for one
A single portion of rice cooked by the absorption method uses 1/4 cup of water, 59.2 g, for a small amount of rice — though most cooks scale this up, the ratio is what matters. Water is the one ingredient where cups and grams agree almost exactly, because 1 ml of water weighs 1 g. That makes water the reference point for every other conversion on this site: if your scale says 59.2 g, your quarter cup was exact.
When a quarter cup matters
This conversion matters most when the recipe is small, the ingredient is potent, or the batch is a test. A quarter cup of a strong flavour or a powerful leavener can make or break a dish, and a test batch is only useful if it tells the truth about the full recipe. Weighing the quarter cup makes the test honest and the small batch repeatable.
Water is the simplest conversion in cooking and also the most useful, because it is the reference every other ingredient is measured against. One US cup is 236.6 ml, so a quarter cup is 59.2 g — a figure you can trust to the gram, because water does not pack, settle or vary by brand. The only wrinkle is that some charts round a cup of water to 227 g, the weight of 8 fluid ounces; we use the exact 237 g per cup from USDA, so a quarter cup is 59.2 g.
Scaling a quarter cup up and down
The quarter-cup figure is a building block: every other amount is a simple multiple of it. Doubling a recipe that calls for 1/4 cup means weighing 118.4 g; halving it means 29.6 g, which is 2 tablespoons. A full cup is 237 g, and two cups is 474 g. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 59.2 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 water
- Measuring water in a dry measuring cup. Dry cups are meant to be levelled, not read at eye level, so water measured in one is a guess. Use a liquid jug with a spout, or weigh 59.2 g.
- Assuming all liquids weigh the same as water. Milk is heavier at 244 g per cup, honey far heavier at 336 g. Water is the baseline, not the rule — check each liquid's own figure.
- Pouring freehand from the bottle or jug. A poured quarter cup is easy to overshoot by half, especially with a wide-mouthed bottle. Pour into a jug first, or weigh it.
- Reading a liquid measure at an angle. A jug read from above looks fuller than it is. Set the jug on a flat surface and read it at eye level — or weigh the liquid instead.
Storage and handling
No special storage needed. Keeping water 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 or jar 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 59.2 g — and the next person to cook with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of water?
1/4 cup of water weighs 59.2 g, measured poured according to USDA. That is one quarter of the full-cup weight of 237 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.
How many tablespoons is 1/4 cup of water?
There are 4 tablespoons in a quarter cup, whatever the ingredient. One tablespoon of water weighs about 14.8 g, so 4 tablespoons come to about 59.2 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.
How do I measure 1/4 cup of water without a scale?
Water is measured poured, according to USDA. Pour it into a 1/4-cup liquid measure set on a flat surface, read the level at eye level, and you will be close to 59.2 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good flour and removes the guesswork from every recipe, not just this one.
What is water used for?
Every kind of cooking, baking and drinks. The reference liquid for all volume-to-weight conversion. A quarter cup — 59.2 g — is a common amount in small batches, sauces, dressings and test bakes, which is why this conversion comes up so often.
Is 1/4 cup of water really 59.2 g?
Yes, near enough to exact: one US cup holds 236.6 ml and water weighs 1 g per ml, so a quarter cup is 59.2 g. It is the most reliable conversion on this site. If your scale reads 59 g or 60 g, that is rounding, not an error.
Why do some charts say a cup of water is 227 g?
Because 8 fluid ounces is a weight of about 227 g, and some charts round the cup to 8 ounces by weight. A US cup is actually 236.6 ml, so the correct weight for water is 237 g per cup and 59.2 g per quarter cup. We use the USDA figure.
