About UK gallons per minute
The UK (imperial) gallon per minute (gpm) equals 4.54609×10⁻³/60 ≈ 7.577×10⁻⁵ m³/s, historically used in British plumbing design, pump curves, and water-treatment plant sizing. Pre-metric UK water-industry capacity tables and pump manufacturers quoted flows in UK gal/min; legacy British Standard BS EN pump curves often show both units. 1 UK gpm ≈ 7.577×10⁻⁵ m³/s ≈ 4.546 L/min.
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.
