Miles and millimeters both measure length, but you’d use them in different situations. For example, you wouldn’t use millimeters to measure the distance between two cities, and you wouldn’t use miles to measure the thickness of a phone case.
This article offers a simple guide on how to convert miles to millimeters, including the conversion factor and some helpful examples.
Understanding the Units: Miles and Millimeters
Before we dive into the conversion, let’s make sure we’re all on the same page about what miles and millimeters actually are.
What is a Mile?
The mile is a unit of length commonly used in the United States and the United Kingdom. It’s got historical roots that go way back, and its length is approximately:
- 5,280 feet
- 1,760 yards
- 1,609.344 meters
What is a Millimeter?
The millimeter is a unit of length in the metric system. As the name suggests, it’s one-thousandth of a meter, making it a pretty tiny unit. To give you a sense of scale, a U.S. dime is about 1.35 millimeters thick. Also:
- 1 millimeter = 0.0393701 inches
The conversion factor: Miles to Millimeters
When converting between miles and millimeters, it’s essential to know the conversion factor:
1 mile = 1,609,344 millimeters
This number is the backbone of any accurate calculation. You must use the right conversion factor. Otherwise, your estimate will be off by a lot.
To convert from miles to millimeters, use this formula:
Millimeters = Miles × 1,609,344
Practical examples of miles to millimeters conversion
Let’s walk through a couple of examples of how to convert miles to millimeters.
Example 1: Converting 5 miles to millimeters
Here’s how to convert 5 miles to millimeters using the formula we discussed above:
Millimeters = (5 mi × 1,609,344) = 8,046,720 mm
Example 2: Converting a fraction of a mile
Now let’s convert one-half of a mile to millimeters:
Millimeters = (0.5 mi × 1,609,344) = 804,672 mm
Wrapping Up
To convert from miles to millimeters, just remember: 1 mile equals 1,609,344 millimeters. So, to convert miles to millimeters, multiply the number of miles by 1,609,344.
