Instantly convert between Bar and PSI for your espresso machine.
Gauge range: 0 - 15 Bar
To convert Bar to PSI, multiply by 14.5038.
Example: 9 Bar × 14.5038 = 130.53 PSI.
What is the standard pressure? Most professional and home espresso machines are calibrated to pull shots at 9 Bar of pressure.
Why does it matter? Incorrect pressure can affect extraction quality, crema consistency, and the overall flavor profile of your shot. Lower pressures (6 Bar) are often used in "turbo shots" or lever machines, while higher pressures (12 Bar) were common in older machines.
Conversion Note: 1 Bar is approximately equal to 1 atmosphere of pressure at sea level.
