Convert Cubic inches per hour to Cubic feet per second
Convert Cubic inches per hour (in³/h) to Cubic feet per second (ft³/s) instantly and accurately.
Conversion Formula
ft³/s = in³/h × 1.607510288e-7
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 feet per second
The cubic foot per second (ft³/s or cfs) equals 0.028316846592 m³/s, the primary unit for measuring river discharge and open-channel flow in the United States. The US Geological Survey publishes all streamflow data in cfs; irrigation water rights, flood-control gates, and dam spillway capacities are specified in cfs. The Colorado River at full natural flow is ≈22 000 cfs. 1 cfs = 0.028316846592 m³/s ≈ 28.317 L/s ≈ 448.8 US gpm.
