Microns and microinches conversion factors

Our tube mill manufactures products specified down as far as micron level, in some cases. That’s just a millionth of a metre. The following conversion tables outline the units used to measure tubes in our range including metric and imperial units.

Conversion factors

1 mm = 0.001 m
1 micron (µm) = 0.000001 m
1 mm = 1000 micron (µm)
0.1 mm = 100 micron (µm)
   
1 inch = 25.4 mm
1 micro inch (µ”) = 0.000001 x 25.4 x 1000 µm (micron)
  = 0.0254 µm (micron)
32 µ” = 0.81 µm
   
1 milli =  1 thousandth
1 micro =  1 millionth
1 mm =  1 thousandth of a metre
1 micron =  1 millionth of a metre
