How to convert nanometers to centimeters
1 nanometer = 1e-7 centimeters. To convert nanometers to centimeters, divide by 10,000,000 (or multiply by 1e-7). A nanometer is one billionth of a meter (10⁻⁹ m). A centimeter is one hundredth of a meter.
Worked examples
- 1 nanometer = 1e-7 cm (1 ÷ 10,000,000)
- 500 nanometers = 0.00005 cm (500 ÷ 10,000,000)
- 10,000,000 nanometers = 1 cm (10,000,000 ÷ 10,000,000)
Where this conversion comes up
Nanometers are used for light wavelengths, chip features and molecules; centimeters for body height, clothing and furniture sizes. Spectroscopy formulas often need wavelength in centimeters (wavenumbers are given in cm⁻¹), while light sources are labeled in nanometers. One centimeter is 10,000,000 nm, so 500 nm green light is 5 × 10⁻⁵ cm and its wavenumber is 20,000 cm⁻¹. Here nm means nanometers, not newton-meters or nautical miles.
Quick estimate
Move the decimal point seven places left: 650 nm = 0.000065 cm.
Common mistakes
- Multiplying instead of dividing. A centimeter is larger than a nanometer, so the number of centimeters must come out smaller: 1 nanometer = 1e-7 cm.
