How to convert meters to nanometers
1 meter = 1,000,000,000 nanometers. To convert meters to nanometers, multiply by 1,000,000,000. The meter is the SI base unit of length, defined by the speed of light. A nanometer is one billionth of a meter (10⁻⁹ m).
Worked examples
- 1e-9 meters = 1 nm (1e-9 × 1,000,000,000)
- 5.5e-7 meters = 550 nm (5.5e-7 × 1,000,000,000)
- 1 meter = 1,000,000,000 nm (1 × 1,000,000,000)
Where this conversion comes up
Meters are used for room sizes, building heights and running distances; nanometers for light wavelengths, chip features and molecules. Nanometers describe light wavelengths and chip features, meters are the SI base unit used in physics formulas such as the speed of light. A nanometer is 10⁻⁹ m, so one meter is 1,000,000,000 nm and green light at 5.5×10⁻⁷ m is 550 nm. Not to be confused with nm as an abbreviation for nautical miles or newton-meters.
Quick estimate
Move the decimal point nine places to the right: 0.000001 m = 1,000 nm.
Common mistakes
- Dividing instead of multiplying. A nanometer is smaller than a meter, so the number of nanometers must come out larger: 1e-9 meters = 1 nm.
