What this calculator does
Converts a measurement given in metres into nanometres using the defined conversion factor.
What your result means
The same quantity expressed in nm instead of m. Nothing about the measurement itself changes.
Formula and working
nm = m × 1,000,000,000
- 1
Start with your value
1 m
- 2
Convert to meter
1 × 1 = 1 m
- 3
Convert into nanometers
1 ÷ 1.0000e-9 = 1,000,000,000 nm
- 4
Result
1 m = 1,000,000,000 nm
Frequently asked questions
Symbols and assumptions
- m
- Input unit — metre
- nm
- Output unit — nanometre
- • Both units measure length and distance, so the physical quantity is unchanged by the conversion.
- • The relationship is exactly linear: 1 m = 1,000,000,000 nm.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.
