What is pressure?
Pressure is the force applied per unit area and is commonly measured in units such as Pascals (Pa), bars, or pounds per square inch (psi).

A pressure converter allows users to convert between different pressure units by:
- Selecting the Input Unit—Choose the current pressure unit.
- Entering the Value—Input the numerical pressure value.
- Choosing the Output Unit—Select the unit to convert into.
- Getting Instant Results—The tool calculates and displays the equivalent pressure value.

Common Applications of Pressure Conversions
- Tire Pressure Checks: Convert psi to bar or kPa.
- Weather Forecasting: Convert atmospheric pressure readings.
- Industrial Machinery: Ensure correct calibration of equipment.
How to Convert Pressure Manually?
For manual calculations, use the following formulas:
- psi to kPa: Multiply by 6.89476
- bar to atm: Multiply by 0.98692
- mmHg to Pascals: Multiply by 133.322
Example:
Convert 30 psi to kPa:
30×6.89476=206.8430 \times 6.89476 = 206.8430×6.89476=206.84 kPa
