Convert Pounds per square foot per hour to Grams per square centimetre per second
Convert Pounds per square foot per hour (lb/(ft²·h)) to Grams per square centimetre per second (g/(cm²·s)) instantly and accurately.
Conversion Formula
g/(cm²·s) = lb/(ft²·h) × 0.0001356229899
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 centimetre per second
The gram per square centimetre per second (g/(cm²·s)) equals 10 kg/(m²·s) (exact: 1 g = 10⁻³ kg; 1 cm² = 10⁻⁴ m²). It is the CGS coherent mass flux unit and appears in older combustion engineering, rocket propulsion, and nuclear reactor thermal-hydraulic literature. Solid-rocket burn rates: 0.01-0.2 g/(cm²·s). 1 g/(cm²·s) = 10 kg/(m²·s).
