1 meter (m) is equal to 1000 milimeters (mm). Therefore, 72 mm is equal to
[tex]72\operatorname{mm}=72\operatorname{mm}\cdot(\frac{1m}{1000\operatorname{mm}})[/tex]which gives
[tex]\begin{gathered} 72\operatorname{mm}=(\frac{72}{1000})m \\ 72\operatorname{mm}=0.072m \end{gathered}[/tex]therefore, 72 milimeters equal to 0.072 meters
