Step 1:
: Write down the conversion factor between meters (since 120 mm is a length given in millimeters) and inches.

1~\text{m} = 39.37~\text{in}
The conversion factor is:

Step 2:
: Since there are 1000 millimeters in a meter, we can rewrite the conversion factor in terms of millimeters:

1~\text{mm} = \frac{39.37~\text{in}}{1000~\text{mm}}

Step 3:
: Now, multiply the number of millimeters by the conversion factor to get the length in inches:

120~\text{mm} \times \frac{39.37~\text{in}}{1000~\text{mm}} &= 4.724~\text{in}
\begin{align*} \end{align*}

Final Answer

120 mm is equal to 4.724 inches.
