Van \(\text{dm}\) naar \(\text{mm}\) is \(2\) stappen, per stap vermenigvuldigen met \(10 \text{,}\) dus \(9{,}8 \text{ } \text{dm} = 980 \text{ } \text{mm} \text{.}\)

Van \(\text{cm}\) naar \(\text{hm}\) is \(4\) stappen, per stap delen door \(10 \text{,}\) dus \(720 \text{ } \text{cm} = 0{,}072 \text{ } \text{hm} \text{.}\)

\(5{,}1 \text{ } \text{hm}^{2} = 510 \text{ } \text{dam}^{2} = 510 \text{ } \text{are}\)

\(5{,}2 \text{ } \text{dam}^{2} = 0{,}052 \text{ } \text{hm}^{2} = 0{,}052 \text{ } \text{ha}\)

\(8{,}3 \text{ } \text{cL} = 0{,}083 \text{ } \text{L} = 0{,}083 \text{ } \text{dm}^{3}\)
