The Swedish tunnland, the area one barrel of seed could sow, is about 4,936 m², roughly half a hectare. Older property records are often misread as full hectares. Working rule: two tunnland ≈ one hectare.
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.
