Convert Grams per square metre per hour to Grams per square centimetre per second
Convert Grams per square metre per hour (g/(m²·h)) to Grams per square centimetre per second (g/(cm²·s)) instantly and accurately.
Conversion Formula
g/(cm²·s) = g/(m²·h) × 2.777777778e-8
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 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).
