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.
A square pole, also known as a square perch, is an obsolete unit of land area measurement that was historically used in some English-speaking countries, including the United States and the United Kingdom. It is part of the older system of land measurement.
One square pole is equivalent to one square perch. In terms of modern measurements, one square pole is approximately equal to 25.29285264 square meters (m²) or 0.00625 acres.
As with other outdated units of land area measurement, the square pole is no longer commonly used in modern land transactions or legal documents. More standardized systems of measurement, such as square meters and square feet, have largely replaced these units.
