OK,

Why do Boost gauges often come in "BAR"? Is there a reasion why everyone likes bar and not psi?

sorry I'm just not educated in this area...

 

most of them come from japan and they dont use psi there

 

So whats a quick way to convert?
If they do come in PSI why do people still get Bar?

 

The entire world (except the US) uses the metric system, so there would be no pounds per square inch.....its ok for everyone else but you gotta do some converting when in the good ole US of A!

 

1 bar is equal to aproximately slightly more than 14 PSI...Have to find out the exactly coversion rate...

 

14.5psi = 1bar

 

so why do people still get the BAR and not PSI?
I'm about to get a boost Gauge and I'm deciding on the HKS AC gauges but they are in bar...

 

the reason is becuase most companys who make good gauges are from Japan. if you buy autometer and other USA gauges you will get PSI. i think the only JDM company who has PSI gauges right now is DEFI and they are expensive and hard to come by. just get the BAR gauges, you will get used to it very soon and you will have very nice gauges

 

yes i like the HKS AC blitz ones... I guess it will take getting used to.... feel free to still comment thanks blonde

 

Bar is metric units, psi is engilsh units. Trust me, as I am an engineer, english units suck, especially when dealing with pressure in thermodynamics and fluid mechanics. The metric system is much easier to use. We are the only country that doesnt use it.

 

i thought it was 14.7 psi to every bar of atmospheric pressure?

 

14.5 is correct

Here's a page that auto converts for ya:

kg/cm2(bars) to PSI x 14.223
PSI to kg/cm2(bars) x .070

 

metric system is better

 

hell yea metric is easier... especially with tools
