Convert Grams per square metre per hour to Pounds per square foot per second
Convert Grams per square metre per hour (g/(m²·h)) to Pounds per square foot per second (lb/(ft²·s)) instantly and accurately.
Conversion Formula
lb/(ft²·s) = g/(m²·h) × 5.689337323e-8
About Grams per square metre per hour
The gram per square metre per hour (g/(m²·h)) equals 10⁻³/3600 ≈ 2.778 × 10⁻⁷ kg/(m²·s). It is widely used in textile and paper engineering for moisture management, evaporation studies, and water-vapour transmission rate (WVTR) testing of barrier materials per ISO 2528 and ASTM E96. Breathable fabrics range 500-10 000 g/(m²·h) (=500-10 000 gsm/h). 1 g/(m²·h) = 10⁻³ kg/(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).
