Subsection 2.1.2 Conversion Factors
The table below contains a large number of values that can be used to make unit-factors.
For example, the first entry says:
\begin{equation*}
\mathrm{acre} \qquad 43560 \qquad \ft{}^2
\end{equation*}
The associated unit factors are
\begin{equation*}
1 = \left[\frac{ \mathrm{1 \ acre}}{\ft{43560}^2}\right] \quad \text{ or } \quad 1 = \left[\frac{\ft{43560}^2}{\mathrm{1\ acre}}\right]\text{.}
\end{equation*}
Multiplying a quantity by one of these factors will convert acres to square feet, or vice-versa.
