Square feet意思

"Square feet" (ft²) is a unit of area measurement commonly used in the United States and other countries influenced by U.S. customary units. It is used to measure the area of a two-dimensional space, such as a floor, a wall, or a piece of land. The term "square" in this context means the area is measured in feet multiplied by itself (feet times feet).

For example, a room that measures 10 feet by 10 feet would have an area of 100 square feet (10 feet x 10 feet = 100 square feet). When discussing real estate, square footage is often used to indicate the size of a home or apartment.

In the International System of Units (SI), the standard unit of area is the square meter (m²). However, square feet is still widely used in many countries for practical and historical reasons.
