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.
About Acre-feet per second
The acre-foot per second (ac-ft/s) equals 1233.48183754752 m³/s, an enormous unit representing the flow that would fill a football-field-sized area to 1 ft depth every second. It appears in descriptions of exceptionally large dam-break flood waves and major river-system extreme events. The 1976 Teton Dam collapse peak outflow was estimated at ≈65 000 ft³/s ≈ 1.49 ac-ft/s. 1 ac-ft/s = 1 233.48 m³/s.
