Converting inches to feet is one of the most basic and practical length conversions. Whether you're measuring furniture, calculating distances, or reading specifications, understanding this relationship is fundamental to working with US measurements.
The Conversion Formula
One foot equals exactly 12 inches. This is a fixed relationship used consistently throughout US measurements and engineering standards.
1 foot = 12 inches
1 inch = 0.083333 feet
To convert inches to feet, divide by 12:
Feet = Inches รท 12
Worked Examples
Example 1: Convert 24 inches to feet

Quick Reference Table
| Inches | Feet | Common Reference |
|---|---|---|
| 6 | 0.5 | Half a foot |
| 12 | 1 | Standard ruler |
| 18 | 1.5 | 1.5 feet |
| 24 | 2 | Door width |
| 36 | 3 | Yard measurement |
| 48 | 4 | Standard height |
| 60 | 5 | Person height |

Converting Feet Back to Inches
To find how many inches are in feet:
Inches = Feet ร 12
Example: 7 feet to inches:
7 ร 12 = 84 inches
Feet and Inches Combined
Many measurements use both feet and inches together, like height. When you see 5'10" (five feet ten inches), you're looking at a mixed format.
To convert mixed format to total inches:
- Multiply feet by 12
- Add any remaining inches
Example: 6'2" to inches:
(6 ร 12) + 2 = 72 + 2 = 74 inches
To convert total inches to feet and inches:
- Divide inches by 12
- The quotient is feet
- The remainder is inches
Example: 90 inches to feet and inches:
90 รท 12 = 7 feet, 6 inches (or 7'6")
