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 Cubic inches per hour
The cubic inch per hour (in³/h) equals 1.6387064×10⁻⁵/3600 ≈ 4.552×10⁻⁹ m³/s, appearing in US oilfield plunger-pump capacity datasheets and slow hydraulic-actuator specifications. It is also used in US ASTM leak-test standards where maximum allowable leakage past a valve seal is expressed in in³/h at rated pressure. 1 in³/h ≈ 4.552×10⁻⁹ m³/s.
