How to Convert Millimeters to Miles

To convert a millimeter measurement to a mile measurement, divide the length by the conversion ratio.

Since one mile is equal to 1,609,344 millimeters, you can use this simple formula to convert:

miles = millimeters ÷ 1,609,344

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

For example, here's how to convert 5,000,000 millimeters to miles using the formula above.
5,000,000 mm = (5,000,000 ÷ 1,609,344) = 3.106856 mi

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


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.[1]


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.

The mile is a US customary and imperial unit of length. Miles can be abbreviated as mi, and are also sometimes abbreviated as m. For example, 1 mile can be written as 1 mi or 1 m.

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.
