Science & measurement
Measurement system: US/Imperial length-derived → US customary

Convert cubic inch (in³) → US teaspoon (US tsp)

1 in³ equals 3.32467532468 US tsp. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

cubic inch and US teaspoon 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 in³ = 3.32467532468 US tsp · 10 in³ = 33.2467532468 US tsp.

3.32467532468 US tsp
