Let \(T\) be a piecewise monotonic expanding map on a union \(X\) of finite intervals and set \(R(T)= \bigcap_{n\geq 0} T^{-n}X\). Assuming that \(T'\) is piecewise Hölder and that \(T\) satisfies the Misiurewicz condition, it is shown that the capacity and the Hausdorff dimension of \(R(T)\) coincide (Theorem 2). Moreover, the same result holds for the capacity and Hausdorff dimension of an ergodic invariant probability measure (Theorem 3). Related results appeared by F. Hofbauer and P. Raith [Can. Math. Bull. 35, No. 1, 84-98 (1992; Zbl 0770.28009)] and P. Raith [Stud. Math. 94, No. 1, 17-33 (1989; Zbl 0687.58013)].
