Formula
Formula
m = μm × 1e-6
Multiply any value in micrometres by 1e-6 to obtain the value in metres.
Worked example
Convert 1.00000e+6 μm to m.
- 01Start with 1.00000e+6 μm.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 m.
Result1.00000e+6 μm = 1 m

FAQ
What is the conversion factor from μm to m?
1 μm equals 1e-6 m. To convert, multiply the value in micrometres by 1e-6.
How do I convert 1 μm to m?
1 μm = 1e-6 m. For any value, multiply by 1e-6.
How do I convert m back to μm?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 m = 1.00000e+6 μm.
When would I need to convert micrometre 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 μm and m are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
