Convert Square millimetres per hour to Square centimetres per second
Convert Square millimetres per hour (mm²/h) to Square centimetres per second (cm²/s) instantly and accurately.
Conversion Formula
cm²/s = mm²/h × 2.777777778e-6
About Square millimetres per hour
The square millimetre per hour (mm²/h) equals 1/(3.6 × 10⁹) m²/s ≈ 2.78 × 10⁻¹⁰ m²/s. It appears in materials science for solid-state diffusion and thin-film growth studies where hourly timescales are more natural than seconds. 1 mm²/h = 1/3600 mm²/s = 1/3600 cSt.
About Square centimetres per second
The square centimetre per second (cm²/s) equals 10⁻⁴ m²/s, numerically identical to 1 stoke (St). It is the explicit CGS dimensional form, preferred in dimensional analysis or when avoiding named units. 1 cm²/s = 1 St = 100 cSt.
