How high is the Acropolis?

Excuse me, could you please clarify for me how tall the Acropolis actually is? I've heard various estimates and I'm trying to get a more definitive answer. Is it measured from the base of the rock to the top of the Parthenon, or is there another method used to determine its height? I'm quite interested in the specifics and I'd appreciate it if you could provide me with a clear and concise response. Thank you in advance for your assistance.
