Millimetres to Nanometres Converter
Convert millimetres (mm) to nanometres (nm) instantly. Length conversions come up when reading overseas furniture specs, cycling the Round Island Route in kilometres while a foreign app shows miles, or checking marine distances in the Singapore Strait in nautical miles.
Result
- Nanometres
- 1,000,000 nm
How to use the millimetres to nanometres converter
- Enter the millimetres (mm).
- The results update as you type, or press Calculate.
- Read the nanometres first, then the supporting figures below it.
Formula
Nanometres = millimetres × 1,000,000
Worked example
For example, with these inputs:
- Millimetres (mm): 1
the calculator returns:
- Nanometres: 1,000,000 nm

About this conversion
Length conversions come up when reading overseas furniture specs, cycling the Round Island Route in kilometres while a foreign app shows miles, or checking marine distances in the Singapore Strait in nautical miles.
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.
