1 bar is "slightly less than the current average atmospheric pressure on Earth at sea level." It's a unit that helps people conceptualize the amount of pressure because it's close to the atmospheric pressure we live in. It doesn't help that a bar is exactly 100,000 Pascal. It slightly helps that it's 14.50377 psi.
LPM is liters per minute. In some places it's litres per minute.
GPM is gallons per minute.
Did I not explain that clearly enough?
1 bar, or 2 ba, can be converted to PSI, just as LPM can be converted to GPM.
Isn't that what I posted? Did YOU not understand?
