About US fluid ounces per hour

The US fluid ounce per hour (fl oz/h) equals 3.785411784×10⁻³/128/3600 ≈ 8.215×10⁻⁹ m³/s, used in low-flow medical devices and slow-infusion clinical equipment. A nasal cannula oxygen humidifier delivers humidity at 10-50 fl oz/h of water vapour equivalent; micro-dosing chemical feed pumps for water treatment are calibrated in fl oz/h in US systems. 1 fl oz/h ≈ 8.215×10⁻⁹ m³/s.

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.
