The Square Foot (ft²) in Area

What is Square foot (ft²)

A square foot (ft²) is a unit of area commonly used in the United States and other countries that use the imperial measurement system. It is defined as the area of a square with sides that each measure one foot (1 ft). The square foot is a practical measurement for smaller areas such as rooms, buildings, and land.

Since one foot equals 0.3048 meters, the square foot can also be expressed in metric units. To calculate the area in square meters, you multiply the length and width in meters. Thus, the conversion from square feet to square meters is given by the formula:
