A square foot (sq ft or ft²) is a unit of area commonly used in the United States and some other countries that use the imperial system of measurements. It is defined as the area of a square with sides that each measure one foot (12 inches) in length.
In terms of square meters, one square foot is approximately equal to 0.092903 square meters.
Square feet are frequently used to measure the area of rooms in houses, apartments, and other real estate properties. They are also used for various purposes in construction, architecture, and interior design.
The "square foot (US survey)" is a unit of area used in the United States primarily for land surveying and mapping purposes. It differs from the standard square foot because it is based on the U.S. survey foot, which is a historical unit of length used in land surveying in the United States. The U.S. survey foot is slightly different from the international foot.
One square foot (US survey) is equal to approximately 0.0929034119223 square meters (m²) or about 0.111111 square yards (yd²).
This unit is used in various land-related applications, particularly in the United States, where the U.S. survey foot and the square foot (US survey) are still employed for legal and historical reasons in certain land surveys and property descriptions. It's essential to be aware of the specific units being used when dealing with land measurements to avoid any discrepancies or errors.
