<h3>Units conversion:</h3><h3 />

In science, we use units conversion to represent measurements in different types of units depending on a specific requirement. To do so, we use conversion factors based on equivalence statements, relating the required unit with the given one.

In this case, the equivalence statement between inches and centimeters is 2.54 cm = 1 in and we can use it to get the answer as shown below:

$17.2in*\frac{2.54cm}{1in} \\\\=43.7 cm$
