In English, we can make reference to extent with "how." Translating “How (much)” in non-numeric situations deals with a similar, but not identical question. Note that it focuses on questions and I would like to focus on statements. Also note that most of the answers there revolve around qué tan, which is not used in Spain, and I am looking for forms familiar in Spain.
An example of a sentence that I would have difficulty translating to Spanish is
Last night showed how agreeable his personality is.
In Spanish questions, we can use forms like:
¿Qué/Cuánta valor tienen estas películas?
¿Hasta qué punto son valiosas estas películas?
