Main Question or Discussion Point

Hi All,

I have a stress strain curve, which have strain(in/in) on x axis and stress in Y axis(Psi).
Here I want to conver the curve to stress(MPa) and strain (mm/mm). I know that Psi can be converted by multiplying the digit by 0.00689475729. But in this case I need to change the strain value? As strain is a unitless quantiy I can use as it is?

Hi shinoy, welcome to PF.

You are correct; strain has no units, so it doesn't need to be converted (equivalently, it can be labeled mm/mm, yard/yard, or anything you like).
