nm stands for nanometres, it is not a measure of speed, but length
68 nm is equivalent to 0.000000068 meters.
My guess is that the NM stands for National Match, a better quality barrel
The wave length of visible light ranges from 400 nm to 700 nm
As of January 1, 2009, the Albuquerque minimum wage is $7.50 per hour.
The wavelength of ultraviolet radiation ranges from about 10 nm to 400 nm. Within this range, different types of UV radiation have varying wavelengths: UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm).
"nm" stands for nanometers, a measure of length.
It is 0.000000068 metres.

nm is nano-meters. There will be a number preceding the nm. This number indicates how many nano-meters for a full wave length of the laser light.
