Explicație pas cu pas:
1)10 km = ...m = 10 ×1000=10000 m
100hm = 100÷100 =1 m
15 dam = 15 ×10 = 150 m
b) 12 m ...cm =12 × 100 =1200 cm
210m..cm = 210 ÷10 = 21 cm
80 dm...cm =80× 10 = 800 cm
c) 145 dal... l = 145 ×10 = 1450 l
2500 cl ... l = 2500 ÷ 100 = 25 l
2 Kl ... l = 2 × 1000 = 2000 l
d) 17 Kg ... gr =17 × 1000 = 17000 gr
810 dg... gr = 810 ÷ 10 = 81 gr
54 dag...gr = 54 × 10 = 540 gr
