Convert Square inches per hour to Square metres per minute
Convert Square inches per hour (in²/h) to Square metres per minute (m²/min) instantly and accurately.
Conversion Formula
m²/min = in²/h × 1.075266667e-5
About Square inches per hour
The square inch per hour (in²/h) equals ≈1.792 × 10⁻⁷ m²/s, used in US heat-transfer handbooks and HVAC insulation specifications. Pre-SI tables for building insulation board and refractory brick often list thermal diffusivity in in²/h. Firebrick: ≈3.5 in²/h; rigid foam: ≈0.8-1.2 in²/h. 1 in²/h = 0.00064516/3600 m²/s.
About Square metres per minute
The square metre per minute (m²/min) equals 1/60 m²/s ≈0.01667 m²/s, a non-standard unit seen in some process-engineering contexts where heat soak times are measured in minutes rather than seconds. Nuclear fuel rod thermal analysis and large refractory furnace lining design occasionally cite diffusivity in m²/min. 1 m²/min = 1/60 m²/s ≈ 6000 cm²/s.
