Convert salt grams to cups, tablespoons, and teaspoons—or reverse cups to grams—with separate table salt, coarse kosher salt, and custom calibrations.

Salt weight per cup varies with crystal shape, brand and packing. Presets scale rounded published spoon weights; a scale and your own level-cup measurement give a more specific conversion.

Grams of Salt to Cups Formula

Use R, the measured or assumed grams per US customary cup, to convert between salt weight and volume. The presets scale rounded spoon-weight references and are approximate.

cups = g / R
g = cups × R
  • US cup = 236.588 mL
  • Metric cup = 250 mL
  • Table salt: about 288 g per cup, derived from King Arthur’s 18 g per tablespoon
  • Morton kosher salt: about 230.4 g per cup, scaled from the rounded product label of 1.2 g per ¼ teaspoon
  • Diamond Crystal kosher salt: King Arthur lists 8 g per tablespoon (about 128 g per cup); use the custom calibration for this salt
  • Fine sea salt: use a measured custom calibration; there is no universal grams-per-cup value
  • Coarse sea salt: crystal size and packing require a salt-specific custom calibration

* Uses the approximate table-salt calibration of 288 g per US customary cup. Actual results vary by brand and packing.

How do you convert grams of salt to cups? Choose a calibration R in grams per cup, then compute cups = grams ÷ R. The calculator uses US customary cups (236.5882365 mL), not metric or labeling cups.

How do you convert cups of salt to grams? Multiply cups by R: grams = cups × R. For this US customary system, 1 cup = 16 tablespoons = 48 teaspoons.

Example Problem

Convert 100 grams of Morton kosher salt to US cups.

Use cups = grams ÷ R, with the approximate Morton label-based calibration R = 230.4 g/cup.

cups = 100 ÷ 230.4 ≈ 0.434 cups (US)
