Understanding Area Measurement Systems

Metric System (SI)

Based on square meters and powers of 10

  • • Square millimeter (mm²) - Very small areas
  • • Square centimeter (cm²) - Small measurements
  • • Square meter (m²) - Standard unit
  • • Hectare (ha) - 10,000 m² for land
  • • Square kilometer (km²) - Large areas

Imperial System

Traditional British measurements

  • • Square inch (in²) - Small areas
  • • Square foot (ft²) - Room measurements
  • • Square yard (yd²) - Fabric and carpeting
  • • Acre - 43,560 ft² for land
  • • Square mile (mi²) - Large territories

Agricultural Units

Specialized farming measurements

  • • Acre - Primary agricultural unit
  • • Hectare - Metric agricultural standard
  • • Square rod - Historical surveying
  • • Section - 640 acres (1 mi²)
  • • Township - 36 sections

Regional Variations

Country-specific measurements

  • • Dunam - Middle Eastern countries
  • • Rai - Thailand land measurement
  • • Bigha - Indian subcontinent
  • • Manzana - Central American countries
  • • Tsubo - Japanese area unit

Frequently Asked Questions

What's the difference between an acre and a hectare?

An acre is 4,047 m² (Imperial system), while a hectare is exactly 10,000 m² (metric system). One hectare equals approximately 2.47 acres.

How do I calculate square footage for irregular shapes?

Break irregular shapes into rectangles, triangles, and circles. Calculate each area separately, then add them together for the total area.

Which area unit should I use for real estate?

Use square feet for indoor spaces, acres for large properties in the US, or square meters and hectares in metric countries. Always check local conventions.

How accurate are these area conversions?

Our conversions use internationally recognized standards and are accurate to 6+ decimal places, suitable for professional surveying and engineering applications.
