# Convert Millimeters to Kilometers

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

Converting a millimeter length measurement to a kilometer measurement involves multiplying your length by the conversion ratio to find the result. A millimeter is equal to 1.0E-6 kilometers, so to convert simply multiply by 1.0E-6.

For example, 5mm = (5 × 1.0E-6) = 5.0E-6km.

Our inch fraction calculator can add millimeters and kilometers together and it also automatically converts the results to both imperial and metric values.

Millimeters and kilometers are both units used to measure length. Learn more about length and

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

Millimeter is spelled *millimetre* internationally,
and it is equal in length to .1 centimeters, 1000 micrometers, or ^{5}/_{127} inch. They are represented by the
smallest ticks on most metric rulers. To get a reference point of the size,
the thickness of a dime is 1.35mm.

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.
