How to Convert Millimeters to Miles

To convert a measurement in millimeters to a measurement in miles, divide the length by the following conversion ratio: 1,609,344 millimeters/mile.

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 length in millimeters divided by 1,609,344.

For example, here's how to convert 5,000,000 millimeters to miles using the formula above.

miles = (5,000,000 mm ÷ 1,609,344) = 3.106856 mi

What Is a Millimeter?

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 ¹/_299,792,458 of a second. One millimeter is equal to 0.0393701 inches.

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 thousandths, or 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]
