Convert Kilograms per square metre per hour to Grams per square centimetre per second
Convert Kilograms per square metre per hour (kg/(m²·h)) to Grams per square centimetre per second (g/(cm²·s)) instantly and accurately.
Conversion Formula
g/(cm²·s) = kg/(m²·h) × 2.777777778e-5
About Kilograms per square metre per hour
The kilogram per square metre per hour (kg/(m²·h)) equals 1/3600 ≈ 2.778 × 10⁻⁴ kg/(m²·s). It is the most common practical SI-based unit in process engineering for mass transfer coefficients, boiler evaporation rates, and precipitation flux in meteorology. Rain of 10 mm/h ≈ 10 kg/(m²·h). 1 kg/(m²·h) = 1 000 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).
