About Litres per second

The litre per second (L/s) equals 10⁻³ m³/s, the standard unit for municipal water-supply engineering, fire-fighting flows, and HVAC system air handling. A fire hydrant delivers 15-30 L/s; a household mains water connection is typically 0.1-0.5 L/s; a large building HVAC chilled-water loop circulates 50-200 L/s. 1 L/s = 10⁻³ m³/s = 3.6 m³/h ≈ 15.85 US gal/min.

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.
