Does 2 teaspoons equal 1 gram?

Explanation:

There are 28.35 grams in 1 ounce. Since there are 2 tablespoons in 1 ounce, 1 tablespoon contains 14.175 grams. Since there are 3 teaspoons in 1 tablespoon, 1 teaspoon contains 14.175 / 3 = 4.725 grams. Therefore, 2 teaspoons contain 2 x 4.725 = 9.45 grams.

So, 2 teaspoons does not equal 1 gram.
