Second line: 200 dm² = 20,000 cm² and 1 a = 100 m²

Quick reference — area conversion table

km² → m² (× 1,000,000)

  • 1 km² = 1,000,000 m²
  • 0.5 km² = 500,000 m²
  • 2 km² = 2,000,000 m²
  • 1 ha = 10,000 m²
  • 1 km² = 100 ha

m² → cm² → mm²

  • 1 m² = 10,000 cm²
  • 1 m² = 1,000,000 mm²
  • 0.5 m² = 5,000 cm²
  • 1 dm² = 100 cm²
  • 100 cm² = 0.01 m²

Imperial / US

  • 1 acre = 4,047 m²
  • 1 sq ft = 0.0929 m²
  • 1 sq mi = 2.59 km²
  • 1 hectare ≈ 2.47 acres
  • 1 m² ≈ 10.76 sq ft

Land units

  • 1 hectare (ha) = 100 a
  • 1 are (a) = 100 m²
  • 1 centiare = 1 m²
  • 1 ha = 0.01 km²
  • 10,000 m² = 1 ha

How to convert hectares to m²?

1 hectare (ha) = 10,000 square meters. To convert ha to m², multiply by 10,000. To convert m² to ha, divide by 10,000. Also: 1 km² = 100 ha = 1,000,000 m² — essential for land measurement, real estate, and agriculture.

ha × 10,000 = m² m² ÷ 10,000 = ha km² × 100 = ha 1 a = 100 m²

Square meters to square feet — US customary

1 square meter = 10.764 square feet. To convert m² to ft², multiply by 10.764. This conversion is frequently used in architecture and interior design. For larger areas: 1 acre ≈ 4,047 m², 1 square mile ≈ 2.59 km².
