## How many feet (ft) are in 1 millimeter (mm)? What is the formula for how to convert feet to millimeters (ft to mm)?

**1 foot (ft) = 304.8 millimeters (mm)**

So we can say that there are 304.8 millimeters in 1 foot.

This means that the multiplication conversion factor to convert a quantity expressed in a foot unit of measurement to an equivalent quantity expressed in a millimeter unit of measurement is 304.8.

Inversely (or reciprocally),

**1 millimeter (mm) = 0.0032808398950131 foot (ft)**

So we can say that there is 0.0032808398950131 foot in 1 millimeter.

This means that the division conversion factor to convert a quantity expressed in a foot unit of measurement to an equivalent quantity expressed in a millimeter unit of measurement is 0.0032808398950131.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in feet to an equivalent quantity of length expressed in millimeters (ft to mm). Both formulas will yield the same result. The formulas are:

mm = ft × 304.8→ This is the formula based on the multiplication conversion factor.

and

mm = ft ÷ 0.0032808398950131→ This is the formula based on the division conversion factor.

For example, if you have a length of 6.5 feet that you want to convert to millimeters, you would use either of the two formulas as follows:

mm = 6.5 ft × 304.8 = 1,981.2 mm

mm = 6.5 ft ÷ 0.0032808398950131 = 1,981.2 mm

So, the result is the same using either formula, which is 1,981.2 millimeters.
