About Cubic feet per day
The cubic foot per day (ft³/d) equals 0.028316846592/86400 ≈ 3.277×10⁻⁷ m³/s, found in US oil-and-gas production reports for low-rate gas wells and groundwater monitoring wells. A marginal coalbed-methane well producing 50 Mcf/d (50 000 ft³/d) of gas represents a modest but economic flow; residential water-well yield tests report in ft³/d. 1 ft³/d ≈ 3.277×10⁻⁷ m³/s.
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.
