5000 m = 50 hm = 500 dam = 1 km

5 000 m = ( 5000 : 100 ) hm = 50 hm,     m < hm de 100 de ori

5 000 m = (5000 : 10 ) dam = 500 dam,  m < dam de 10 ori

800 dam = 8 000 m = 8 km = 80 000 dm

800 dam = ( 800 × 10 ) m = 8 000 m,           dam > m de 10 ori

800 dam = ( 800 : 10 ) hm = 80 hm,             dam < hm de 10 ori

800 dam = ( 800 : 100) km = 8 km,               dam < km de 100 de ori

800 dam = ( 800 × 100 ) dm = 80 000 dm,   dam > dm de 100 de ori

780 000 m = 7 800 000 dm = 78 000 dam = 780 km

780 000 m = ( 780 000 × 10 ) dm = 7 800 000 dm,   m > dm de 10 ori

780 000 m = ( 780 000 : 10 ) dam = 78 000 dam,    m < dam  de 10 ori

780 000 m = ( 780 000 : 1 000 ) km = 780 km ,     m < km de 1 000 de ori

780 000 m = ( 780 000 : 100) hm = 7 800 hm,     m < hm de 100 de ori

12 hm = 1 200 m = 120 dam = 12 000 dm

12 hm = ( 12 × 100 ) m = 1 200 m,          hm > m de 100 de ori

12 hm = ( 12 × 10 ) dam = 120 dam         hm > dam de 10 ori

12 hm = ( 12 × 1000 ) dm = 12 000 dm,  hm > dm de 1 000 de ori
