square inch per second
Diffusivityexact by definition
The square inch per second is exactly 6.4516 × 10⁻⁴ m²/s. It appears in American thermal analysis, where thermal diffusivity is occasionally tabulated in inch units to match a geometry given in inches, and in some hydraulic fluid specifications.
