Conversion

[bikswahla]

hey guys

Can some one help me how can we convert PSI into lbf. I am working on one testing fixture whose gauge reads 40psi, I want to convert to lbf, coz the specs in the test is 300lbf. Is some know how we can convert it.

Well PSI is 1 lbf per square foot. So your test should involve an area the pressure is acting on. You need to multiply the area in inch^2 by the 40psi to get your lbf.

Say for example you have a 40psi force acting on a 2" rod of a cylinder. The area of the face of the rod is 3.14 in^2.

Therefore:

(40lbf/in^2)*(3.14 in^2)
= 125.7 lbf

Hope this helps

"Well PSI is 1 lbf per square"... inch.

What everyone is saying is multiply psi * surface area to get to lbf. Applying 40 psi to an area that is 7.5 in^2 would equal 300 lbf.

Hi guys

thanks a lot for your help, I think I was calculating right but was not confident. Now I am

Yeah sorry, I meant inch. Need to remember to read over what I typed.
