Convert Square inches per hour to Stokes
Convert Square inches per hour (in²/h) to Stokes (St) instantly and accurately.
Conversion Formula
St = in²/h × 0.001792111111
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 Stokes
The stoke (St) equals 1 cm²/s = 10⁻⁴ m²/s, the CGS unit of kinematic viscosity named after Sir George Gabriel Stokes. Its hundredth part, the centistoke, is now dominant, but the stoke still appears in older fluid-mechanics texts and archival API and ASTM data. Water at 20 °C ≈ 0.01004 St; air at 20 °C ≈ 0.1516 St. 1 St = 100 cSt = 10⁻⁴ m²/s.
