A square meter (symbol: m²) is a unit of area in the International System of Units (SI), which is the metric system commonly used in many countries worldwide. It is defined as the area of a square with sides that each measure one meter in length.
To give you a visual sense of the size of a square meter, imagine a square that is one meter long on each side. It is equal to 10,000 square centimeters (cm²) or 0.0001 hectares (ha). In square feet, one square meter is approximately 10.7639 square feet (sq ft).
The square meter is the primary unit for measuring area in the metric system and is widely used in various scientific, engineering, and everyday applications for describing land area, room dimensions, and many other surface measurements.
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.
