Micrometer (µm)
Length
Traceable to the metre, defined by fixing the speed of light in vacuum at 299 792 458 m/s. Imperial lengths derive from the 1959 international yard (0.9144 m exactly).

About Micrometer
The micrometre (micron) equals one millionth of a metre. It is the working scale of cells, machining tolerances and airborne particulates.
Common uses: microscopy, machining tolerances, air quality (PM).
About Chain
Gunter's chain equals 66 feet (20.1168 m) and underpins the US Public Land Survey System: 10 square chains make one acre.
Common uses: land surveying, cadastral records, cricket pitch length.
