Conversion Formula

in³/h = gal/s × 831600

About US gallons per second

The US gallon per second (gal/s) equals 3.785411784×10⁻³ m³/s, used for very large pump discharge rates and fire-suppression deluge systems. A large centrifugal fire pump rated 1 500 US gal/min delivers exactly 25 US gal/s; industrial cooling-tower makeup lines are sized in gal/s at peak demand. 1 US gal/s = 3.785411784×10⁻³ m³/s = 60 US gal/min ≈ 227.1 L/min.

About Cubic inches per hour

The cubic inch per hour (in³/h) equals 1.6387064×10⁻⁵/3600 ≈ 4.552×10⁻⁹ m³/s, appearing in US oilfield plunger-pump capacity datasheets and slow hydraulic-actuator specifications. It is also used in US ASTM leak-test standards where maximum allowable leakage past a valve seal is expressed in in³/h at rated pressure. 1 in³/h ≈ 4.552×10⁻⁹ m³/s.
