How to convert nanometers to millimeters
1 nanometer = 0.000001 millimeters. To convert nanometers to millimeters, divide by 1,000,000 (or multiply by 0.000001). A nanometer is one billionth of a meter (10⁻⁹ m). A millimeter is one thousandth of a meter.
Worked examples
- 500 nanometers = 0.0005 mm (500 ÷ 1,000,000)
- 1,000 nanometers = 0.001 mm (1,000 ÷ 1,000,000)
- 100,000 nanometers = 0.1 mm (100,000 ÷ 1,000,000)
Where this conversion comes up
Nanometers are used for light wavelengths, chip features and molecules; millimeters for screw and drill sizes, rainfall, paper and phone dimensions. Wavelengths and chip features are quoted in nanometers while machining and optics drawings use millimeters. One nanometer is exactly 10⁻⁶ mm, so green light at 550 nm is 0.00055 mm, and 1,000,000 nm is exactly 1 mm. Here nm means nanometer; for torque, nm usually means newton meter.
Quick estimate
Divide by 1,000,000, or move the decimal point six places to the left.
Common mistakes
- Multiplying instead of dividing. A millimeter is larger than a nanometer, so the number of millimeters must come out smaller: 500 nanometers = 0.0005 mm.
