1 Cup Salt in Millilitres

1 cup of salt is 236.6 ml and weighs 288 g (spooned and levelled, King Arthur Baking). Fine-grained salt; the default seasoning salt. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale.

Dry spices and seasonings are the ingredients where a cup is almost never the right measure — a whole cup of a ground spice is an enormous amount — yet recipes written in cups still need converting, and the weight per cup varies enormously. One cup is always 236.6 ml, but the grams run from under 90 g to nearly 290 g depending on the ingredient. This page gives you both figures.

Why millilitres and grams are two different answers

Millilitres measure space and grams measure mass, and for dry spices the gap between them is dramatic. One US cup is 236.6 ml of space, but the weight of that space runs from under 90 g for a light, fluffy powder to nearly 290 g for fine salt. The difference is density and grind: fine powders settle heavily, coarse ones trap air, and a crystal like salt packs far more tightly than a ground spice. That is why recipes almost never call for a cup of spice, and why the gram column of the table is the useful one when they do. Use millilitres for a jug, grams for a scale, and never swap one spice's weight for another's.

Salt cups to millilitres conversion table

Cups Millilitres Grams Tablespoons
1/4 cup 59.1 ml 72 g 4 tbsp
1/3 cup 78.9 ml 96 g 5.3 tbsp
1/2 cup 118.3 ml 144 g 8 tbsp
2/3 cup 157.7 ml 192 g 10.7 tbsp
3/4 cup 177.4 ml 216 g 12 tbsp
1 cup 236.6 ml 288 g 16 tbsp
2 cups 473.2 ml 576 g 32 tbsp
3 cups 709.8 ml 864 g 48 tbsp
4 cups 946.4 ml 1152 g 64 tbsp

The table covers the amounts recipes actually ask for, from a quarter cup up to four cups. One tablespoon of salt is about 18 g and 14.8 ml, which is handy when a recipe calls for a spoonful rather than a cup: divide the cup weight by 16 and you have the tablespoon weight. Remember that the millilitre column never changes — 1 cup is always 236.6 ml — while the gram column depends on the King Arthur Baking density of 288 g per cup, measured spooned and levelled. If your recipe was written in grams, read the gram column; if it was written in cups or millilitres, read the millilitre column.

How much is 100 ml, 250 ml and 500 ml of salt?

Millilitres Cups Grams
100 ml 0.4 cups 121.7 g
250 ml 1.1 cups 304.3 g
500 ml 2.1 cups 608.6 g

Recipes written in metric units often call for round millilitre amounts rather than cups, so this table bridges the two. 250 ml of salt is just over a cup — 1.1 cups — and weighs 304.3 g, while 500 ml is 2.1 cups and 608.6 g. A standard measuring jug usually has both millilitre and cup markings, so you can pour to either scale, but the gram column is the one to use on a scale. Note that 100 ml is 0.4 of a cup, which is why metric recipes rarely line up neatly with cup measures.

Worked examples

Seasoning every dish calling for 2 cups of salt

A seasoning every dish recipe that calls for 2 cups of salt needs 473.2 ml, which weighs 576 g. That is the figure to measure: pour 473.2 ml into a liquid jug, or weigh 576 g straight into the bowl. Because salt is used for seasoning every dish and controlling yeast in bread. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 576 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.

Controlling yeast in bread calling for half a cup of salt

A controlling yeast in bread recipe that calls for half a cup of salt needs 118.3 ml, which weighs 144 g. That is the figure to measure: pour 118.3 ml into a liquid jug, or weigh 144 g straight into the bowl. Because salt is used for seasoning every dish and controlling yeast in bread. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 144 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.

Seasoning every dish calling for 3 cups of salt

A seasoning every dish recipe that calls for 3 cups of salt needs 709.8 ml, which weighs 864 g. That is the figure to measure: pour 709.8 ml into a liquid jug, or weigh 864 g straight into the bowl. Because salt is used for seasoning every dish and controlling yeast in bread. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 864 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.

Scaling works the same way in both directions. Double the recipe and 3 cups becomes 1419.6 ml, or 1728 g. Halve it and you need 354.9 ml, or 432 g. When you scale, always scale by weight if the original recipe was written in grams, and by volume if it was written in cups — mixing the two mid-recipe is how scaling errors creep in. And remember that a US cup is 236.6 ml, while a metric cup is 250 ml: if you are following a recipe from Australia, New Zealand or South Africa, one cup means 250 ml, which is 304.3 g of salt, not 288 g. Check which cup your recipe uses before you convert.

How the weight was measured

Spooned and levelled means the ingredient is spooned loosely into the measuring cup and the top is swept flat with a straight knife. The ingredient is never scooped with the cup itself and never pressed down, because both of those habits pack extra material into the cup and push the weight up.

The source for the 288 g figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking 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. Fine table salt packs at 288 g per cup (18 g per tablespoon). Kosher salt is far lighter: Diamond Crystal is about 128 g per cup and Morton about 256 g - never swap them cup-for-cup. This page follows the King Arthur Baking value of 288 g per cup, measured spooned and levelled, rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.

Common mistakes with salt

  • Scooping the spice out of the jar. Dipping the cup into the jar packs the powder. Spoon it in and level it off, or the weight creeps up with every scoop.
  • Measuring over a steaming pot. Steam clumps ground spices and adds moisture weight. Measure away from the heat, then add the spice to the pot.
  • Swapping one spice's weight for another. A cup of salt weighs more than three times a cup of ground ginger. Never use one spice's conversion for a different spice.
  • Trusting an old, settled jar. A jar that has sat for months settles denser at the bottom. Stir or shake it before measuring, or weigh the spice.

Storage and handling

Dry cupboard, indefinitely. Fine-grained salt; the default seasoning salt. Keeping salt 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 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. salt is used for seasoning every dish and controlling yeast in bread. and it is worth keeping a note of the 288 g per cup figure on the container, so the conversion is always to hand.

Frequently asked questions

How many millilitres is 1 cup of salt?

1 cup of salt is 236.6 ml. That is the fixed volume of one US customary cup, and it is the same for every ingredient on this site: the cup does not change, only the weight inside it does. If your recipe is from a metric country, note that a metric cup is 250 ml, which is a different measure — check which cup the recipe means before converting.

How many grams is 1 cup of salt?

1 cup of salt weighs 288 g, measured spooned and levelled according to King Arthur Baking. That is the figure the conversion table on this page is built on, and it is the value to use when a recipe gives weights. All the gram figures here are approximate, so when a bake really matters, verify with a kitchen scale.

Is 1 cup of salt always 236.6 ml?

Yes, as long as the recipe means a US customary cup. One US cup is 236.6 ml by definition, whatever is in it. The confusion comes from the metric cup, which is 250 ml, and from the old imperial cup. If a recipe does not say which cup it uses, a US recipe almost always means the 236.6 ml cup, while a recipe from Australia or New Zealand usually means the 250 ml metric cup.

How do I measure salt without a scale?

Spooned and levelled means the ingredient is spooned loosely into the measuring cup and the top is swept flat with a straight knife. The ingredient is never scooped with the cup itself and never pressed down, because both of those habits pack extra material into the cup and push the weight up. That gives the closest result to 288 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 salt weigh the same as water?

No. One cup of salt weighs 288 g, which is heavier than water, which weighs 237 g per cup — 51 g heavier, to be exact. That is why you cannot convert salt by assuming a millilitre weighs a gram: for water the shortcut works, but for salt it would be off by 51 g per cup, and the error grows with the size of the recipe.
