One US teaspoon (4.93 ml) of rolled oats weighs 1.69 grams, from USDA FoodData Central, SR Legacy entry 173904 “Cereals, oats, regular and quick, not fortified, dry”, portion “1 cup” = 81 grams, and 1 US cup = 48 US teaspoons.

The other way round: how many teaspoons a weight fills
This page starts from teaspoons and answers in grams. The opposite question — how many teaspoons a weight from a recipe fills — is what the grams to teaspoons converter is for. Both read the same USDA weights, so their numbers agree: 100 grams of rolled oats is 59.3 teaspoons there.
