Unit conversion:1m2 (1m2) =100dm? (100 square decimeter) = 10000cm? ( 10000 cm2)= 1000000mm？ (1000000 mm2) = 0.0001hectare =0.00000 1km? .
(0.000001km2) = 0.01hectare = 0.00044 1054 acre = 0.00 1 square mile =10+038.
Unit conversion is to convert square meters into square decimeters, square centimeters and square millimeters, and then square the carry between them with units. For example,1m =10dm; 1㎡= 10dm× 10dm = 100dm？ . The rest can be converted by this conversion method.
Unit conversion is the calculation of area unit conversion.
