About the Pressure Converter
Pressure is the force applied perpendicular to a surface per unit area. The SI unit is the Pascal (Pa). Different industries favour different units: meteorology uses millibars or hectopascals, engineering uses bar or PSI, and medicine uses millimetres of mercury (mmHg / Torr) for blood pressure. Our converter supports 11 units covering the full range from everyday tyre pressure to deep-ocean measurements.
Quick facts
- ›Standard atmospheric pressure is 101,325 Pa = 1.01325 bar = 14.696 PSI
- ›A typical car tyre is inflated to 30–35 PSI (2.1–2.4 bar)
- ›Blood pressure is measured in mmHg — normal is around 120/80 mmHg
- ›The Mariana Trench exerts a pressure of approximately 1,086 bar at its deepest point
