tire pressure gauge
On the tip of the moving part that shows the pressure
number, there are (3) different letters. psi, kpa and bar.
What does bar indicate. If it is for barometric pressure,
how does that relate to 32 psi?
The standard atmospheric pressure is 1013.4 mb or 29.92 in hg,
so why include bar on a tire gauge. How is it important to me?
