Inches to Feet (in to ft) - Definition, Examples, Quiz, FAQ, Trivia
Learn to convert between inches and feet with easy explanations and practice activities
What is Length Conversion?
Length conversion means changing a measurement from one unit to another. In this lesson, we're learning how to convert between inches and feet (both used in the imperial system).
Why do we need to convert? Sometimes we measure things in inches, but it's more helpful to know the measurement in feet. For example, when measuring a room's length, feet might be more useful than inches.
One foot equals 12 inches. To convert inches to feet, we divide the number of inches by 12. Understanding this relationship helps us compare measurements and solve real-world problems.
Key Concept
1 foot = 12 inches. This relationship is the foundation for all inch-to-feet conversions.
How to Convert Inches to Feet
Converting inches to feet is simple once you remember the conversion factor:
Conversion Formula
To convert any measurement in inches to feet, divide the number of inches by 12.
Example: Convert 36 inches to feet
Step 1: Start with the measurement in inches → 36 inches
Step 2: Divide by 12 → 36 ÷ 12
Step 3: Calculate the result → 3 feet
So 36 inches equals 3 feet. It's that simple!
Remember
When converting inches to feet, your answer will be a smaller number because feet are larger units than inches.

Real-World Examples
Let's practice conversion with some real-world examples:
Example 1: A standard ruler is 12 inches long. How long is it in feet?
Solution: 12 ÷ 12 = 1 foot
Example 2: A yardstick is 36 inches long. What is this length in feet?
Solution: 36 ÷ 12 = 3 feet
Example 3: A desk is 48 inches tall. Convert this height to feet.
Solution: 48 ÷ 12 = 4 feet
Example 4: A basketball player is 6.5 feet tall. How many inches is this?
Solution: To convert feet to inches, multiply by 12: 6.5 × 12 = 78 inches
Practice converting measurements you see around you - your height, the length of your room, or the size of your TV!
Conversion Tip
