1 square meter, denoted by the symbol m^2, is the SI derived unit of area. It represents the area of a square with each side measuring one meter. As a derived unit, the square meter is defined from the meter, the base unit of length in the International System of Units, and is used to quantify two‑dimensional size.

In practice, the square meter is used to express areas such as floor spaces, land plots, and the surface area of objects. Because area scales with length, many calculations involve multiplying length and width for rectangular shapes, yielding an area in square meters when lengths are in meters.

Common conversions include: 1 m^2 = 10,000 cm^2; 1 m^2 = 0.000001 km^2; 1 m^2 = 0.0001 hectares; 1 m^2 ≈ 10.7639 square feet; 1 m^2 ≈ 1.19599 square yards; and 1 m^2 ≈ 1550.0031 square inches. Conversely, 1 in^2 ≈ 0.00064516 m^2. These conversions facilitate measurement across metric and imperial systems.

Historical and definitional notes: the meter was redefined in 1983 in terms of the speed of light, making the square meter a derived unit tied to fundamental constants rather than a physical artifact. The unit has dimension of length squared and is used across science, engineering, construction, and everyday measurement to describe area rather than length alone.
