Square inches per minute (in²/min)
Square millimetres per hour (mm²/h)

Conversion Formula

mm²/h = in²/min × 38709.6

About Square inches per minute

The square inch per minute (in²/min) equals 0.0254²/60 ≈ 1.075 × 10⁻⁵ m²/s. It appears in US coating and printing industry references where area coverage rates in in²/min are combined with kinematic flow data. 1 in²/min ≈ 10.75 cSt.

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.
