Formula
μm to nm conversion formula
Use this relationship for a direct conversion:
nm = μm x 1,000
Worked example
2 μm = 2,000 nm.
Vacuum propagation is assumed. A medium-specific velocity factor must be applied for practical cables and materials.

μm to nm FAQ
How do you convert wavelength in micrometers to wavelength in nanometers?
Use the formula nm = μm x 1,000. 1 wavelength in micrometers (μm) equals 1,000 wavelength in nanometers (nm).
Is the μm to nm conversion exact?
Vacuum propagation is assumed. A medium-specific velocity factor must be applied for practical cables and materials.
