The feet to mm converter below can be used to quickly and easily convert feet to millimeters. Simply enter the number of feet you want to convert and the calculator will output the corresponding value in millimeters.
What is the conversion factor between feet and millimeters?
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 feet and millimeters is 304.8, such as:
Following the formula above, we can see that there are 304.8 millimeters for every foot, and for every millimeter, there are 1304.8 feet (0.00328084 ft).
To convert from feet to millimeters, we turn our formula into a conversion factor that is equal to 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 foot to millimeter, we will use the first fraction: 304.8 mm1 ft so that feet are canceled out. We then multiply the value in feet by this fraction to get the result in millimeters (see example).
Note that ft 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 ft to mm. Just remember for now that the conversion factor for converting from feet to millimeters is:
Which is bigger, a foot or a millimeter?
When it comes to measurements, there can be some confusion over which is bigger, a foot or an millimeter. To find out which one is larger, we must first convert one unit to the other and then compare them.
- 1 ft = 304.8 mm
- 304.8 millimeters is bigger than 1 millimeter.
- 1 foot is, therefore, bigger than 1 millimeter.
- To be more specific, a millimeter is 304.8 times smaller than a foot.

How to convert feet to millimeters?
Multiplying any value by 1 will get you the same value back. You can do that one time or multiple times.
For example:
- 82 x 1 = 82
- 740 x 1 x 1 x 1 = 740
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 10 feet into millimeters we multiply 10 ft by the conversion factor of 304.8 mm1 ft
By replacing the number 1 with the conversion factor, feet are canceled out and we get the result in millimeters. 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 10 feet are equal to 3048 millimeters.
Remember:
- When converting from feet to millimeters, we use 304.8 mm1 ft as a conversion factor.
