Conversion Formula
lb/(in²·s) = mg/(m²·h) × 3.950928696e-13
About Milligrams per square metre per hour
The milligram per square metre per hour (mg/(m²·h)) equals 10⁻⁶/3600 ≈ 2.778 × 10⁻¹⁰ kg/(m²·s). It is the standard unit in corrosion science and protective-coating industry for measuring corrosion rate or moisture vapour transmission rate (MVTR) of membranes and packaging films. Rates of 1-100 mg/(m²·h) are typical for polymer films. 1 mg/(m²·h) = 10⁻³ g/(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).
