How Much Is 1 Teaspoon of Rolled Oats in Grams?
1 teaspoon of rolled oats weighs 1.88 g. This is based on rolled oats having a density of 90g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 teaspoon.
