Numbers are numbers. We cant really relate without any experience. Its very much like trying to tell someone the temperate in Celsius to someone who grew up with the Fahrenheit scale.

I imagine virtual reality glasses could be used. Like those VR ads where you are a gamer in a mix between virtual reality addons and a physical room.
Then in a museum we could create environments where you are virtually transported in time.
