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).
About Milligrams per square metre per minute
The milligram per square metre per minute (mg/(m²·min)) equals 10⁻⁶/60 ≈ 1.667 × 10⁻⁸ kg/(m²·s). It appears in pharmaceutical dissolution testing and transdermal drug-delivery patch characterisation, where drug release rates measured minute-by-minute are compared to in-vivo absorption data. 1 mg/(m²·min) = 60 mg/(m²·h).
