Whether you're helping your child with homework or just curious yourself, knowing how to convert between different units of measurement is an important skill. One common conversion question is "How many feet are in a mile?" Keep reading for the simple answer and tips on how to easily convert from miles to feet.
The simple answer
The simple answer to how many feet are in a mile is 5,280 feet. This can be useful when trying to estimate distances or understand scale in maps and models.
Converting from miles to feet
If you need a more precise measurement or are converting between different units of measurement, here's how to convert from miles to feet:
Step 1: Write down the number of miles you want to convert. For example, let's use 3 miles.
Step 2: Multiply that number by the conversion factor. One mile = 5,280 feet. So, multiply 3 miles by 5,280 feet.
Step 3: Calculate the answer. In this case, the answer is 15,840 feet (3 x 5,280 = 15,840).
Other common unit conversions
In addition to converting between miles and feet, here are some other common unit conversions you may come across:
Inches to feet: 12 inches = 1 foot
Feet to yards: 3 feet = 1 yard

Why are there 5,280 feet in a mile?
The origin of this conversion can be traced back to Roman times when the Romans used a measurement called "mille passus," which translates to "a thousand paces." Since a pace was roughly equivalent to five human feet from heel to toe in Roman times, it was equivalent to about 5,000 feet or roughly one mile.
So where does that extra 280 feet come from? You can thank the British. In the late 1590s, Parliament wanted to standardize the mile better. So they made it equivalent to eight “furlongs,” which are used in racing. One furlong = 660 feet. And 660 feet times eight = 5,280.
How the mile compares to the kilometer
While the mile is a commonly used unit of measurement in the U.S., most other countries use the metric system and measure distance in kilometers. Here's how they compare:
1 mile = 1.60934 kilometers
This means that one kilometer is roughly 0.62 miles. To convert from kilometers to miles, simply multiply the number of kilometers by 0.62.
Now that you know how many feet are in a mile, you can impress your friends and family with this fun fact or use it to calculate distances on your next road trip. Keep practicing and soon you'll be a pro at converting between different units.
