Convert Square inches per second to Square millimetres per hour
Convert Square inches per second (in²/s) to Square millimetres per hour (mm²/h) instantly and accurately.
Conversion Formula
mm²/h = in²/s × 2322576
About Square inches per second
The square inch per second (in²/s) equals 0.0254² = 6.4516 × 10⁻⁴ m²/s. It is the coherent FPS kinematic unit based on the inch, found in US fluid power, hydraulics, and bearing-design references. 1 in²/s = 645.16 cSt = 6.4516 St.
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.
