Also known as koshering salt, flake salt.
1 ounce of kosher salt = 0.22 US cups. That's based on a 128 g per cup baseline. Because kosher salt can shift with brand and measuring style, weighing is usually more accurate than measuring by volume.

What the sources say kosher salt weighs
Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.
| Source | Listed measure | Weight |
|---|---|---|
| King Arthur Baking | 1 tbsp (Diamond Crystal) | 8 g |
| King Arthur Baking | 1 tbsp (Morton coarse) | 16 g |
| Morton (product label) | 1/4 tsp (coarse kosher)Nutrition-facts serving size on Morton's own product page. | 1.2 g |
CupOrGram standardizes on 128 g per cup (8 g per tablespoon, 2.7 g per teaspoon) and uses that single value on every page — how we reconcile the sources.
Why this conversion varies
Kosher Salt can vary by brand and measuring style.
- Kosher Salt may settle, compress, or pour differently based on handling.
- kosher salt can shift with temperature and ingredient texture.
- This page uses a consistent 128 g per cup baseline for repeatable conversions.
Why this conversion matters
Kosher Salt can behave differently by brand and handling. Converting kosher salt with a consistent baseline gives you a more dependable starting point for scaling recipes.
Practical baking use
Coarse, flaky salt with no anti-caking agents. The one ingredient where the brand changes the measurement: Diamond Crystal weighs about half as much as Morton for the same spoon. Use this conversion as a practical starting point for scaling recipes with kosher salt.
- If consistency matters, verify with a small test batch first.
- Use weight-based measurements when precision is critical.
FAQ
How much is 1 ounce of kosher salt in US cups?
1 ounce of kosher salt is 0.22 US cups using a 128 g per cup baseline.
Is 8 oz of kosher salt the same as 1 cup?
1.8 cups — 8 oz by weight of kosher salt is not 1 US cup. A cup of kosher salt weighs 128 g (4.5 oz). Ounces on this page are weight, not fluid ounces — the "8 oz = 1 cup" rule only holds for water-like liquids.
Is it better to weigh kosher salt for baking?
Usually yes. Weight-based measuring reduces shifts from brand and measuring style, so your results are more repeatable.

Recipe Context for Kosher Salt
For chemical leavening: small weight changes alter rise and browning.
For quick breads: over-leavening can cause collapse after oven spring.
For cookies: balance leavening with acid source for predictable spread.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Expired leaveners can underperform even when measured correctly.
Brand Variance Example
Baseline on this page: 1 cup kosher salt = 128g. Real-world range can shift by about 6% because fine powders and leaveners settle during storage, changing cup density.
Example for 2 cups: baseline 256g, common range 240g-272g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
