Inches to Feet Converter

How to convert inches to feet?

Converting inches to feet is a foundational US-customary calculation: divide inches by 12 because 1 ft is defined as exactly 12 in (and, by the 1959 international agreement, 1 in is exactly 25.4 mm and 1 ft is exactly 0.3048 m). The division is exact when the input is a multiple of 12 and otherwise yields a clean decimal-feet value, which is the form preferred in engineering drawings and CAD files. In everyday use it is also common to keep the result in feet-and-inches: floor(in/12) is the foot part, and in mod 12 is the residual inches. Three real-world places where inches-to-feet appears constantly: (a) height in the US — a 70 in person is 5 ft 10 in tall; (b) lumber and stock material, where a 96 in board is exactly 8 ft and a 144 in board is 12 ft; (c) screen size — TVs are sold by diagonal inches but room-fit calculations work in feet (a 75 in TV is 6 ft 3 in diagonal, requiring about 5 ft 6 in of horizontal wall at the standard 16:9 aspect ratio). Our converter accepts any positive or negative decimal, rounds the displayed feet to six significant figures by default, and uses IEEE-754 double-precision arithmetic, so even an input like 12.00000001 in returns 1.0000000000833333 ft rather than getting clipped.

d_(ft) = d_(in) / 12

Worked example

Convert a 75 inch TV diagonal to feet. Step 1: 75 / 12 = 6.25 ft (decimal feet). Step 2: floor(6.25) = 6 ft, residual = 0.25 × 12 = 3 in. Final: 75 in = 6.25 ft = 6 ft 3 in. To check wall fit at 16:9 aspect ratio, the horizontal width is 75 × cos(arctan(9/16)) ≈ 75 × (16/√337) ≈ 65.4 in ≈ 5 ft 5.4 in.

d_(ft) = 24in / 12 = 2ft

What is an Inch?

An inch is a unit of length in the imperial and US customary systems of measurement. It is equal to 1/12 of a foot or 1/36 of a yard. The inch is commonly used in the United States, Canada, and the United Kingdom for measuring height, distance, and other dimensions.

What is a Foot?
