To convert decimal feet to feet and inches, the whole number is feet and the decimal × 12 is inches: 5.75 ft = 5 ft + 0.75 × 12 = 5′ 9″. Going the other way, divide inches by 12: 9″ = 0.75 ft. Surveyors and engineering drawings use decimal feet; framing and finish carpentry use feet, inches and fractions.
