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 Kilograms per square centimetre per second

The kilogram per square centimetre per second (kg/(cm²·s)) equals 10⁴ kg/(m²·s) (exact: 1 cm² = 10⁻⁴ m²). It is used for extreme high-pressure mass-flux situations such as detonation physics, shaped-charge jet penetration, and hypervelocity impact analysis. 1 kg/(cm²·s) = 10⁴ kg/(m²·s) = 1 000 g/(cm²·s).
