Quick Answer
There are 12 inches in a foot, so divide inches by 12 to get feet. 24 in is 2 ft, 30 in is 2.5 ft (2 ft 6 in), 66 in is 5.5 ft (5 ft 6 in) and 100 in is 8.333 ft (8 ft 4 in). To turn feet into inches, multiply by 12: 6 ft is 72 in.

How This Inches to Feet Converter Works
Tape measures, TV sizes, heights, furniture and lumber are measured in inches, but plans and room sizes are usually in feet. Choose the direction, enter the length and press Calculate. You get decimal feet (or inches), the same length as whole feet plus inches, and yards, centimeters and meters.
Quick explanation: 12 inches make one foot.
- in to ft: divide by 12.
- ft to in: multiply by 12.
- Feet and inches: whole feet = inches ÷ 12 rounded down; the remainder is inches.
How to Use the Inches to Feet Converter
- Choose inches to feet or feet to inches.
- Enter the length.
- Press Calculate.
- Read decimal feet, whole feet and leftover inches, yards, centimeters and meters.
Inches to Feet Formulas
- Definition: 1 foot (ft) = 12 inches (in)
- Feet from inches: ft = in ÷ 12
- Inches from feet: in = ft × 12
- Split: feet = floor(in ÷ 12); inches left = in − 12 × feet
- Yards and metric: 1 yd = 36 in; 1 in = 2.54 cm exactly
Key Terms
- Inch (in): one twelfth of a foot, exactly 2.54 cm.
- Foot (ft): 12 inches, exactly 0.3048 m.
- Yard (yd): 3 feet or 36 inches.
- Decimal feet: feet written with a decimal part, such as 5.5 ft.
- Prime marks: the symbols ′ for feet and ″ for inches, as in 5′ 6″.
Worked Example
A sofa is 86 inches wide. How wide is it in feet?
- 86 ÷ 12 = 7.167 ft
- Whole feet: 7; 7 × 12 = 84 in, so 86 − 84 = 2 in left over
- The sofa is 7 ft 2 in wide, or 218.44 cm.
Going the other way, a 6.75 ft ceiling beam is 6.75 × 12 = 81 inches, which is 6 ft 9 in.
Real-Life Examples
- Height: 70 in is 5 ft 10 in.
- Rooms: 150 in of wall is 12.5 ft.
- Lumber: a 96 in board is 8 ft.
- Fabric: 54 in is 4.5 ft, or 1.5 yards.
Inch vs Foot
- Inch (in): 2.54 cm, for short lengths.
- Foot (ft): 12 inches, 30.48 cm, for rooms and heights.
- Yard (yd): 3 feet or 36 inches, for fabric and fields.

Decimal Feet vs Feet and Inches
Surveyors, engineers and many building plans write lengths in decimal feet, such as 12.25 ft, because decimals are easy to add and multiply. Carpenters and tape measures use feet and inches, such as 12 ft 3 in. Both describe the same length, but the decimal part is a fraction of a foot, not a number of inches. Multiply the decimal part by 12 to get inches: 0.25 ft × 12 = 3 in. Writing 12.25 ft as 12 ft 25 in, or reading 5.10 ft as 5 ft 10 in, is a common and costly mistake.
Inches themselves are often split into fractions on a tape measure, such as 3/8 or 5/16. If your measurement has a fraction, convert it to a decimal first (3/8 = 0.375) or use the Feet and Inches Calculator, which accepts fractions directly. For metric plans, use the centimeter and meter lines.
Common Mistakes to Avoid
- Reading 5.5 ft as 5 ft 5 in. It is 5 ft 6 in.
- Dividing by 10. A foot has 12 inches.
- Mixing ′ and ″. ′ is feet; ″ is inches.
- Ignoring fractions. 3/4 in is 0.75 in, not 0.34.
- Squaring wrong. 144 square inches make 1 square foot, not 12.
