## How to Convert Kilometers to Micrometers

To convert a kilometer measurement to a micrometer measurement, multiply the length by the conversion ratio. One kilometer is equal to 1,000,000,000 micrometers, so use this simple formula to convert:

The length in micrometers is equal to the kilometers multiplied by 1,000,000,000.

**For example,**here's how to convert 5 kilometers to micrometers using the formula above.

Kilometers and micrometers are both units used to measure length. Keep reading to learn more about each unit of measure.

## Kilometers

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a ^{1}/_{299,792,458} second time interval.

The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "kilo" is the prefix for 10^{3}. Kilometers can be abbreviated as *km*, for example 1 kilometer can be written as 1 km.

## Micrometers

One micrometer is equal to one-millionth (1/1,000,000) of a meter, which is defined as the distance light travels in a vacuum in a ^{1}/_{299,792,458} second time interval.

The micrometer, or micrometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "micro" is the prefix for 10^{-6}. A micrometer is sometimes also referred to as a micron. Micrometers can be abbreviated as *µm*, for example 1 micrometer can be written as 1 µm.

To get an idea of the actual physical length of a micrometer, one human hair is 40-50 µm thick, demonstrating how small this unit of measure is.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
