Formula & worked example
1 tablespoon = 3 teaspoons. 2 tablespoons = 6 teaspoons, and 4 tablespoons (a quarter-cup) = 12 teaspoons.
Limitations — read this before you rely on it
The 3-to-1 rule holds across systems, but the absolute size of a tablespoon differs (US 14.79 ml, Imperial 17.76 ml, Australian metric 20 ml) — so the rule converts counts, not millilitres, across systems.
