How to Convert Township to Square Millimeter
To convert townships to sections: multiply by 36. To acres: multiply by 23,040. To km²: multiply by 93.24.
1 township = 36 sections = 36 mi² = 23,040 acres ≈ 93.24 km².
For example, 1 Township (township) = 9.323957e+13 Square Millimeter (mm²).

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 Millimeter (mm²)
Definition
The square millimeter is a metric unit of area equal to 10⁻⁶ square meters, or the area of a square 1 mm on each side.
Mathematical Relationship
1 mm² = 0.01 cm² = 10⁻⁶ m². There are 1,000,000 mm² in 1 m².
Conversion Formula
To convert mm² to cm²: divide by 100. To in²: multiply by 0.00155.
Practical Applications
Wire gauge cross-sections, solder pad sizes on PCBs, precision machined surface areas, and needle gauges.
Interesting Facts
A standard 14 AWG electrical wire has a cross-section of about 2.08 mm². The period at the end of this sentence covers about 0.25 mm².
Common Mistakes
Confusing mm² with mm — wire is specified by cross-sectional area (mm²), not diameter. A 2.5 mm² wire has ~1.78 mm diameter.
Educational Tips
In Europe, electrical wire is sized by mm² (cross-section area). The US uses AWG gauge numbers instead.
