About Township (township)
Definition
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.
Mathematical Relationship
1 township = 36 sections = 36 mi² = 23,040 acres ≈ 93.24 km².
Conversion Formula
To convert townships to sections: multiply by 36. To acres: multiply by 23,040. To km²: multiply by 93.24.
Practical Applications
Legal land descriptions in the western US, mineral rights boundaries, and county subdivision.
Interesting Facts
Indiana was the first state fully surveyed using the township system (1799–1834). The grid is still visible in satellite imagery.
Common Mistakes
Confusing 'township' (the survey unit = 36 mi²) with 'township' as a political subdivision, which can vary in size.
Educational Tips
A township = 6 mi × 6 mi = 36 sections. Each section = 1 mi² = 640 acres. It's a nested grid system.
About Square Mile (mi²)
Definition
The square mile is an imperial unit of area equal to the area of a square with sides of one mile (2.59 km²).
Mathematical Relationship
1 mi² = 640 acres = 27,878,400 ft² = 2.59 km² = 259 ha.
Conversion Formula
To convert mi² to km²: multiply by 2.59. To acres: multiply by 640. To hectares: multiply by 259.
Practical Applications
City areas, county sizes, population density, land surveys, and geographic comparisons.
Interesting Facts
Manhattan is about 22.8 mi². The state of Texas is 268,596 mi². Rhode Island (smallest US state) is 1,214 mi².
Common Mistakes
1 mi ≈ 1.609 km, but 1 mi² ≈ 2.59 km² (not 1.609). Area conversion squares the factor.
Educational Tips
1 mi² = 640 acres. This 'section' (640 acres) is the basis of the US Public Land Survey System grid.
