1 E+4 m²

From Wikipedia, the free encyclopedia

To help compare orders of magnitude of different areas, areas between 1 hectare (10,000 m²) and 10 hectares (0.1 km²) are listed below.

• Areas smaller than 1 hectare
• 1 hectare is equal to:
  • 1 E+4 m² or 10,000 m²
  • 100 ares
  • 108,000 square feet
  • 2.5 acres
• 1.2126 hectares -- Plaza Mayor of Madrid^[1]
• 1.35 hectares -- Piazza del Popolo, Rome^[1]
• 2.3 hectares -- Red Square, Moscow^[1]
• 2.68 hectares—area of the RMS Queen Mary 2's passenger decks
• 3.2 hectares -- Palace of Westminster
• 3.76 hectares -- Castelmoron-d'Albret, the smallest commune of France
• 4 hectares -- Fort Severn, the first campus of the US Naval Academy
• 4.5 hectares -- Wenceslas Square, Prague^[1]
• 5.5 hectares—base of the Great Pyramid of Giza
• 5.7 hectares -- Plaza de la Constitución, Mexico City
• 8.4 hectares -- Place de la Concorde, Paris
• Areas larger than 10 hectares
