Convert Cubic inches per hour to Kilolitres per second
Convert Cubic inches per hour (in³/h) to Kilolitres per second (kL/s) instantly and accurately.
Conversion Formula
kL/s = in³/h × 4.551962222e-9
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.
About Kilolitres per second
The kilolitre per second (kL/s) equals 1 m³/s, so 1 kL/s is identical to 1 m³/s. The term kilolitre is favoured in Australian and South African engineering over the equivalent cubic metre per second. Municipal water-main flow and stormwater-channel capacity are sometimes expressed in kL/s in these countries. 1 kL/s = 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min.
