How to use

1. Key in the value in the input box (e.g.)100） 2. Select the original unit (e.g.)psi） 3. The system automatically outputs the conversion results of other units (kPa/bar/atm, etc.).

Application Scenario

- Conversion of automotive tire pressure (psi ↔ bar) - Calibration of industrial equipment pressure parameters - Standardization of laboratory data - Adjustment of meteorological barometric pressure reporting units Conversion benchmarks:
All calculations are based on international measurement standards, including:
• 1 bar = 100 kPa = 14.5038 psi
• 1 atm = 101.325 kPa = 1.01325 bar
• 1 mmHg = 133.322 Pa Tool data is calibrated and updated daily to ensure accurate and reliable calculations.
