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 foot per minute
The pound per square foot per minute (lb/(ft²·min)) equals 0.45359237/(0.09290304 × 60) ≈ 0.08137 kg/(m²·s). It appears in US filtration and membrane technology standards, where filter-press and belt-press dewatering rates are stated per square foot per minute. 1 lb/(ft²·min) ≈ 81.37 g/(m²·s).
