How to convert
To convert nm to µm, multiply: µm = nm × 0.001
To convert µm to nm, divide: nm = µm ÷ 0.001 (equivalently × 1,000).
Example: 1,000 nm × 0.001 = 1 µm. The factor is derived from the international definition of each unit; results are shown to 4 significant figures.
Frequently asked questions
1,000 nm = 1 µm. The formula is: value in nm × 0.001 = value in µm. Use the converter above to convert any value instantly.
1 µm = 1,000 nm. To convert back, divide the µm value by 0.001 (or multiply by 1,000).
µm = nm × 0.001; conversely nm = µm ÷ 0.001. For example, 1,000 nm × 0.001 = 1 µm. The factor comes from the international definition of the units.
