Convert Kilograms per square metre per hour to Pounds per square foot per second
Convert Kilograms per square metre per hour (kg/(m²·h)) to Pounds per square foot per second (lb/(ft²·s)) instantly and accurately.
Conversion Formula
lb/(ft²·s) = kg/(m²·h) × 5.689337323e-5
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 foot per second
The pound per square foot per second (lb/(ft²·s)) equals 0.45359237/0.09290304 ≈ 4.882 kg/(m²·s). It is the coherent FPS mass flux unit, used in US aerospace for rocket motor mass flux, ballistic studies, and hypervelocity heat-shield ablation rate specifications. 1 lb/(ft²·s) ≈ 4.882 kg/(m²·s).
