Convert Grams per square metre per hour to Grams per square metre per second
Convert Grams per square metre per hour (g/(m²·h)) to Grams per square metre per second (g/(m²·s)) instantly and accurately.
Conversion Formula
g/(m²·s) = g/(m²·h) × 0.0002777777778
About Grams per square metre per hour
The gram per square metre per hour (g/(m²·h)) equals 10⁻³/3600 ≈ 2.778 × 10⁻⁷ kg/(m²·s). It is widely used in textile and paper engineering for moisture management, evaporation studies, and water-vapour transmission rate (WVTR) testing of barrier materials per ISO 2528 and ASTM E96. Breathable fabrics range 500-10 000 g/(m²·h) (=500-10 000 gsm/h). 1 g/(m²·h) = 10⁻³ kg/(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).
