Convert Square inches per hour to Square metres per hour
Convert Square inches per hour (in²/h) to Square metres per hour (m²/h) instantly and accurately.
Conversion Formula
m²/h = in²/h × 0.00064516
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 metres per hour
The square metre per hour (m²/h) equals 1/3600 m²/s ≈ 277.8 cSt. It is convenient in European process engineering when kinematic viscosity is used alongside metre-based pipe geometry and hourly flow rates. 1 m²/h ≈ 277.8 cSt.
