Formula
Formula
m = nm × 1e-9
Multiply any value in nanometres by 1e-9 to obtain the value in metres.
Worked example
Convert 1e+9 nm to m.
- 01Start with 1e+9 nm.
- 02Multiply by the conversion factor: 1e+9 × 1e-9 = 1 m.
Result1e+9 nm = 1 m

FAQ
What is the conversion factor from nm to m?
1 nm equals 1e-9 m. To convert, multiply the value in nanometres by 1e-9.
How do I convert 1 nm to m?
1 nm = 1e-9 m. For any value, multiply by 1e-9.
How do I convert m back to nm?
Divide by the same factor — or equivalently, multiply by 1e+9. So 1 m = 1e+9 nm.
When would I need to convert nanometre to metre?
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 m are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
