Pumping gauge in PSI instead of HG

I wanted to post this in the Pumpers forum, but it won’t let me

I recently got a pump without a gauge ( I know a big mistake ) and now I’m going to buy a gauge, but all the gauges I see are in PSI instead of HG so all this talk about not going above 5 HG, well what is that in PSI?

I moved it for you.

To convert PSI to inHG, multiply it by 2.036.

To convert inHG to PSI, divide it by 2.036. So 5.0 inHg would be about 2.5 PSI.

Perhaps it is better to buy a pump with a gauge. I made the mistake of buying a pump without a gauge and bought a gauge separately. But to get the pressure to work accurately I would have to drilled a hole in the tube, thus weakening it. So I bought a pump and gauge combined and solved the problem, using the original tube. Most people here work in Hg, 5 seems to be about the safe limit although I do go a little higher maybe 6 or 7 occasionally. Good Luck.

You can buy one from McMaster-Carr for under $10…Check them out and get the HG.

Ok thanks lampwick.. I will now be pumping at or about 2 psi.. Thanks soo much

Do any local stores (walmart, etc.) sell pressure gauges with lower numbers or vacuum gauges?
