About Are (a)
Definition
The are is a metric unit of area equal to 100 square meters — the area of a square with 10-meter sides.
Mathematical Relationship
1 a = 100 m² = 0.01 ha = 1 dam². 100 ares = 1 hectare.
Conversion Formula
To convert ares to m²: multiply by 100. To hectares: divide by 100. To acres: multiply by 0.0247.
Practical Applications
Small garden plots, residential lots in some European land records, and educational exercises.
Interesting Facts
The word 'hectare' literally means '100 ares.' Despite the are's obscurity, its derivative hectare is used worldwide.
Common Mistakes
Confusing 'are' with 'acre.' An are = 100 m², while an acre = 4,046.86 m² — an acre is about 40× larger.
Educational Tips
Remember: 1 are = 10 m × 10 m = 100 m². And 1 hectare = 100 ares = 10,000 m². The naming is systematic.
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.
