Conversion Formula
ac-ft/h = m³/s × 2.918567498
About Cubic metres per second
The cubic metre per second (m³/s) is the SI coherent unit of volumetric flow rate. It is used for large river discharges, turbine inlet flows, and major pipeline capacities. The Amazon River at its mouth averages ≈200 000 m³/s; a large hydroelectric turbine passes 400-800 m³/s; a major municipal water-main carries 5-20 m³/s. 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min = 35.315 ft³/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.
