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 Fathom
The fathom equals 6 feet (1.8288 m) and is the traditional unit for water depth on nautical charts.
Fun Fact: The word comes from the Old English "fæðm", the span of a man's outstretched arms.
Common uses: sounding depth, nautical charts, diving.
