# Convert Kilometers (km) to Micrometers (μm)

Please provide the values below to convert from Kilometer (km) to Micrometers (μm) and vice versa.

### 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.

### 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.

### How to Convert Kilometer to Micrometers?

To convert Kilometer to Micrometers, simply multiply the Kilometer value by 1000000000.

The formula used to calculate Kilometer to Micrometers -

d(km) = d(μm) * 1000000000

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

### How many Micrometers in a Kilometer

In simple terms, 1 km is equal to 1000000000 μm.

The formula used is 1*1000000000 = 1000000000(μm)

### How many Kilometers in a Micrometer

1 Micrometer is equal to 1e-09 Kilometers. So we can also say that there are 1e-09 Kilometers in a Micrometer.
