How do I get velocity per second w/Physics?

Greetings! I am currently using :

int((P_hull.Physics.VelocityX^2 + P_hull.Physics.VelocityY^2)^0.5)

to get velocity of my car every tick. What I really need is a way to get car's velocity per second, in Pixel per second, lets say. How do I pull this off?

Thanks in advance.

VelocityX and VelocityY are allready in units pixels/second.

IF you use the action 'Set stepping mode' to 'Framerate independent'

And if not, and that is the default setting, it using a fixed fake dt to calculate its speeds.

I think that is 1/60.

So then the correction is (Velocity /60) / dt

Normally the relation between 'pixels/tick' and 'pixels/second' is ...

'pixels/tick' = 'pixels/second' * dt
