How to convert Newton to PSI

[spanishfly25]

does anyone know how to make the conversion from pounds to PSI in a Carver press or even better from Newton to PSI. the press has a broken pressure gauge and I need to replace it and calibrated.

I would say that is dependent on the area of the ram.

Have you tried the mfg.?

thanks the RAM is 3.29  PSI times Ram = pounds

[OlDave]

pounds force times 4.448222 = newtons

Try the Versaverter from pawprint.net.

It does not have a PSI to Newtons Conversion.. But I does have a lot of conversions I think are handy..

Making the assumption that the ram is round you first have to find the area of the ram
R_area=Pi(r²)
Knowing the area of the ram you can complete the formula  Pressure=Force/area
Force = Mass* accelleration of gravity
So now you can convert the mass, area and use the correct acc of gravity convert accurately between PSI & Newtons. 
Since the pressure in the system remains constant changing the area of the output piston changes the force the system is generating at the output. So with that said we go back to P=F₂ / Area₂ which can be changed to F₂=P*Area₂ ...sooooo since the pressure in the system will remain the same you can find the second force by completing
F₁=P/Area₁

Hope this helps!

Oh and just because I had to explain this to someone the other day
grams are mass
pounds are force
This is really important to remember when working with pressure systems....

I always use the site http://www.onlineconversion.com/ whenever I have to convert something.  I checked and they do have a Force conversion of Newtons to Pounds of Force and others too numerous to mention.  Didn't see a direct conversion to psi but it may be in there somewhere.  John Treekiller
