In my car sim I am doing my calculations in Standard Units, except for the distance which is in pixels. Is this still correct (my guess is no) or should I use Meters ?
If I should use meters what is the best way to go about it? should I just pick a scale 10px = 1m or is there a better way to do this ?
thanks in advance.
Some additional info: I'm using Unity3D and using its physics engine.
