Use the Quick Dial slider to simulate pressure changes, similar to using a regulator valve or pump. The gauge instantly visualizes the PSI value, while the comparison bar at the bottom shows how that pressure relates to standard metric scales (Bar).
The color gradient on the gauge shifts dynamically based on pressure thresholds: Blue for low pressure (Vacuum), Green for standard operating ranges (Tires/Hydraulics), and Red for high-pressure critical zones (Industrial equipment).
The preset buttons allow you to instantly check conversion factors for common scenarios. For example, clicking "Atmosphere" instantly sets the value to 101,325 Pascals, 14.7 PSI, and 1 Bar simultaneously.
