Converter
nm
Accepts numbers or expressions, e.g. 150 + 14.7
Result
μm
Rendered to 6 significant figures.
Formula
Formula
μm = nm × 0.001
Multiply any value in nanometres by 0.001 to obtain the value in micrometres.
Worked example
Convert 1000 nm to μm.
- 01Start with 1000 nm.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 μm.
Result1000 nm = 1 μm

FAQ
What is the conversion factor from nm to μm?
1 nm equals 0.001 μm. To convert, multiply the value in nanometres by 0.001.
How do I convert 1 nm to μm?
1 nm = 0.001 μm. For any value, multiply by 0.001.
How do I convert μm back to nm?
Divide by the same factor — or equivalently, multiply by 1000. So 1 μm = 1000 nm.
When would I need to convert nanometre to micrometre?
Length conversions appear in piping, layout, and mechanical drawings — particularly when reconciling imperial fittings or instrument lengths with metric plant drawings.
Is the conversion exact?
Yes. Both nm and μm are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
