### What is a Micrometer?

The **Micrometre** (SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length equalling 1×10−6 meter (SI standard prefix "micro-" = 10−6); that is, one-millionth of a meter (or one-thousandth of a millimeter, 0.001 mm, or about 0.00004 inches).

A micrometer is a standard unit of measurement used to measure wavelengths of infrared radiations, sizes of biological cells and bacteria, and for grading wool by the diameter of the fibers.

The width of a single human hair ranges from approximately 20 to 200 μm. The longest human chromosome, chromosome 1, is approximately 10 μm in length.

### What is a Kilometer?

The **Kilometre **(SI symbol: km) is a unit of length in the metric system, equal to one thousand metres (kilo- being the SI prefix for 1000).

A kilometer is a metric system unit mainly used to express distance in most of the world; notable exceptions are the United States and the United Kingdom, where the mile is the unit used. Even though kilometers and miles are used for measuring the same unit (distance), the value differs.

### How to Convert Micrometer to Kilometers?

To convert Micrometer to Kilometers, simply divide the Micrometer value by 1000000000.

The formula used to calculate Micrometer to Kilometers -

**d**_{(μm)} = **d**_{(km)} / 1000000000

The distance *d* in Kilometers (km) is equal to the distance *d* in Micrometers (μm) divided by 1000000000.

### How many Kilometers in a Micrometer

In simple terms, 1 μm is equal to 1e-09 km.

The formula used is 1/1000000000 = 1e-09(km)

### How many Micrometers in a Kilometer

1 Kilometer is equal to 1000000000 Micrometers. So we can also say that there are 1000000000 Micrometers in a Kilometer.
