Convert Cubic inches per hour to Acre-feet per minute
Convert Cubic inches per hour (in³/h) to Acre-feet per minute (ac-ft/min) instantly and accurately.
Conversion Formula
ac-ft/min = in³/h × 2.214201499e-10
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 Acre-feet per minute
The acre-foot per minute (ac-ft/min) equals 1233.48183754752/60 ≈ 20.558 m³/s, encountered in large irrigation canal capacity descriptions and reservoir emergency spillway sizing in the US West. A major canal gate releasing 1 ac-ft/min drains a 1-acre field 1 foot deep every minute - a substantial agricultural flow. 1 ac-ft/min ≈ 20.558 m³/s ≈ 726.0 ft³/s.
