1m²  –  1dm²  –  1cm²  –  1mm²

1m² = 100 dm²
1dm² = 100 cm²
1cm² = 100 mm²

1m² = 10 000 cm²      1 square metre = 10 000 square centimetres 
1ha = 10 000 m²        1 hectare = 10 000 square metres   
1km² = 100ha            1 square kilometre = 100 hectares   
1a =100 m²                1 are = 100 square metre
