How to convert PSI to kg/cm2??
 

Hmm... havn't actually found how to do it...

With the stock oil pressure gauge (though I really should get another one I guess)



I get (on the stock gauge) about 2.5 at idle, and maybe 4-4.5 at 4500 rpms...
'dis OK??


Math isn't my strong suit

Good to three significant figures:

X kgf / cm^2 = ( Y lbf / in^2 ) * 1 kgf / 2.2 lbf * 1 in^2 / 6.45 cm^2 = Y / 14.2

so 15 psi = 1.05 kgf/cm^2

See also this website for more conversions:

or here:

(Your gauge may be reading incorrectly, or there may be another scale factor involved. Above I have used kgf and lbf for kilogram-force and pound-force. Technically a kilogram is a unit of mass not force.)

Yep, kg is a measure of mass, not force. The Japanese are the only ones who regularly use kg/cm², but kPa or bar are the correct metric units for pressure.

FYI...
1 kg/cm² = 14.2 psi
1 bar = 100 kPa = 14.5 psi
1 atmosphere = 14.7 psi

That's only a little different than what I worked out myself... what messed me up was that you can't just convert cm2 to inches2 as a straight area conversion... since it's pressure, the value will DECREASE as opposed to increasing...
And yes, I always thought it was strange that kilos would be used as a wieght/pressure, when it, by definition, is a MASS measurement, and doesn't change whether you are on earth of the moon!

I don't know... I'm drunk now.
Thanks much!
