How do I convert 41in^2 to cm^2?

Question

mathmale · Answer

What is the relevant conversion factor?  I have this impressed in memory:  1 inch = 2.54 cm.

You could start with 41 in^2,
Enclose that "in" inside partentheses:  41 (in)^2, and then replace "in" with "2.54 cm".

Willing to try that?

$$41inch ^{2}=41*2.54*2.54 cm ^{2}=?$$

$\large \begin{array}{llll}
in&cm\
\hline\
1&2.54\
1in^2& 2.54^2\
\hline\
41in^2&41( 2.54)^2\implies 41\cdot 2.54^2
\end{array}$

JD:  Apprreciate your acting on my suggestion.  My only additional suggestion is that your final result should have units of measurement as an integral part.
