About Square Chains
A square chain (ch²) is a surveying unit equal to the area of a square with sides of one Gunter's chain (66 feet or ~20.12 m), approximately 404.69 m². Ten square chains equal exactly one acre, making it the natural subdivision unit in traditional land surveying. The US Public Land Survey System used chains to lay out townships and sections, and square chains appear throughout old legal property descriptions and government land grants across North America. One square chain equals exactly 16 square rods.
About Hectares
A hectare (ha) is a metric unit of area equal to 10,000 m² (100 m × 100 m). It is the primary unit for measuring agricultural land, forests, and large properties worldwide outside the United States. One hectare equals 2.471 acres. A FIFA-regulation football pitch is about 0.7 ha, and Vatican City is 44 ha. This unit is fundamental in agriculture, forestry, environmental conservation, and international land measurement standards.
