Common mistakes

  • An acre is about 4,047 m², which is roughly 0.405 hectares, not the other way around. One hectare holds about 2.47 acres. Buying property abroad: multiply acres by 0.405 to get hectares.
  • For areas the length factor must be squared, using it directly is the classic trap. 1 km is 1,000 m, but 1 km² is 1,000,000 m², and 1 m² is 10,000 cm². The rule: convert the length unit, then square the factor.
