Common mistakes

• ✕Squaring the linear factor only once — 1 m = 3.281 ft, but 1 m² = 10.764 ft² (factor squared).
• ✕Confusing acres with hectares (1 ha ≈ 2.471 acres).
• ✕The US survey acre differs slightly from the international acre. Land titles recorded using the US survey foot give an acre of about 4046.87261 m² — roughly 0.0004% larger than the international acre of 4046.8564224 m². On a single residential plot this is a few square centimetres. On a large ranch it can be several square metres, which is why legal descriptions state which foot was used.
