Convert Kilograms per square metre per hour to Pounds per square inch per second
Convert Kilograms per square metre per hour (kg/(m²·h)) to Pounds per square inch per second (lb/(in²·s)) instantly and accurately.
Conversion Formula
lb/(in²·s) = kg/(m²·h) × 3.950928696e-7
About Kilograms per square metre per hour
The kilogram per square metre per hour (kg/(m²·h)) equals 1/3600 ≈ 2.778 × 10⁻⁴ kg/(m²·s). It is the most common practical SI-based unit in process engineering for mass transfer coefficients, boiler evaporation rates, and precipitation flux in meteorology. Rain of 10 mm/h ≈ 10 kg/(m²·h). 1 kg/(m²·h) = 1 000 g/(m²·h).
About Pounds per square inch per second
The pound per square inch per second (lb/(in²·s)) equals 0.45359237/(0.0254 × 0.0254) ≈ 703.07 kg/(m²·s). It is used in US firearms ballistics, shaped-charge and explosives engineering, and hydraulic press analysis where forces per square inch dominate the unit system. 1 lb/(in²·s) ≈ 703.07 kg/(m²·s) = 144 lb/(ft²·s).
