How to Convert Feet to Inches
Feet and inches are both units in the imperial measurement system, commonly used in the United States for measuring height, room dimensions, and construction. Since 12 inches equal 1 foot, the conversion is straightforward, but it's easy to make mistakes when mixing feet and inches together.
The Conversion Formula
Inches = Feet Γ 12
To convert a mixed measurement (feet and inches) to total inches:
Total Inches = (Feet Γ 12) + Inches
Step-by-Step Examples
Example 1: Convert 6 feet to inches.
- 6 Γ 12 = 72 inches
Example 2: Convert 5 feet 9 inches to total inches.
- (5 Γ 12) + 9 = 60 + 9 = 69 inches
