Convert 123 µm to km

Converting measurements from micrometers (µm) to kilometers (km) is essential in various scientific and engineering fields. This guide provides a clear method to perform this conversion accurately.

µm Definition

Micrometer (µm) is a unit of length equal to one millionth of a meter. It is commonly used in fields such as biology, materials science, and engineering to measure small distances, such as the size of cells or the thickness of materials.

km Definition

Kilometer (km) is a unit of length in the metric system, equal to 1,000 meters. It is widely used for measuring distances in geography, transportation, and land surveying.

How to Convert 123 µm to km

To convert micrometers to kilometers, use the following formula:

1 µm = 1 x 10^-9 km

To convert 123 µm to km:

123 µm x 1 x 10^-9 km/µm = 1.23 x 10^-7 km

Therefore, 123 µm is equal to 0.000000123 km.
