Fyi standard temp and pressure at is 14 psi, so 10 is actually a slight vacuum. Or 10 over current is still not very much. Usually not enough to even explode. people can blow up to about 20psi, eg 6 psi over stp (otherwise we couldn't breathe). So it'd be more like a birthday baloon that flubbered around for 4 seconds and then went flat.

Interesting. So if my bike tire is at 10 lbs, is that 10 above atmosphere or just 10psi? I think a balloon flubbering arround for 4 seconds then going flat at the office would still be considered a scene. In fact I think your depiction is perfect. Ha.

Bike tires are typically inflated to a psi (lbs per square inch). A bike tire is a bad example in this context because most are filled pretty high (80-130psi, mine are 90psi). The average car tire is 30-40psi.

I run my dirt bikes trials tire at about 10 psi rear, and 14 front. Mountain bike tubeless 14-25 psi. So I guess my question was, is a guage measurement above atmospheric pressure? The answer is yes. [0] "Gauge Pressure: The pressure of a system above atmospheric pressure."

Of all the times I've ever heard a pressure figure mentioned in casual conversation, I cannot recall a single time where the person was referring to absolute pressure rather than gauge pressure.

In fact, if I were at a party and I mentioned something about "10 psi", only to have someone correct me by saying "actually that's a slight vacuum...", I would assume they were trying to be mean.

okay 10 atm then
