Pressure experienced by a diver at 10 meters (33 feet) underwater.
A high-vacuum environment used in scientific experiments.
| Unit | Equivalent Value |
|---|---|
| 1 Pascal (Pa) | 1 N/m² |
| 1 Kilopascal (kPa) | 1,000 Pa |
| 1 Bar | 100,000 Pa |
| 1 Atmosphere (atm) | 101,325 Pa |
| 1 PSI (lb/in²) | 6,894.76 Pa |
| 1 Torr (mmHg) | 133.322 Pa |
How to use: Enter a numeric value, choose the source and target units, then click Convert.
Note: 1 Pascal (Pa) is defined as one Newton per square meter (N/m²). The Bar is a non-SI unit of pressure, defined as exactly 100,000 Pa.
