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

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