On retrouve deux colonnes pour chaque unité car ce sont des unités au carré :

5,46 m^2 = ... dm^2 = 546 dm^2

97 km^2 = ... hm^2 = 9700 hm^2

0,33 cm^2 = ... mm^2 = 33 mm^2

948 cm^2 = ... dm^2 = 9,48 dm^2

400 dam^2 = ... hm^2 = 4 hm^2

15 000 m^2 = ... km^2 = 0,015 km^2

km^2 | hm^2 | dam^2 | m^2 | dm^2| cm^2|mm^2
