μm/yr
micrometer per year
Corrosion rateexact by definition
The micrometre per year is exactly 1e-6 m/yr by decimal prefix, and it is the unit for the very low rates found on passivated stainless steel, on well-inhibited closed loops, and in atmospheric corrosion studies. It is also convenient because 25.4 μm/yr is exactly 1 mil per year, making the mental conversion straightforward.
