Convert Pounds per square foot per hour to Grams per square metre per second
Convert Pounds per square foot per hour (lb/(ft²·h)) to Grams per square metre per second (g/(m²·s)) instantly and accurately.
Conversion Formula
g/(m²·s) = lb/(ft²·h) × 1.356229899
About Pounds per square foot per hour
The pound per square foot per hour (lb/(ft²·h)) equals 0.45359237/(0.09290304 × 3600) ≈ 1.356 × 10⁻³ kg/(m²·s). It is used in US heat and mass transfer texts (e.g., Perry's Chemical Engineers' Handbook) for mass flux through surfaces in drying, absorption, and distillation operations using consistent BTU-lb-h units. 1 lb/(ft²·h) ≈ 1.356 g/(m²·s).
About Grams per square metre per second
The gram per square metre per second (g/(m²·s)) equals 10⁻³ kg/(m²·s). It is used in combustion engineering for solid-propellant burn rate and ablation rate data, and in food-process engineering for spray drying and freeze-drying mass-transfer calculations. 1 g/(m²·s) = 3 600 g/(m²·h).
