Measurement system: US customary → US customary

Convert US teaspoon (US tsp) → US tablespoon (US tbsp)

1 US tsp equals 0.333333333333 US tbsp. The name of a customary unit matters: US liquid and Imperial units are not interchangeable. US teaspoon (US tsp) is shown explicitly so a reader can recognize the term used in recipes and measuring tools.

Why the distinction matters

US teaspoon and US tablespoon belong to measurement conventions that may look familiar but are not always equivalent across countries. Mendeleev.com therefore keeps the system name next to the abbreviation and calculates from defined conversion factors rather than rounded kitchen rules.

Example

1 US tsp = 0.333333333333 US tbsp · 10 US tsp = 3.33333333333 US tbsp.

0.333333333333 US tbsp
