Feng and Huang in 2016 defined a new notion called weighted topological entropy (pressure) and obtained the corresponding variational principle for compact dynamical systems. In this paper, it was our hope to carry out a further study from the following three aspects:

(1) Inspired from the well-known classical entropy theory, we define various weighted topological (measure-theoretic) entropies and investigate their relationships.

(2) The classical entropy formula of subsets and their transformations by factor maps is generalized to the weighted version.

(3) A formula which comes from the Brin-Katok theorem of weighted conditional entropy is established.

Keywords: Weighted topological entropies, weighted measure-theoretic entropies, weighted conditional entropies, factor maps, entropy formulas.
