1/2 Cup Salt in Grams
1/2 cup of salt weighs 144 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.
Fine-grained salt; the default seasoning salt. It is used for seasoning every dish and controlling yeast in bread. 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 salt beats measuring it in cups
Spices and salt are measured in tiny amounts, which is exactly why their weight matters so much. 1/2 cup of salt weighs 144 g, and in a recipe that calls for half a cup of a spice, a spoonful too much can overwhelm the dish while a spoonful too little leaves it flat. Cups are a poor way to measure a fine powder: it settles, it packs, and the same cup can weigh differently from one day to the next depending on humidity. Weighing 144 g on a scale removes all of that, and for a spice it is the difference between a dish that is seasoned and a dish that is ruined.
Salt cups to grams conversion table
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 72 g |
| 1/3 cup | 96 g |
| 1/2 cup | 144 g |
| 2/3 cup | 192 g |
| 3/4 cup | 216 g |
| 1 cup | 288 g |
| 1 1/2 cups | 432 g |
| 2 cups | 576 g |
| 3 cups | 864 g |
One tablespoon of salt weighs about 18 g, and one teaspoon about 6 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 144 g is the one to use when a recipe calls for half a cup.
How the weight was measured
Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight.
The source for the 288 g per cup 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. 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 big batch of chilli
A chilli recipe calling for 1/2 cup of salt needs 144 g. Weighing the spice means the heat and flavour are exactly right, because a spice is concentrated and a spoonful too much changes the whole pot. If the recipe is doubled for a crowd, use 288 g for 1 cup.
Halving a spice rub
Halving a rub that asks for 1 cup of salt leaves you with 1/2 cup, or 144 g. A half-cup measure of a fine powder is notoriously inaccurate because it settles and packs, so weighing 144 g is the reliable way to halve a recipe without the rub turning out bland or overpowering.
A small batch of baking spice
A baking recipe needing 1/4 cup of salt takes about 72 g. Weighing such a small amount is far more reliable than eyeballing a quarter-cup measure, and it keeps the spice from overwhelming the bake.
When this conversion matters most
This conversion matters most in bulk cooking and baking, where salt is used in large amounts and a small percentage error becomes a large absolute error. A pot of chilli, a tray of spiced buns or a jar of pickling spice has no room for a 10 g error, because the spice is the dominant flavour. It also matters when you are following a recipe from another country, because most of the world cooks 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 salt
- Scooping a fine powder. Scooping compresses a powder, so a cup of salt can be 10 g heavy. Spoon it into the cup and level it off, or better, weigh 144 g on a scale.
- Measuring over the pot. Steam rises into the spice jar and clumps the powder, which changes the weight per cup. Measure away from the heat, or weigh 144 g on a scale.
- Trusting a cup for a half-cup. Small measures amplify error: a heaped half-cup can be 10 g heavy. Weighing 144 g removes the problem entirely.
- Using an old spice. Old spices lose potency, which tempts you to add more. Check the storage note on this page and replace stale salt instead of over-measuring it.
Storage and handling
Dry cupboard, indefinitely. 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 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 salt?
1/2 cup of salt weighs 144 g, measured spooned and levelled according to King Arthur Baking. 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 salt without a scale?
Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. That gives the closest result to 144 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 salt for another spice cup-for-cup?
Not reliably. Different spices weigh different amounts per cup and have very different flavours, so a cup-for-cup swap changes the recipe. Swap by weight instead: 1/2 cup of salt is 144 g, so use the same weight of the other spice only if the flavours are genuinely similar, and taste as you go.
What is salt used for?
Seasoning every dish and controlling yeast in bread. Fine-grained salt; the default seasoning salt.
Does 1/2 cup of salt always weigh 144 g?
No. Brand, grind, moisture and how settled the jar is all shift the weight by a few grams. The 144 g figure is the standard King Arthur Baking value for salt measured spooned and levelled, 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 salt?
Dry cupboard, indefinitely. 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.
