I work in a hotel and ride elevators upwards of 50 times a day. Never once has the bottom of the elevator been even a fraction of an inch above or below the floor where the elevator begins. Assuming there is a minimal amount of slippage in the cabling, how do the elevators move the exact same distance every single time? Is there some sort of cable/feet math going on where each floor is x amount of motor turns?

You are overthinking the problem, when you tell an elevator to go up and down it’s not measuring cable length, there is simply a sensor at each floor. It only needs to know how many sensors up or down from its current position it needs to go
