How to Convert Kilometers to Micrometers Using an Easy Conversion Formula

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

Convert kilometers to micrometers with this simple formula:

micrometers = kilometers × 1,000,000,000

Converting a kilometer length measurement to a micrometer measurement involves multiplying your length by the conversion ratio to find the result. A kilometer is equal to 1,000,000,000 micrometers, so to convert simply multiply by 1,000,000,000.

For example:
5 km = (5 × 1,000,000,000) = 5,000,000,000 µm

Kilometers and micrometers are both units used to measure length. Learn more about length and find more length measurement conversion calculators. A kilometer is a metric measurement and can be abbreviated as km, for example 1 km. A micrometer is a metric measurement and can be abbreviated as µm, for example 1 µm. 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.
