What is the conversion factor between miles and feet?

A conversion factor is used to change the units of a measured quantity without changing its value. It represents the ratio (or fraction) that expresses the relationship between two different units. A conversion factor is always equal to 1.

The relationship between miles and feet is 5280, such as:

1 mi = 5280 ft

Following the formula above, we can see that there are 5280 feet for every mile, and for every foot, there are 15280 miles (0.000189394 mi).

To convert from miles to feet, we turn our formula into a conversion factor that is equal to 1.

5280 ft1 mi = 1 mi5280 ft= 1

Both these fractions are equal to 1. The numerator and the denominator are equivalent, they are just expressed in different units.

Because we are converting from mile to foot, we will use the first fraction: 5280 ft1 mi so that miles are canceled out. We then multiply the value in miles by this fraction to get the result in feet (see example).

Note that mi is in the denominator (bottom) of the conversion factor. This is important, you always want to have the unit you are converting from at the bottom and the unit you are converting to in the numerator (top).

You will find below how to use this ratio to convert from mi to ft. Just remember for now that the conversion factor for converting from miles to feet is:

5280 ft1 mi

Which is bigger, a mile or a foot?

When it comes to measurements, there can be some confusion over which is bigger, a mile or an foot. To find out which one is larger, we must first convert one unit to the other and then compare them.

  • 1 mi = 5280 ft
  • 5280 feet is bigger than 1 foot.
  • 1 mile is, therefore, bigger than 1 foot.
  • To be more specific, a foot is 5280 times smaller than a mile.

How to convert miles to feet?

Multiplying any value by 1 will get you the same value back. You can do that one time or multiple times.

For example:

  • 7 x 1 = 7
  • 983 x 1 x 1 x 1 = 983

Multiplying by 1 is the first step in any unit conversion problem. The second step is to replace the number 1 with the conversion factor that is also equal to 1.

For example, if we want to convert 0.001 miles into feet we multiply 0.001 mi by the conversion factor of 5280 ft1 mi

0.001 mi = 0.001 mi x 1 = 0.001 mi x 5280 ft1 mi = 5.28 ft

By replacing the number 1 with the conversion factor, miles are canceled out and we get the result in feet. And since the conversion factor is equal to 1, multiplying it with the original value won't change its magnitude and will only change its unit.

Based on this, we can conclude that 0.001 miles are equal to 5.28 feet.

Remember:

  • When converting from miles to feet, we use 5280 ft1 mi as a conversion factor.

Once you are confident you can convert miles to feet, there is no harm then in taking full advantage of the tools available to you.

How to convert 100 miles to feet?

We multiply 100 by the factor of 1

100 mi = 100 mi x 1

We replace the number 1 with the conversion factor for miles to feet

100 mi = 100 mi x 5280 ft1 mi

We multiply 100 miles by the conversion factor. Having miles in the denominator allows us to cancel out the undesired units (mi) leaving only feet in the final result.

100 mi = 100 mi x 5280 ft1 mi
100 mi = 100 x 52801 ft
100 mi = 528000 ft

Answer: There are 528000 feet in 100 miles

How many feet are in 715 miles?

Multiply 715 by the conversion factor. Make sure the unwanted unit (mi) is in the denominator.

715 mi = 715 mi x 5280 ft1 mi

This allows us to cancel out the miles (mi) and leave the feet (ft)

715 mi = 715 mi x 5280 ft1 mi
715 mi = 715 x 52801 ft
715 mi = 3.7752e+6 ft

Answer: There are 3.7752e+6 feet in 715 miles
