I am looking into crossover fantasy - the protagonist coming from our world and moving into another. While I want to describe time and distance the way the protagonist understands them - hours, meters, etc I find this jars against the world I am building, which is looking at time and distance in a more archaic manner. Are there some suggestions how to best describe these? And the difference between the protagonists POV vs just describing it generally (not from a POV of anyone.) Does talking about 'what seemed like hours passing' from the POV seem strange when the people around her do not go to that granular detail e.g. see it as the passage of the sun's arc as a good gauge of time etc. What about if the world measures distance by steps (or something along those lines.) but the protagonists sees them as meters?
