Convert Cubic feet per hour to Acre-feet per day
Convert Cubic feet per hour (ft³/h) to Acre-feet per day (ac-ft/d) instantly and accurately.
Conversion Formula
ac-ft/d = ft³/h × 0.0005509641873
About Cubic feet per hour
The cubic foot per hour (ft³/h) equals 0.028316846592/3600 ≈ 7.866×10⁻⁶ m³/s, used in US natural-gas metering (residential gas meters read in cubic feet; billing converts to CCF = 100 ft³) and historical furnace-fuel-consumption tables. A US residential gas furnace consumes 80-200 ft³/h of natural gas at full fire. 1 ft³/h ≈ 7.866×10⁻⁶ m³/s.
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.
