Sorry to say that just putting decals on a meter won't allow U to calibrate meter.U have to change out main spring.Having rebuilt over 100 hundred of these metric units over the last 14 years,I have not been able to calibrate kilopascals to psi.without changing spring.1 kilopascal = 0.1450377 psi There is 11 coils in metric spring and 14 in a psi spring.It would be OK for show but not using.Regards Doug
