How to Convert Mil to Foot
- 1 mil = 0.00008333333333 ft
- 1 ft = 12000 mil
- Example: convert 15 mil to ft: 15 mil = 15 × 0.00008333333333 ft = 0.00125 ft
Reference conditions. ft: The international yard and pound agreement (1959) fixed 1 yard = 0.9144 m exactly, so the inch, foot and mile are exact.
Formula
ft = mil ÷ 12000
Derivation from SI units:
- 1 mil = 0.001 in = 25.4 µm (exact)
- 1 ft = 12 in = 0.3048 m (exact)
- 1 mil = 0.0000254 m ÷ 0.3048 m per ft = 0.00008333333333333 ft
Both units are defined exactly, so the factor is exact. Mil definition: mil; Foot definition: foot.
Worked examples
- A reading of 4 mil converts to 0.0003333333333 ft.
4 mil × 0.00008333333333 = 0.0003333333333 ft - A value of 15 mil is 0.00125 ft.
15 mil × 0.00008333333333 = 0.00125 ft
