Convert Milligrams per square metre per hour to Grams per square metre per second

Convert Milligrams per square metre per hour (mg/(m²·h)) to Grams per square metre per second (g/(m²·s)) instantly and accurately.

Milligrams per square metre per hour (mg/(m²·h))
Grams per square metre per second (g/(m²·s))

Conversion Formula

g/(m²·s) = mg/(m²·h) × 2.777777778e-7

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 metre per second

The gram per square metre per second (g/(m²·s)) equals 10⁻³ kg/(m²·s). It is used in combustion engineering for solid-propellant burn rate and ablation rate data, and in food-process engineering for spray drying and freeze-drying mass-transfer calculations. 1 g/(m²·s) = 3 600 g/(m²·h).
