📏 Inch to Feet Converter

Remember: 12 inches = 1 foot. Type in either box and the other updates instantly. A decimal feet value like 6.5 ft also breaks down into whole feet plus remaining inches (6 ft 6 in).
| Inches (in) | Feet (ft) |

One foot equals exactly 12 inches, so this inch to feet converter divides your inch value by 12 to get feet, and multiplies feet by 12 to get inches back. Type 72 inches and it instantly shows 6 ft 0 in, or 6.0 ft as a decimal. The converter works both directions at once: edit either box and the other updates live, with a feet-and-inches breakdown alongside the decimal feet figure, so you always see the answer in whichever form you actually need.
What is the Inch to Feet Converter?
The inch and the foot are both units of length in the US customary and imperial systems, and the relationship between them has been fixed since 1959 under the international yard and pound agreement: exactly 12 inches make 1 foot, with no rounding or approximation involved. That single constant, 12, is the entire basis for every inch to feet conversion. To go from inches to feet you divide by 12; to go from feet to inches you multiply by 12. There is no messier factor to memorize, which is part of why this pairing is so common in everyday measuring, from lumber and fabric to room dimensions and human height.
Because 12 does not divide evenly into most whole numbers, converting inches to feet usually leaves a remainder, and that remainder is itself expressed in inches rather than as an awkward fraction. For example, 100 inches is not a tidy number of feet: dividing by 12 gives 8 with a remainder of 4, so the natural way to state it is 8 feet 4 inches, not "8.333 feet" on a tape measure or a set of blueprints. This inch to feet converter shows both forms side by side, the whole-feet-plus-inches breakdown for reading on a ruler or spec sheet, and the decimal feet value for calculations, spreadsheets, or anywhere a single number is more useful than a mixed unit.
The formula behind an inches to feet calculator is simple division and multiplication, but getting it wrong is a common source of measurement errors. A carpenter cutting a board to "6.5 feet" who mistakenly reads it as 6 feet 5 inches instead of 6 feet 6 inches will be off by an inch, enough to matter in finish work. Converting inches to feet correctly also matters in fields like construction, interior design, shipping (dimensional weight is often calculated in feet), and even height measurements, where a persons height in inches is routinely restated as feet and inches on forms and ID documents.
This tool is built to remove that friction entirely. Enter a value in either the inches field or the feet field of the inch to feet converter and the other field, along with the feet-and-inches breakdown, updates immediately, no page reload and no manual arithmetic. The reference chart further down covers the most commonly needed inch-to-feet conversions in 12-inch steps, so you can scan a value at a glance without typing anything at all.
When to use it
- Converting a room, board, or fabric measurement given in inches into feet for a floor plan, cut list, or quote.
- Restating a person's height in inches, such as from a medical chart, as the familiar feet-and-inches format.
- Checking a shipping or freight dimension that was recorded in inches against a feet-based size limit.
- Quickly verifying a DIY or construction measurement before cutting material, avoiding costly off-by-an-inch mistakes.
How to use the Inch to Feet Converter
- Enter a value in the "Inches" field; the default is 72 inches.
- Watch the "Feet" field and the result panel update instantly, showing both the feet-and-inches breakdown and the decimal feet value.
- Alternatively, type a value directly into the "Feet" field and the inches field will update to match.
- Use the copy button to grab the full result line, or the reset button to return to the 72-inch example.
Formula & method
Worked examples
Convert 100 inches to feet and get the feet-and-inches breakdown.
- Divide inches by 12: 100 / 12 = 8.3333 (repeating)
- The decimal feet value is 8.3333 ft
- For the whole-feet part, take the floor of 8.3333, which is 8 ft
- Find the remainder: 100 - (8 x 12) = 100 - 96 = 4 in
- Combine the parts: 8 ft 4 in
Result: 100 in = 8 ft 4 in = 8.3333 ft
Convert 5.5 feet to inches.
- Multiply feet by 12: 5.5 x 12 = 66
- There is no remainder to break out since the result is a whole number of inches
- Confirm by reversing: 66 / 12 = 5.5 ft
Result: 5.5 ft = 66 in
Inches to feet, in 12-inch steps

Common heights, feet and inches to total inches
| Feet and inches | Total inches |
|---|---|
| 5 ft 0 in | 60 in |
| 5 ft 6 in | 66 in |
| 5 ft 10 in | 70 in |
| 6 ft 0 in | 72 in |
| 6 ft 2 in | 74 in |
| 6 ft 6 in | 78 in |
Common mistakes to avoid
- Treating decimal feet as feet and inches. A value of 6.5 ft is not 6 feet 5 inches. The decimal 0.5 represents half of a foot, which is 6 inches, so 6.5 ft equals 6 ft 6 in. Always multiply the decimal part by 12 to get the correct remaining inches.
- Using 10 or 100 as the conversion factor. Because most everyday unit conversions are decimal (metric), it is easy to reach for 10 or 100 out of habit. The inch to feet relationship is fixed at 12 inches per foot, not a power of 10, so that shortcut always produces a wrong answer.
- Rounding the remainder incorrectly. When converting an odd number of inches, such as 100 in, the whole-feet part comes from flooring the division (8, not 8.33), and the leftover 4 inches must be calculated separately as inches minus (whole feet times 12), not just rounded from the decimal.
- Mixing up which field is feet and which is inches. Since 12 inches is a small number compared to feet, entering a "feet" value into the inches field (or vice versa) produces a result that is off by a factor of 12. Double-check the label above each field before reading the result.

Frequently asked questions
How many feet is 1 inch?
1 inch equals 1/12 of a foot, or about 0.0833 ft. To convert any number of inches to feet, divide that number by 12.
How do you convert inches to feet?
Divide the number of inches by 12. For example, 72 inches divided by 12 equals 6 feet. This inch to feet converter does that division automatically as you type.
How many inches are in a foot?
There are exactly 12 inches in 1 foot. This is a fixed definition, not an approximation, so 12 is always the correct number to multiply or divide by.
What is 100 inches in feet and inches?
100 inches equals 8 feet 4 inches, or 8.3333 feet as a decimal. Dividing 100 by 12 gives 8 with a remainder of 4.
How do I convert a decimal feet value like 5.5 ft to inches?
Multiply by 12: 5.5 ft x 12 = 66 inches. The same multiplication works for any decimal feet value.
Why is my height in inches different from feet and inches on my ID?
A height like 68 inches is the same measurement as 5 feet 8 inches, just written differently. Dividing 68 by 12 gives 5 with a remainder of 8, so 68 in and 5 ft 8 in describe the identical height.
