How to convert millimeters to feet+inches

1 millimeter is equal to 0.0032808 feet:

1 mm = 0.0032808 ft

1 millimeter is equal to 0.03937 inches:

1 mm = 0.03937 in

The total distance d in inches (in) is equal to the distance d in millimeters (mm) divided by 25.4:

d_{(in) total} = d_(mm) / 25.4

The distance d in feet (ft) is equal to the floor value of the distance d in inches (in) divided by 12:

d_(ft) = ⌊d_{(in) total} / 12⌋

The distance d in inches (in) is equal to the total distance d in inches (in) minus 12 times the distance d in feet (ft):

d_(in) = d_{(in) total} – 12 × d_(ft)

Example

Convert 400 millimeters to feet+inches:

d_{(in) total} = 400mm / 25.4 = 15.748in

d_(ft) = ⌊15.748in / 12⌋ = 1ft

d_(in) = 15.748in – 12 × 1ft = 3.748in

d_(ft+in) = 1ft + 3.748in
