The conversion factor between micro-inches (µ") and micro-meters (µm) is multiplying by 0.025 which is equivalent to dividing by 40. In the conversion requested, 32 micro-inches are therefore equal to 0.8 micro-meters. A. 1 meter = 39.37 inch.

It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is typically considered to be the high-frequency, short …
