How to Convert Miles to Millimeters

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

To convert a mile measurement to a millimeter measurement, multiply the length by the conversion ratio. One mile is equal to 1,609,344 millimeters, so use this simple formula to convert:

millimeters = miles × 1,609,344

The length in millimeters is equal to the miles multiplied by 1,609,344.

For example, here's how to convert 5 miles to millimeters using the formula above.
5 mi = (5 × 1,609,344) = 8,046,720 mm

Our inch fraction calculator can add miles and millimeters together and it also automatically converts the results to US customary, imperial and SI metric values.

Miles and millimeters are both units used to measure length. Keep reading to learn more about each unit of measure.


The mile is a linear measurement of length equal to exactly 1,609.344 meters. One mile is also equal to 5,280 feet or 1,760 yards.

One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10-3. Millimeters can be abbreviated as mm, for example 1 millimeter can be written as 1 mm.

Millimeters are often represented by the smallest ticks on most metric rulers. To get a reference point of the size, the thickness of a US 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.
