The conversion between inches and feet is a fundamental aspect of the Imperial and U.S. customary systems of measurement. This calculator helps you quickly and accurately convert a given number of inches into its equivalent in feet.
The Math Behind the Conversion
The relationship between inches and feet is defined by a simple, constant ratio:
There are 12 inches in 1 foot.
To convert a value from inches to feet, you divide the number of inches by 12. The formula is:
Feet = Inches / 12
Conversely, to convert feet to inches, you multiply the number of feet by 12. The formula is:
Inches = Feet * 12
This calculator focuses on the inches to feet conversion. For example, if you have 30 inches, the calculation would be 30 / 12 = 2.5 feet.
