100 cm=.......km,10 km=........m,5dam =............cm,20 mm=..........km,4 m=..........mm.isi dan penjelasanya

100 cm= (100 : 100.000 km) = 10^-3 km ( 10 pangkat -3)
10km = (10 x 1000 m) = 10^4 m (10 pangkat 4)
5 dam = (5 x 1000 cm) = 5 x 10^3 cm atau 5000 cm
20 mm = (20 : 1000.000) = 2 x 10^-5 km
4 m = (4 x 1000) = 4 x 10^3 mm atau 4000 mm
