In Colombia, land is primarily measured in hectares (ha), a metric unit equivalent to 10,000 square meters or 2.471 acres. Smaller areas may be measured in square meters (m²). Additionally, the Colombian varas (an old Spanish unit) is sometimes used in rural areas, with 1 vara equaling 0.836 meters. It's important to be aware of these measurement units when buying, selling, or developing property in Colombia to ensure accurate and clear communication with local real estate professionals.
