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 UK gallons per second
The UK (imperial) gallon per second (gal/s) equals 4.54609×10⁻³ m³/s, about 20% larger than the US gallon per second. It appears in pre-metric British fire-fighting standards, large pump test certificates, and naval engineering calculations. A UK fire engine pump rated 1 000 UK gal/min delivers ≈16.67 UK gal/s. 1 UK gal/s = 4.54609×10⁻³ m³/s ≈ 1.201 US gal/s.
