What is Square Meters?

Square Meters (m²) is a unit of area. A square meter is the SI derived unit of area, defined by a square with sides exactly one meter long. It serves as the base unit for area in the metric system and equals 10,000 square centimeters [bipm-si-brochure]. This unit is essential for measuring surfaces in construction, real estate, and science. The meter was first defined in 1793 by the French Academy of Sciences as one ten-millionth of the distance from the equator to the North Pole. The square meter was established alongside the meter for area measurements and internationally standardized by BIPM [bipm-si-brochure]. Square meters are the primary unit of area measurement in nearly all countries using the metric system. It is common in engineering, architecture, land measurement, and many industrial sectors [bipm-si-brochure].

What is Hectares?

Hectares (ha) is a unit of area. The hectare is a metric unit of area defined as 10,000 square meters or 0.01 square kilometers. It is commonly used to measure land area in agriculture, forestry, and land management. The hectare is not an SI base unit but is accepted for use with SI units internationally [bipm-si-brochure]. The hectare was introduced in France during the metric system's creation in the late 18th century to provide a practical unit for land measurement. It was officially recognized by the International Committee for Weights and Measures as an accepted unit for area [bipm-si-brochure]. Hectares are widely used in Europe, Asia, and many countries for agricultural and environmental reporting. It is the standard unit for land parcels in official documents and maps and is preferred by organizations like the FAO and ISO [bipm-si-brochure].
