Van \(\text{km}\) naar \(\text{dm}\) is \(4\) stappen, per stap vermenigvuldigen met \(10\text{,}\) dus \(0{,}88\text{ }\text{km}=8\,800\text{ }\text{dm}\text{.}\)

Van \(\text{m}\) naar \(\text{km}\) is \(3\) stappen, per stap delen door \(10\text{,}\) dus \(12\text{ }\text{m}=0{,}012\text{ }\text{km}\text{.}\)

\(2{,}7\text{ }\text{km}^2=27\,000\text{ }\text{dam}^2=27\,000\text{ }\text{are}\)

\(5{,}5\text{ }\text{m}^2=0{,}00055\text{ }\text{hm}^2=0{,}00055\text{ }\text{ha}\)

\(9{,}1\text{ }\text{dL}=0{,}91\text{ }\text{L}=0{,}91\text{ }\text{dm}^3\)
