Formula to convert inches to feet
One foot is exactly 12 inches. So to go from inches to feet, divide by 12:
| d(ft) = d(in) ÷ 12 |
To get feet and inches, divide the inches by 12: the whole part is the feet and what is left over is the inches.
To convert to centimeters, multiply the inches by 2.54. That value is exact: since 1959 the international inch has been defined as 2.54 cm.
Inches to feet examples
Example 1: How many feet is 70 inches?
d(ft) = 70 ÷ 12 ≈ 5.833 ft
To write it in feet and inches, 70 ÷ 12 gives 5 whole feet. What is left over is 70 - 12 × 5 = 10 in.
So 70 inches is 5 ft 10 in, or 177.8 cm.
Example 2: Convert 100 inches to feet
d(ft) = 100 ÷ 12 ≈ 8.333 ft
In feet and inches that is 8 ft 4 in.
Example 3: Convert 30 inches to feet
d(ft) = 30 ÷ 12 = 2.5 ft
That is 2 ft 6 in, or two and a half feet.
Example 4: Convert 5 inches to feet
d(ft) = 5 ÷ 12 ≈ 0.4167 ft
Since 5 inches is less than a foot, in feet and inches it is written 0 ft 5 in.
