Convert Cubic inches per hour to Acre-feet per hour
Convert Cubic inches per hour (in³/h) to Acre-feet per hour (ac-ft/h) instantly and accurately.
Conversion Formula
ac-ft/h = in³/h × 1.328520899e-8
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 hour
The acre-foot per hour (ac-ft/h) equals 1233.48183754752/3600 ≈ 0.34263 m³/s, standard for sizing irrigation district delivery canals, reservoir outflow scheduling, and aquifer recharge basin calculations in the western US. The US Bureau of Reclamation uses ac-ft/h for canal operational planning; a 1 000-acre farm irrigating with 0.5 in/h rain-equivalent receives ≈41 ac-ft/h. 1 ac-ft/h ≈ 0.34263 m³/s.
