How to Convert Tablespoons to Teaspoons
1 tablespoon = 3 teaspoons (US/UK/Canada). Multiply tablespoons by 3 to get teaspoons. So 2 tbsp = 6 tsp. Australian: 1 Australian tbsp (20 ml) = 4 teaspoons. Outside Australia, the 3:1 ratio is universal.
Useful when scaling down a recipe that uses tablespoons but you want spoon-level precision, or when out of measuring tablespoons but have teaspoons available. 1 tbsp baking powder = 3 tsp baking powder - same amount, just different spoon.

Frequently Asked Questions
Why are tbsp 3 tsp?
Historical convention from the metric/customary system standardisation. The relationship goes back to apothecary measurements where 60 grains = 1 dram, 8 drams = 1 ounce, etc. The 3:1 tbsp:tsp ratio fits the broader hierarchy.
Are tbsp and tsp interchangeable for small amounts?
Mathematically yes (3 tsp = 1 tbsp). Physically using a tbsp scoop for 3 tsp of an ingredient is fine. The reverse (using a tsp scoop 3 times for 1 tbsp) works but takes longer and increases small measurement errors.
