Convert Cubic inches per hour to Cubic metres per second
Convert Cubic inches per hour (in³/h) to Cubic metres per second (m³/s) instantly and accurately.
Conversion Formula
m³/s = in³/h × 4.551962222e-9
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.
About Cubic metres per second
The cubic metre per second (m³/s) is the SI coherent unit of volumetric flow rate. It is used for large river discharges, turbine inlet flows, and major pipeline capacities. The Amazon River at its mouth averages ≈200 000 m³/s; a large hydroelectric turbine passes 400-800 m³/s; a major municipal water-main carries 5-20 m³/s. 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min = 35.315 ft³/s.
