How to Convert Inches to Feet
Converting inches to feet uses one simple rule: there are 12 inches in 1 foot. To convert inches to feet, you divide by 12. To go the other way (feet to inches), you multiply by 12.
Step-by-step for 40 inches:
- Start with 40 inches.
- Divide by the conversion factor: 40 ÷ 12 = 3.33.
- So, 40 inches = 3.33 feet.
Reverse check (multiply method):
- 3.33 feet × 12 = 40 inches ✓
In feet and inches: 40 ÷ 12 = 3 whole feet, with a remainder of 4 inches (since 3 × 12 = 36, and 40 − 36 = 4). That gives you 3 feet 4 inches.
