Difference Between Feet and Inches
Feet and inches are both units of length measurement used in the imperial and U.S. customary measurement systems. Here are the key differences between them:
Unit Size:
- An inch is a smaller unit of length. It is used for more detailed measurements where precision is needed.
- A foot is a larger unit of length, equivalent to 12 inches. It is used for measurements that are longer than what would be convenient to measure in inches.
Usage:
- Inches are often used to measure smaller objects, like the dimensions of a book or the diameter of a pipe.
- Feet are used to measure larger distances or heights, such as the height of a person or the length of a room.
Symbol:
- The symbol for inch is in or “.
- The symbol for foot is ft or ‘.
Conversion:
- To convert from feet to inches, you multiply by 12 (since there are 12 inches in a foot).
- To convert from inches to feet, you divide by 12.
Examples:
- A person might be 6 feet (6′) tall, which is the same as 72 inches (72″).
- A laptop might be 15 inches (15″) wide, which is equivalent to 1.25 feet (1.25′).
How to Convert Feet to Inches?
To convert feet to inches, you use the conversion factor that 1 foot equals 12 inches. The formula is:
Inches = Feet × 12
Here’s how to perform the conversion:
- Determine the number of feet you want to convert to inches.

- The result is the length in inches.
For example, if you want to convert 5 feet to inches, you would calculate:
5 feet × 12 inches/foot = 60 inches
So, 5 feet is equal to 60 inches.
