1 Tablespoon of Salt in Grams by Brand

A tablespoon of table salt weighs 18 grams. Morton kosher salt weighs 16 grams per tablespoon. Diamond Crystal weighs only 8 grams, less than half as much as table salt.

1 Cup Salt in Grams

1 cup salt in grams is 292 grams for table salt, according to USDA data. Using 18 grams per tablespoon gives a close 288 grams. That is about 10.3 ounces, and 1 pound of table salt fills about 1 1/2 cups.

Swapping Table Salt and Kosher Salt

Morton Salt lists 1 teaspoon of table salt as equal to 1 1/4 teaspoons of its kosher salt. For 1 cup of table salt, use 1 1/4 cups of Morton kosher salt. Diamond Crystal needs more than twice the volume of table salt, so weigh it when you can.

Baking Soda and Baking Powder in Grams

Baking soda is denser than baking powder, so a teaspoon weighs more. King Arthur Baking lists 1/2 teaspoon of baking soda at 3 grams and 1 teaspoon of baking powder at 4 grams. The chart below also includes instant yeast for quick reference.

1 Tsp Baking Soda in Grams

1 tsp baking soda in grams is 6 grams, based on the King Arthur value of 3 grams per 1/2 teaspoon. Half a teaspoon is 3 grams, and a tablespoon is 18 grams. Baking soda weighs about the same per spoon as table salt.

1 Tsp Baking Powder in Grams

One teaspoon of baking powder weighs 4 grams. A tablespoon weighs 12 grams, and 3 teaspoons equal 1 tablespoon. 10 grams of baking powder is 2 1/2 teaspoons.

Baking Soda and Baking Powder Are Not the Same

Baking soda is pure sodium bicarbonate and needs an acid in the recipe to work. Baking powder is baking soda mixed with an acid and a starch, as Arm and Hammer explains. Arm and Hammer says baking soda is about 3 to 4 times as strong as baking powder.

Yeast in Grams and Teaspoons

One packet of dry yeast holds 1/4 ounce, which is 7 grams or 2 1/4 teaspoons, according to Red Star Yeast. Red Star also notes that active dry yeast and instant yeast can be swapped for each other. King Arthur Baking lists instant yeast at 9 grams per tablespoon.

Fresh Yeast to Instant Yeast Conversion

Red Star counts a 0.6 ounce piece of fresh cake yeast as equal to one 1/4 ounce packet of dry yeast. Purdue Extension gives the same match. By weight, that is about 17 grams of fresh yeast for every 7 grams of dry yeast.

7g Dry Yeast to Teaspoons

7 grams of dry yeast is 2 1/4 teaspoons, or one packet. 12 grams of yeast is about 4 teaspoons. One tablespoon of instant yeast weighs 9 grams.

Grams of Salt, Baking Soda and Baking Powder to Teaspoons

Recipes from bakeries and other countries list these small amounts in grams. Divide the grams by the weight of 1 teaspoon to get teaspoons. Divide by 3 more to get tablespoons.

10g, 12g and 30g of Salt in Spoons

10 grams of table salt is about 1 2/3 teaspoons, or a little over 1/2 tablespoon. 12 grams is exactly 2 teaspoons. 30 grams is about 1 2/3 tablespoons.

How to Convert These Ingredients

Each ingredient has its own teaspoon weight. Use 6 grams for table salt and baking soda, 4 grams for baking powder and 3 grams for instant yeast. Multiply teaspoons by that number to get grams, or divide grams by it to get teaspoons.

Spoons to Grams

For 1 1/2 teaspoons of baking soda, 1.5 × 6 = 9 grams. For 2 teaspoons of baking powder, 2 × 4 = 8 grams. For 2 tablespoons of table salt, 2 × 18 = 36 grams.

Grams to Spoons

For 15 grams of salt, 15 ÷ 6 = 2.5 teaspoons. For 10 grams of baking powder, 10 ÷ 4 = 2.5 teaspoons. For 20 grams of baking soda, 20 ÷ 6 = 3.3 teaspoons, or about 1 tablespoon.

Tips for Measuring Small Amounts

A gram or two of salt or soda can change a whole bake. These habits keep spoon measures close to the chart. They matter most for bread, biscuits and cookies.

  • Level every spoon. Sweep the top flat with the back of a knife.
  • Check the salt brand. Table salt and kosher salt are not equal by the spoon.
  • Check the date. Use baking powder and baking soda before the date on the box.
  • Do not swap soda and powder 1 to 1. Use the swap table above instead.
  • Weigh yeast for big batches. A scale is more exact than spoons for bread.
