# Convert Kilometers to Micrometers

## Learn How to Convert Kilometers to Micrometers Using our Conversion Formula

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 1000000000 micrometers, so to convert simply multiply by 1000000000.

For example, 5km = (5 × 1000000000) = 5,000,000,000µm.

Kilometers and micrometers are both units used to measure length. Learn more about length and

A kilometer is a metric measurement and can be abbreviated as *km*, for example 1km.
A micrometer is a metric measurement and can be abbreviated as *µm*, for example 1µm.

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.
