How Many Inches in a Foot?
The quick answer, a full feet-to-inches chart, the inches-to-feet method, and metric equivalents.

There are 12 inches in 1 foot. This is an exact, defined relationship in the imperial and US customary systems — not a rounded value. To convert feet to inches you multiply by 12; to convert inches to feet you divide by 12. That single number, 12, handles every conversion between these two units.
The relationship holds at any scale. Two feet is 24 inches, ten feet is 120 inches, and half a foot is 6 inches. Because the factor never changes, you can do most of the math in your head.
Feet to Inches Chart
Multiply feet by 12 to get inches. The table below covers the most common values from 1 to 12 feet.
| Feet (ft) | Inches (in) |
|---|---|
| 1 ft | 12 in |
| 2 ft | 24 in |
| 3 ft | 36 in |
| 4 ft | 48 in |
| 5 ft | 60 in |
| 6 ft | 72 in |
| 7 ft | 84 in |
| 8 ft | 96 in |
| 9 ft | 108 in |
| 10 ft | 120 in |
| 11 ft | 132 in |
| 12 ft | 144 in |
Inches to Feet
To go the other way, divide the number of inches by 12. The whole-number result is the feet, and anything left over is the remaining inches. For example, 30 inches ÷ 12 = 2 with a remainder of 6, so 30 in = 2 ft 6 in.
A few more worked examples: 18 in = 1 ft 6 in, 48 in = 4 ft exactly, and 100 in = 8 ft 4 in. When the inches divide evenly by 12, there is no remainder — otherwise the leftover stays in inches.
Metric Equivalents
If you need centimeters, both units have exact metric definitions: 1 foot = 30.48 cm and 1 inch = 2.54 cm. These figures are defined exactly by international agreement, so they are reliable for engineering and scientific work.
That means a 6-foot measurement equals 182.88 cm, and a 12-inch ruler is exactly 30.48 cm long. Multiply feet by 30.48 or inches by 2.54 to convert directly into centimeters.
