Convert Milligrams per square metre per hour to Grams per square centimetre per second
Convert Milligrams per square metre per hour (mg/(m²·h)) to Grams per square centimetre per second (g/(cm²·s)) instantly and accurately.
Conversion Formula
g/(cm²·s) = mg/(m²·h) × 2.777777778e-11
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 Grams per square centimetre per second
The gram per square centimetre per second (g/(cm²·s)) equals 10 kg/(m²·s) (exact: 1 g = 10⁻³ kg; 1 cm² = 10⁻⁴ m²). It is the CGS coherent mass flux unit and appears in older combustion engineering, rocket propulsion, and nuclear reactor thermal-hydraulic literature. Solid-rocket burn rates: 0.01-0.2 g/(cm²·s). 1 g/(cm²·s) = 10 kg/(m²·s).
