ha — The hectare is a metric unit of area equal to exactly 10,000 square meters, or equivalently 100 ares. It represents the area of a square with sides of 100 meters.
The hectare is accepted for use with the International System of Units (SI) and is listed in the BIPM SI Brochure as a non-SI unit whose use is expected to continue indefinitely. It is the primary unit for reporting land area in most countries worldwide.
In agriculture, forestry, urban planning, and environmental science, the hectare serves as the standard measure for expressing the extent of land parcels, forests, and protected areas.

mi² — The square mile is a unit of area in the US customary and British imperial systems. It is defined as the area of a square with sides of exactly 1 statute mile (1,609.344 meters), giving an exact metric equivalent of 2,589,988.110336 m².
The square mile is the standard unit for expressing large land areas in the United States and the United Kingdom, commonly used in geography, census data, real estate for large tracts, and municipal planning.
One square mile equals exactly 640 acres, a relationship established by statute. It also equals exactly 3,097,600 square yards or 27,878,400 square feet.

- 0.84 mi² = 537.6 ac
- 5.2 mi² = 13.468 km²
About the Hectare
Facts & Uses
- 1 hectare = 10,000 m² = 0.01 km² exactly. The practical metric unit for land and agricultural areas — 100 m × 100 m square.
- Standard for agriculture worldwide outside the US: crop yields (tonnes/ha), farm sizes, vineyards, orchards, ranches.
- Used in forestry (timber harvest tracking), land conservation (protected areas), and European real estate (rural and large estates).
- Reference: a football pitch (FIFA standard) is about 0.7 hectares; a square 100 m on each side = 1 hectare exactly.
Curiosities
- The hectare is not part of the SI, but accepted for use with it — like the liter, it persists because of its convenient scale for everyday land measurement.
- A typical US suburban lot (1/4 acre) is about 0.1 hectare; a French vineyard for fine wine averages 5-15 hectares.
- The EU Common Agricultural Policy (CAP) distributes agricultural subsidies primarily on a per-hectare basis — making it the unit of European farm economics.
- Approximate equivalents: 1 hectare ≈ 2.4711 acres = 10,000 m² = 0.00386 mi².

About the Square Mile
Facts & Uses
- 1 mi² = 2.589988110336 km² exactly = 640 acres. The standard US/UK unit for large geographic areas.
- Standard in US geography: state and county sizes, national park areas, urban land use, agricultural surveys.
- Used in US Census data for population density (people/mi²), weather coverage areas, and federal land management.
- Reference: Manhattan is about 22.8 mi²; Los Angeles ≈ 469 mi²; Texas ≈ 268,597 mi²; Alaska ≈ 663,267 mi².
Curiosities
- The US Public Land Survey System (PLSS) divides land into 36-square-mile townships, each township subdivided into 36 sections of 1 mi² (640 acres) — the basis for rural land descriptions in 30+ states.
- The Great Lakes have a combined surface area of about 94,250 mi² (244,106 km²) — more than the entire UK.
- 1 mi² = 640 acres exactly — a clean number because the acre was historically defined as 1/640 of a square mile in the colonial English land system.
- Approximate equivalents: 1 mi² ≈ 2.59 km² = 640 acres = 27,878,400 ft².
