To convert km² to mi²: multiply by 0.3861. To hectares: multiply by 100. To acres: multiply by 247.105.
1 km² = 1,000,000 m² = 100 ha = 247.105 acres ≈ 0.3861 mi².
For example, 1 Square Kilometer (km²) = 0.01072505996 Township (township).

The square kilometer is a metric unit of area equal to 1,000,000 square meters, or a square with sides of 1 kilometer.
1 km² = 1,000,000 m² = 100 ha = 247.105 acres ≈ 0.3861 mi².
To convert km² to mi²: multiply by 0.3861. To hectares: multiply by 100. To acres: multiply by 247.105.
Country areas, national park sizes, city footprints, forest coverage, and watershed boundaries.
Vatican City = 0.44 km². Manhattan = 59.1 km². Russia = 17,098,242 km² (largest country). Earth's surface = 510,072,000 km².
Thinking 1 km² = 1,000 m² (it's actually 1,000,000 m²). Area scales as the square of the linear dimension.
1 km = 1,000 m, but 1 km² = 1,000² m² = 1,000,000 m². Always square the conversion factor for area.
A township (survey) is a unit of land area equal to 36 square miles (93.24 km²), used in the US Public Land Survey System.
1 township = 36 sections = 36 mi² = 23,040 acres ≈ 93.24 km².
To convert townships to sections: multiply by 36. To acres: multiply by 23,040. To km²: multiply by 93.24.
Legal land descriptions in the western US, mineral rights boundaries, and county subdivision.
Indiana was the first state fully surveyed using the township system (1799–1834). The grid is still visible in satellite imagery.
Confusing 'township' (the survey unit = 36 mi²) with 'township' as a political subdivision, which can vary in size.
A township = 6 mi × 6 mi = 36 sections. Each section = 1 mi² = 640 acres. It's a nested grid system.
