Table Salt:
Grams to Cups
By Stefan Ulrich · Last updated
Table salt weighs 288 grams per cup, but the critical measurement is per teaspoon: 1 teaspoon = 6 grams. The reason salt is one of the most dangerous ingredients to convert by volume is that different salt types have wildly different weights per teaspoon — kosher salt can be half the weight of table salt for the same volume.

About Table Salt
The salt conversion problem is simple to state and devastating to get wrong: 1 teaspoon of table salt (6 g) is NOT the same as 1 teaspoon of kosher salt. Morton kosher salt weighs about 5 g per teaspoon. Diamond Crystal kosher salt weighs only 3 g per teaspoon — half the saltiness of table salt for the same volume measure.
This means a recipe that calls for '1 teaspoon salt' without specifying the type can produce dramatically different results depending on which salt you grab. Most professional recipe developers now specify the brand of kosher salt they use, or provide weight measurements.
For baking, the conversion chart is essential: - 1 tsp table salt = 6 g - 1 tsp Morton kosher salt = 5 g - 1 tsp Diamond Crystal kosher salt = 3 g - 1 tsp fine sea salt = 5–6 g - 1 tsp flaky Maldon sea salt = 3–4 g
When a recipe specifies 'salt' without qualification, American recipes almost always mean table salt or Morton kosher salt. If you're using Diamond Crystal, use about 1.5–2x the volume listed.
Tips for measuring Table Salt
- Table salt: 6 g/tsp. Morton kosher: 5 g/tsp. Diamond Crystal: 3 g/tsp.
- When in doubt, use weight — it eliminates the salt type problem entirely.
- For bread: 1.8–2% salt by weight of flour is the professional standard.
- You can always add salt later — you cannot remove it.
Common mistakes
- Using Diamond Crystal quantities when recipe specifies Morton (half the salt)
- Using table salt quantities with kosher salt volumes (over-salting)
Frequently Asked Questions
- How many grams in a cup of Table Salt?
- 1 cup of Table Salt weighs 288 grams — the standard used in most American recipes. Use the converter above for any other amount.
- How many grams is 1 tablespoon of Table Salt?
- 1 tablespoon of Table Salt weighs about 18 grams. The full table above lists every common cup fraction.
- What's the most common mistake when measuring Table Salt?
- Using Diamond Crystal quantities when recipe specifies Morton (half the salt). Weighing on a kitchen scale avoids it entirely.
- Does Table Salt need to be levelled in the cup?
- Yes — spoon table Salt in and sweep a straight edge across the top. Scooping or tapping compacts it and changes the weight.
