Core features

- Instant Calculation： Input any unit value and display the conversion result in real time. Comprehensive coverage： Support international standard units and imperial units conversion High precision： Retains 6 decimal places for precise calculations - Responsive design： Compatible with computers, mobile phones, tablets and other devices

How to use

1. Type 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 tyre pressure (psi ↔ bar) - Calibration of pressure parameters in industrial equipment - Standardisation of laboratory data - Adjustment of reporting units for meteorological barometric pressures. 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.
