converting chamber pressures

Does kPsi not mean 1000 pounds per square inch?

If so then 64.5 kPsi would also be 64,500 psi.

Multiply by 1000?

Simply put 1kPsi = 1 X 10*3 psi

Kpsi is a very confusing combination of imperial and metric, or it certainly appears to be. My guess would be that 64Kpsi would be 64000 psi, but, I'd ask the author for clarification. That's your face you are working with, not his.

:confused: I'd be guessing typo here. Kps, or kilopascals is a pressure measurement in metric, and psi, one in imperial, but KPSI? someone goofed thats like pressure by the sqaure centimeter over and inch square? no sense at all. I think someone is used to writing psi and got carried away at the end of Kps.
 
kPsi=psi

how do you convert kPsi to lbs. per sq. in. 64.5kPsi=? psi.:dancingbanana:

this is the way it is written up in the pressure column in the accurate powder loading data for the 270wsm,thanks:dancingbanana:
 
I agree kPsi is not a proper use of any term. When people want to abbreviate 1000 psi the conventional usage is to replace the 'p' with a 'k', hence 1000 psi = 1 ksi. It is very commonly seen in strength of materials statements, such as the modulus of elasticity value in this summary:

The poor form notwithstanding, I think it is clear that the term is meant to mean thousands of psi, so 64.5 mystery units = 64,500psi.
