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 US quarts per second
The US quart per second (qt/s) equals 3.785411784×10⁻³/4 ≈ 9.464×10⁻⁴ m³/s, used in US industrial filling lines handling quart-size containers (motor oil, paint, sauce). A high-speed filling machine loading 1 qt bottles at 4 per second processes 4 qt/s per nozzle. 1 US qt/s ≈ 9.464×10⁻⁴ m³/s = 0.9464 L/s.
