How to convert decimal feet

  1. Whole feet: 1 ft
  2. Decimal part × 12: 0.75 × 12 = 9"
  3. Whole inches: 9" with 0" left over
  4. Leftover × 16: 0 × 16 = 0 → round to 0/16"
  5. Reduce and combine: 1' 9"

Trade pro tips

  • Surveys, plans and laser measures often give decimal feet — never read 0.5 ft as 5 inches (it’s 6").
  • Quick memory aid: 0.1 ft ≈ 1-3/16", 0.25 ft = 3", 0.5 ft = 6", 0.75 ft = 9".
  • Mark with a crow’s foot (V) so the point lands exactly on the fraction.
