Common Area Conversions

  • 1 square meter = 10.7639104 square feet
  • 1 acre = 4046.8564224 square meters
  • 1 hectare = 10,000 square meters
  • 1 square mile = 2.58998811 square kilometers
  • 1 square foot = 0.09290304 square meters (exact)
  • 1 square inch = 6.4516 square centimeters (exact)

Area Units and Standards

Area units are derived from length units squared:

  • Square meter (m²): SI derived unit from the meter
  • Hectare (ha): 10,000 square meters, used for land areas
  • Acre: Traditional unit used for land measurement
  • Square foot (ft²): Common unit in construction

Understanding Area Measurements

Area measures the extent of a two-dimensional surface. It's calculated by multiplying length by width for rectangular shapes, with more complex formulas for other geometries. Area measurements are critical in fields ranging from construction and real estate to agriculture, mapping, and scientific research.

Precision: 15 decimal places
Standard: ISO 80000-3:2019

Area Units in Different Systems

Metric Area Units

The metric system uses the square meter as its base unit:

  • Square kilometer (km²): 1,000,000 square meters
  • Hectare (ha): 10,000 square meters
  • Square meter (m²): Base unit
  • Square decimeter (dm²): 0.01 square meters
  • Square centimeter (cm²): 0.0001 square meters
  • Square millimeter (mm²): 0.000001 square meters

Imperial/US Area Units

Imperial and US customary units for area include:

  • Square mile: 640 acres
  • Acre: 4,840 square yards
  • Square yard: 9 square feet
  • Square foot: 144 square inches
  • Square inch: Base unit for small areas

Land Measurement Units

Specialized units used for land measurement:

  • Hectare: Used in most countries for agricultural land
  • Acre: Traditional Anglo-American land unit
  • Rai: Used in Thailand (1 rai = 1,600 m²)
  • Mou: Used in China (1 mou ≈ 666.7 m²)
  • Township: 36 square miles (US land surveys)

Converting Between Area Units

When converting between area units, remember that you must square the conversion factor used for linear measurements. For example, since 1 meter = 3.28084 feet, 1 square meter = 3.28084² = 10.7639 square feet, not simply 3.28084 square feet.
