A nanometer (nm) is one billionth (10⁻⁹) of a meter, which is the base unit of length in the International System of Units (SI). Nanometers are commonly used in nanotechnology, semiconductor manufacturing, and scientific research to measure extremely small distances.
| Nanometers (nm) | Meters (m) |
|---|---|
| 1 nm | 1 × 10⁻⁹ m |
| 1,000 nm | 1 × 10⁻⁶ m (1 micrometer) |
| 1,000,000 nm | 1 × 10⁻³ m (1 millimeter) |
| 1,000,000,000 nm | 1 m |
To convert nanometers to meters, divide the number of nanometers by 1,000,000,000 (or multiply by 10⁻⁹).
Convert 500 nanometers to meters:
500 nm = 500 ÷ 1,000,000,000 = 5 × 10⁻⁷ meters
Nanometer measurements are commonly used in:
