1 " micron" = 1 xx 10^-6 m

Explanation:

Dividing 1 mm by 1000 gives micrometres, also called microns.

For measurements that are very small we need a scale smaller even than mm.

The thickness of layers such as paint, plastic linings, pages, even a human hair can be measured in microns.

1m div 1000 rarr 1mm = 1 xx 10^-3m

1mm div 1000 = micron = 1 xx 10^-3 xx 10^-3 m

Therefore 1m div 1000 div 1000 = 1 " micron" = 1 xx 10^-6 m
