Measurement system: US customary → US/Imperial length-derived

Convert US tablespoon (US tbsp) → cubic inch (in³)

1 US tbsp equals 0.90234375 in³. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US tablespoon and cubic inch 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 tbsp = 0.90234375 in³ · 10 US tbsp = 9.0234375 in³.

0.90234375 in³
