1 Pascal = 1 Newton / Meter^2
1 Bar = 14.7PSI = 101.3 kPa
(9.81 N/ 1 CM^2) * (10,000 CM^2/1 M^2) = 98 100 N/M^2 = 98.1 kPa
So, 600 * 98.1 kPa/101.3 = 581 Bar = 8,540 PSI.
61x injector pop pressure is closer to 1500 PSI, isn't it?
If anything, it would be hard to be precise with this gage. Pop will occur at about 1/6th full scale deflection. When you can, it's better to spec a gage more closely matched with the test condition, say 2-3 kSI

My error.
I read it as 8534.006 PSI
Depending upon application; The OM61x injectors pop from 1600 - 2180 PSI.
The high end is generally commercial/marine/generator application..
I prefer a 4000 or 6000 PSI gauge, as the reading is more accurate..
