Common Measurement Systems
Metric System (SI)
The metric system uses square meters (m²) as the base unit for area, with various prefixes to indicate different scales.
- Square millimeter (mm²): 0.000001 m²
- Square centimeter (cm²): 0.0001 m²
- Square meter (m²): Base unit
- Square kilometer (km²): 1,000,000 m²
- Hectare (ha): 10,000 m² - commonly used for land area
- Are (a): 100 m² - less common but still used in some contexts
Imperial/US Customary System
The imperial system uses several different units for area measurements:
- Square inch (in²): 0.00064516 m²
- Square foot (ft²): 0.09290304 m²
- Square yard (yd²): 0.83612736 m²
- Square mile (mi²): 2,589,988.11 m²
- Acre (ac): 4,046.8564224 m² - commonly used for land area
Land Survey Units
These specialized units are often used in land surveying and property descriptions:
- Township: 36 square miles or about 93.24 km²
- Section: 1 square mile or about 2.59 km²
- Quarter Section: 0.25 square miles or about 0.65 km²
- Homestead: 160 acres or about 0.65 km²
- Rood: 1,011.7141056 m² or about 1/4 acre
- Square Chain: 404.6856422 m²
Scientific Units
Some specialized units are used in scientific contexts:
- Barn (b): 10⁻²⁸ m² - used in nuclear physics for cross-sectional area
- Circular Mil: 5.067×10⁻¹⁰ m² - used in electrical engineering
