Convert Acre-feet per day to Cubic inches per hour
Convert Acre-feet per day (ac-ft/d) to Cubic inches per hour (in³/h) instantly and accurately.
Conversion Formula
in³/h = ac-ft/d × 3136320
About Acre-feet per day
The acre-foot per day (ac-ft/d) equals 1233.48183754752/86400 ≈ 0.014278 m³/s, the practical unit for daily water-delivery scheduling in western US irrigation districts and river-compact administration. Water rights in the Colorado River system are specified in acre-feet per year; daily delivery schedules convert to ac-ft/d. A moderate-size irrigation lateral delivers 5-50 ac-ft/d. 1 ac-ft/d ≈ 0.014278 m³/s ≈ 504.2 US gal/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.
