How to Convert Micrometers to Kilometers

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

Convert micrometers to kilometers with this simple formula:

kilometers = micrometers × 1.0E-9

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

For example, here's how to convert 5 micrometers to kilometers using the formula above.
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. Micrometers are a metric measurement and can be abbreviated as µm, for example 1 µm. Kilometers are 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.
