20 millimeters is equivalent to 0.0656167979002625 feet.
We know (by definition) that: 1 mm ≈ 0.0032808399 ft
We can set up a proportion to solve for the number of feet.
1 mm 20 mm ≈ 0.0032808399 ft x ftNow, we cross multiply to solve for our unknown x:
x ft ≈ 20 mm 1 mm * 0.0032808399 ft → x ft ≈ 0.065616798 ftConclusion: 20 mm ≈ 0.065616798 ft
The inverse of the conversion factor is that 1 foot is equal to 15.24 times 20 millimeters.
It can also be expressed as: 20 millimeters is equal to 1 15.24 feet.
Approximation
An approximate numerical result would be: twenty millimeters is about zero point zero seven feet, or alternatively, a foot is about zero times twenty millimeters.
