Convert Grams per square metre per hour to Pounds per square inch per second
Convert Grams per square metre per hour (g/(m²·h)) to Pounds per square inch per second (lb/(in²·s)) instantly and accurately.
Conversion Formula
lb/(in²·s) = g/(m²·h) × 3.950928696e-10
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 inch per second
The pound per square inch per second (lb/(in²·s)) equals 0.45359237/(0.0254 × 0.0254) ≈ 703.07 kg/(m²·s). It is used in US firearms ballistics, shaped-charge and explosives engineering, and hydraulic press analysis where forces per square inch dominate the unit system. 1 lb/(in²·s) ≈ 703.07 kg/(m²·s) = 144 lb/(ft²·s).
