Understanding Feet and Inches
Feet and inches are part of the imperial measurement system, widely used in the United States and a few other countries.
- 1 foot = 12 inches
That’s the key number to remember.
When someone says 5 feet 8 inches, they mean:
- 5 feet
- plus 8 extra inches
To work with this measurement easily (especially in math), it’s helpful to convert everything into inches only.
Feet and Inches to Inches Formula
The formula is very simple:
Total Inches = (Feet × 12) + Inches
That’s it.
Multiply the number of feet by 12, then add the remaining inches.
Step-by-Step Examples
Example 1: Convert 5 feet 8 inches to inches
Step 1: Multiply feet by 12
5 × 12 = 60
Step 2: Add remaining inches
60 + 8 = 68
Answer: 5’8″ = 68 inches
Example 2: Convert 6 feet 2 inches to inches
6 × 12 = 72
72 + 2 = 74
Answer: 6’2″ = 74 inches
Example 3: Convert 4 feet 0 inches to inches
4 × 12 = 48
48 + 0 = 48
Answer: 4’0″ = 48 inches

Reverse Conversion (Inches to Feet and Inches)
If you ever need to convert back:
- Divide total inches by 12.
- The whole number is feet.

Example:
68 ÷ 12 = 5 remainder 8
So 68 inches = 5 feet 8 inches.
