How many millimeters are there in a foot?

1 foot contains 304.8 millimeters. Alternatively, 1 millimeter is equal to 0.0032808 feet.

Feet and millimeters are units of distance or length. However, millimeters belong to the metric system and feet belong to the imperial system.

We can represent millimeters using the abbreviation mm and feet using the abbreviation ft or the symbol ′.

How to convert from feet to millimeters?

To convert from feet to millimeters, we can multiply them by 304.8. Therefore, we can form the following formula:

d(mm) = d(ft)×304.8

Example 1:

Find the number of millimeters that are equal to 3 feet.

To find the number of millimeters, we have to multiply the feet by 304.8. Therefore, we have:

d(mm) = 3×304.8

d(mm) = 914.4 mm

Example 2:

How many millimeters equal 5 feet?

By multiplying feet by 304.8, we have:

d(mm) = 5×304.8

d(mm) = 1524 mm

Example 3:

Determine the number of millimeters that are equal to 7.5 feet.

Multiplying feet by 304.8, we get:

d(mm) = 7.5×304.8

d(mm) = 2286 mm
