Accurate conversion between inches (in) and feet (ft) — instant results every time
Convert inches to feet instantly with precise calculations. Includes reverse feet to inches conversion, decimal feet, feet & inches format, full formula reference, and quick-reference conversion tables for 2026.
Fast and reliable length conversion for construction, design, everyday measurement, and more
Convert inches to feet using the exact formula: feet = inches ÷ 12. One foot equals exactly 12 inches by definition in the imperial system. Our tool outputs decimal feet, the feet-and-inches format (e.g., 5′ 7″), centimetres, and metres — giving you a complete multi-unit breakdown in one step.
Switch seamlessly between inches → feet and feet → inches conversion modes. Whether you are reading a tape measure in inches and need the equivalent in feet, or working from a plan dimension in feet and need the inch value, both directions are handled instantly from a single input value.
Essential for construction, carpentry, interior design, home improvement, real estate, and engineering. Knowing how to convert inches to feet quickly is also important in everyday tasks such as measuring furniture, calculating ceiling heights, reading blueprints, and understanding product dimensions listed in mixed units in 2026.

The inch and the foot are both units in the imperial (US customary) measurement system. The relationship between them is fixed and exact: 1 foot = 12 inches. This definition has been standardised internationally since 1959. To convert inches to feet you simply divide by 12, and to convert feet to inches you multiply by 12. For everyday measurements such as height, room dimensions, or lumber lengths, this is all you need to know.
For example, to convert 72 inches to feet: 72 ÷ 12 = 6 feet exactly. To convert 5.75 feet to inches: 5.75 × 12 = 69 inches. When a result in decimal feet needs to be expressed in feet-and-inches format, multiply the decimal part by 12 to get the remaining inches — e.g., 5.583 feet → 5 feet + (0.583 × 12) = 5 feet 7 inches.
To quickly estimate feet from inches, divide by 10 then add 20% back — or just remember the key benchmarks: 12 in = 1 ft, 24 in = 2 ft, 36 in = 3 ft, 60 in = 5 ft, 72 in = 6 ft. For precise work always use the ÷ 12 formula or the converter above.

Exactly 12 inches make one foot — this is the cornerstone of the imperial length system. The definition is internationally standardised: 1 international inch = 25.4 mm exactly, so 1 foot = 304.8 mm exactly. There is no rounding involved in the inch-to-foot relationship.
Average adult height is commonly expressed in feet and inches. 5 feet = 60 inches, 5′ 6″ = 66 inches, 6 feet = 72 inches. Understanding the conversion between units is essential when reading medical charts, clothing size guides, or international product specifications.
In construction, measurements are frequently given in feet and inches on plans but need to be converted to decimal feet for calculations. For example, a wall that is 8 feet 6 inches tall is 8.5 feet in decimal form (6 ÷ 12 = 0.5). This tool handles both formats automatically.
A common mistake is confusing decimal feet with the feet-and-inches format. For example, 5.5 feet is not 5 feet 5 inches — it is 5 feet 6 inches (because 0.5 × 12 = 6). Always use the feet-and-inches output from our converter when you need the split format.
Inches and feet are both standard units in the US customary and British imperial systems. Converting between them is a daily need in many industries and everyday situations. Below are the most common real-world applications where accurate inches to feet conversion is critical.
Blueprints, lumber sizing, door frames, and window openings are all specified in feet and inches. Builders switch between decimal feet for calculations and feet-and-inches for marking physical measurements on timber and concrete formwork.
Furniture dimensions from manufacturers often list width, height, and depth in inches, while room floor plans are drawn in feet. Accurate conversion ensures furniture fits the intended space. A 96-inch sofa, for example, is exactly 8 feet — important for room planning.
Patient height is recorded in feet and inches in the US and UK but stored in decimal form in electronic records. Converting between formats is routine for nurses, physiotherapists, and dietitians calculating body mass index (BMI) or dosing by body surface area.
Aircraft ceiling heights, runway distances, and structural clearances are all measured in feet. Equipment specifications, on the other hand, may be listed in inches. Accurate inches to feet conversion prevents costly errors in safety-critical calculations.
