Convert pressure readings accurately between metric and imperial systems. Essential for engineering, meteorology, and automotive work.

1. Enter Value

Type the pressure value.

2. Select Units

• From: E.g., PSI.
• To: E.g., Bar.

3. Result

• PSI to Bar: Common for tire pressure. 1 Bar ≈ 14.5 PSI.
• Atm to Pascal: Standard scientific conversion. 1 atm = 101,325 Pa.
• Torr to mmHg: Used in medicine and vacuum measurements. 1 Torr ≈ 1 mmHg.

We support a vast range of units including:

• SI Units: Pascal (Pa), Kilopascal (kPa), Megapascal (MPa).
• Imperial: PSI (Pounds per Square Inch), KSI.
• Atmospheric: Standard Atmosphere (atm), Technical Atmosphere (at).
• Meteorological: Bar, Millibar (mbar), Hectopascal (hPa).
• Liquid Column: mmHg, inHg, cmH2O (for varying temperatures).

• Precision: Calculations are performed with high precision.
• Wide Range: From micro-pressures (micropascal) to massive geological pressures (Gigapascal).
