Subsection 1.3.2 Conversion of Units
The unit can be converted from one system of units to another or within the system of units itself.
Example 1.3.3.
Convert 50 \(km/h\) into \(m/s\)
Convert 50 \(mile/h\) into \(m/s\)
Convert 2 \(m^2\) into \(cm^2\)
Solution.
\begin{equation*}
\frac{50km}{hour}\cdot \frac{1000m}{1km}\cdot \frac{1hour}{60\times 60 s}=13.89m/s
\end{equation*}
\begin{equation*}
\frac{50mile}{hour}\cdot \frac{1609m}{1mile}\cdot \frac{1hour}{60\times 60 s}=22.35m/s
\end{equation*}
\begin{equation*}
2m^2 = 2\cdot\left(\frac{100cm}{1m}\right)^2=20000 cm^2
\end{equation*}
