Nanometer to micrometer to millimeter, length unit conversion

A nanometer is a unit of length.

1 nanometer = 1 billionth of a meter (10⁻⁹ meter), approximately the size of a molecule or DNA. Viruses have a diameter of approximately 60 to 250 nanometers.

The diameter of a red blood cell is approximately 2,000 nanometers .

The diameter of a hair is approximately 30,000 to 50,000 nanometers, or 30 to 50 micrometers.

Dust mites are approximately 100 to 400 micrometers in size, with adults being about 300 micrometers.

Mini LED (sub-millimeter light-emitting diode) is an LED with a chip size of approximately 100 micrometers.

Micro LED (microlight-emitting diode) refers to LEDs with a chip size of less than 50 micrometers.

1 meter (m) = 1 square meter; 1 millimeter (mm) = 10 to the power of negative 3 m = 0.001 m = 1 mm; 1 micrometer (μm) = 10 to the power of negative 6 m = 0.001 mm = 0.001 mm; 1 nanometer (nm) = 10 to the power of negative 9 m = 0.001 μm = 0.000001 mm
