How this works
Water has a density of about 1.000 g/mL (si definition). That means 1 mL of water weighs 1.000 grams.
Teaspoons = grams × 0.2029
Note: By definition at 4°C. Within 0.5% across cooking temperatures.
Why a cup of water doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of water can vary by 10-20% in weight depending on how it's measured: spooned vs scooped, packed vs loose, sifted vs unsifted. The density figure used here matches the most common published recipe conventions, but if you're after baking precision, weighing on a kitchen scale is more accurate than measuring by volume.
