Conversion of Pressure (Bar) to kg x 1000 or Ton
Conversion of Pressure (Bar) to kg x 1000 or Ton
(OP)
I have a pressure gauge on a unit, and it reads in two scales: kg x 1000, and Ton.
When pressure was applied to the gauge, the readings were recorded (see below).
Guage (Tons) Standard (bar) Guage (kgx1000) Standard (bar)
1 12.25 1 13.76
2 29.05 2 31
3 46.5 3 45.8
4 64.2 4 64.2
5 82 5 82
I do not know, and have not been able to find out, how to make the correlation between Ton and Bar, or Kg x 1000 and Bar.
Any help would be much appreciated.

Tons is a measure of weight, not pressure.
kg x 1000 is a measure of mass, not pressure.
bar is a measure of pressure.
Pressure is force per area. Tons per square inch, perhaps, Newtons per square meter, or Pascals.
Good on ya,

The funniest thing about kgf/cm^2 is that it is such a worthless measure. According to Katmar's excellent Uconeer program 1 bar = 0.981 kgf/cm^2 (something quite memorable about the digit-order in that number) so there is zero benefit to bastardizing SI further for this silly unit.
I would guess that the messed-up table in the OP is just sloppy handling of parallax issues.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

Pressure = force/area. The area the force is applied over is the area of the cylinder ram.
So force/area*area = force

I have attached a picture of the gauge and the unit it is part of.

This is the complete unit that the gauge is part of.
There is a lever on the side of the unit that is "pumped" manually (like an old water pump), bringing the cylindrical bar down onto a metal part.
The gauge measures the applied force (or mass) to the part. The gauge is acting on pressure, so it made sense to me to apply pressure from a reference standard an find the correlation between the applied pressure and the mass readout.
This is all I'm looking to do. I just need to know how to get from my ref. std. pressure reading (in Bar) to the Ton / kg x 1000 reading on the gauge.

I will have to try and take it from here I think, doubt there is much else anyone can do for me.
