Micrometers to Kilometers Conversion
Enter the length in micrometers below to get the value converted to kilometers.
How to Convert Micrometers to Kilometers
To convert a micrometer measurement to a kilometer measurement, divide 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 kilometers is equal to the micrometers divided by 1,000,000,000.
Micrometers and kilometers are both units used to measure length. Keep reading to learn more about each unit of measure.
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.
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 103. Kilometers can be abbreviated as km, for example 1 kilometer can be written as 1 km.
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.
