Understanding Feet and Inches
The imperial system of measurement, still widely used in the United States and some other countries, utilizes two primary units of length: feet and inches. A foot (abbreviated as ‘ft’) is a unit of 12 inches, while an inch (abbreviated as ‘in’) represents a fraction of a foot. Understanding the conversion between feet and inches is crucial for various measurements and applications.

Converting Feet to Inches
Converting feet to inches is a straightforward mathematical operation that involves multiplying the number of feet by 12. For example, to convert 3 feet to inches, we multiply 3 by 12, resulting in 36 inches.
1 foot = 12 inches
Converting Inches to Feet
To convert inches to feet, we divide the number of inches by 12. For instance, to convert 48 inches to feet, we divide 48 by 12, resulting in 4 feet.
1 inch = 1/12 foot
