The Tsp to Tablespoon Formula
Since 1 tablespoon equals 3 teaspoons, divide teaspoons by 3 to get tablespoons.
The Exact Calculation
For 1 tsp: 1 / 3 = 0.333 tbsp. For 3 tsp: 3 / 3 = 1 tbsp. For 6 tsp: 6 / 3 = 2 tbsp. The ratio is exact by US definition.
In milliliters, 1 tsp is about 4.93 ml and 1 tbsp is about 14.79 ml, and 14.79 / 4.93 = 3, confirming that 3 tsp make 1 tbsp.
The Metric Exception
The Australian metric tablespoon is 20 ml and the metric teaspoon is 5 ml, so there 4 tsp make 1 tbsp. The 3-to-1 ratio is for US and UK spoons.
What the Numbers Look Like
A dose of 1 tsp is 0.333 tbsp; 2 tsp is 0.667 tbsp; 3 tsp is exactly 1 tbsp. Baking soda or spice amounts in tsp convert cleanly this way.
