  In Cogdell et al., \it LMS Lecture Notes Series \bf 459, \rm 393--427 (2020),
\rm the authors proved an analogue of Kronecker's limit formula associated to
any divisor $\mathcal D$ which is smooth in codimension one on any smooth
K\"ahler manifold $X$. In the present article, we apply the aforementioned
Kronecker limit formula in the case when $X$ is complex projective space
$\CC\PP^n$ for $n \geq 2$ and $\mathcal D$ is a hyperplane, meaning the divisor
of a linear form $P_D({z})$ for ${z} = (\mathcal{Z}_{j}) \in \CC\PP^n$. Our
main result is an explicit evaluation of the Mahler measure of $P_{D}$ as a
convergent series whose each term is given in terms of rational numbers,
multinomial coefficients, and the $L^{2}$-norm of the vector of coefficients of
$P_{D}$.
