Convert micrometers to kilometers with this simple formula:

kilometers = micrometers × 1.0E-9

Converting a micrometer length measurement to a kilometer measurement involves multiplying your length by the conversion ratio to find the result. A micrometer is equal to 1.0E-9 kilometers, so to convert simply multiply by 1.0E-9.

For example:

5 µm = (5 × 1.0E-9) = 5.0E-9 km

Micrometers and kilometers are both units used to measure length. Learn more about length and find more length measurement conversion calculators. A micrometer is a metric measurement and can be abbreviated as µm, for example 1 µm. A kilometer is a metric measurement and can be abbreviated as km, for example 1 km. Learn more about the metric system, including the common unit prefixes and how to convert between metric units.

A human hair is 40-50 micrometers thick or 0.000001 meters, making this a very small unit of measure. The micrometer is often referred to as a micron and internationally it is spelled micrometre.

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.
