Formula
nm to μm conversion formula
Use this relationship for a direct conversion:
μm = nm x 0.001
Worked example
2 nm = 0.002 μm.
Vacuum propagation is assumed. A medium-specific velocity factor must be applied for practical cables and materials.

nm to μm FAQ
How do you convert wavelength in nanometers to wavelength in micrometers?
Use the formula μm = nm x 0.001. 1 wavelength in nanometers (nm) equals 0.001 wavelength in micrometers (μm).
Is the nm to μm conversion exact?
Vacuum propagation is assumed. A medium-specific velocity factor must be applied for practical cables and materials.
