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

Conversion Formula

mm²/min = in²/h × 10.75266667

About Square inches per hour

The square inch per hour (in²/h) equals 0.0254²/3600 ≈ 1.792 × 10⁻⁷ m²/s. It is found in US heat-transfer and diffusion textbooks that use the BTU-inch-hour unit system alongside thermal diffusivity tables. 1 in²/h ≈ 0.1792 cSt.

About Square millimetres per minute

The square millimetre per minute (mm²/min) equals 1/(6 × 10⁷) m²/s ≈ 1.667 × 10⁻⁸ m²/s. It is used in polymer-film formation and printing-ink diffusion studies where minute-scale time resolution is more convenient. 1 mm²/min = 1/60 cSt.
