Psi/bar conversion
 

Do any of you know how to convert negative bar into inches of vacuum? I bought a bar boost gauge accidentally and I was curious how much vacuum I am actually pulling at idle. The gauge reads -.8 bar. I found a bunch of converters online, but they are are for positive pressure. I.E= 14.7 psi is 1 bar, etc.....

Thanks,
Rob

.8 bar * 29.54 to convert to in. HG = 23.632 in. HG

um...you would think that negative values are the same as positive ones, but i guess thats applies to people with common sense.

Thanks. :) I thought i'd ask. I guess that is some pretty decent vacuum at idle.
