    How many Nanometers in a Micrometer?

Nanometers and micrometers are metric units that measure length. According to the International System of Units (SI) their appropriate symbols are nm and μm. Compared to the basic metric unit – the meter – the nm is one-billionth, and the μm – one-millionth of its size. Therefore, 1 micrometer is equal to 1,000 nm.

    Difference between Nanometers and Micrometers

Both units are of such small scale, that their application is strictly connected to science. Micro- and nanometers are largely used in biology or chemistry – spheres where people measure and manipulate objects at an atomic level.

A popular usage of the nanometer is in regards to electromagnetic radiation wavelength near the spectrum – most people are taught in school that visible light ranges between 400 and 700 nm. The famous physicist Albert Einstein has calculated that the sucrose molecule’s length is equal to 1 nm.

The micrometer is a unit that measures cell sizes and radiation wavelengths, and that grades wool by the diameter of its fibers. For example, typically bacteria are about 1 μm in length. A human hair ranges between 9 and 90 μm in radius, whereas that of a wool fiber can be from 5 to 28 μm.

Formerly, the micrometer would be called a micron. However, that term was revoked by the SI in 1967. The nanometer being 1/1,000 of a μm, would be referred to as millimicrometer, or millimicron.

    How to convert Nanometers to Micrometers

You can easily convert nanometers to micrometers using this formula:

nm / 1,000 = μm.

Nm to μm conversion example

Sample task: convert 5 nanometers to micrometers. Solution:

nm / 1000 = μm
5 nm / 1,000 = 0.0050 μm
End result:
5 nm is equal to 0.0050 μm
