For a simulation, the scale/unit of physics properties is not fixed.
e.g. the screen width can represent 1cm or 1km. It is depends on how you choose the unit.

I did add several sliders for user to adjust related parameters.

Could you provide a simple drawing about the ruler? and what is the role for the ruler?
