Hi, I note in another thread that in order to convert PSI to Kn the following is suggested.

PSI means pounds per square inch, which is a measure of pressure:

Kilonewtons is a measure of force.

So if you want to convert pressure to force, you need to know the area over which the pressure is acting. An example would be if you are applying a pressure of 100 PSI over an area of 10 square inches, then you would get:

100 PSI * 10 square inches = 1000 lbs of force

Then you can convert the lbf to kN:

I am trying to ascertain if I can compress copper using a 35kN tool and achieve 10,000 PSI.

The area (inches) of the connector that I need to compress is 0.53 x 0.69
(other data that may or may not be relevant is the height of this connector. It is 0.53 and will be compressed down to a height of 0.25. The CMA of material within the connector to be compressed can vary from 10,000 - 50,000)

Can you please advise if I am working this out correctly.

Area of connector 0.53 x 0.69 = 0.3657 square inches.

Using a nominal figure of 10,000 PSI x 0.3657 = 3657 lbs of force
3657lbs = 16.267kN

Therefor I easily achieve my required PSI over this area using the 35kN tool?
In fact it seems that 20,000 PSI is possible with this tool over that area?
