How the formula works
A US teaspoon is exactly 4.92892159375 milliliters. Each ingredient has a density in grams per milliliter. The converter first computes grams per teaspoon, then converts:
For example, all-purpose flour has a density of 0.5072 g/mL, giving 2.5 g per tsp. So 10 grams of flour / 2.5 g per tsp = 4 teaspoons.
