Pressure Converter
Easily convert pressure units with our pressure converter. Enter a value to instantly switch between pascals, bar, psi, atmospheres, and more for accurate results.
What is Pressure?
Pressure is defined as the force applied per unit area. It is a fundamental concept in physics, engineering, and meteorology. The SI unit of pressure is the Pascal (Pa).
How to Use a Pressure Calculator
To use a pressure calculator:
- Enter the pressure value you want to convert
- Select the input unit (e.g., PSI, Pa, atm)
- Select the target unit (e.g., bar, kPa, mmHg)
- The calculator will instantly display the converted value
Common Units of Pressure
Pressure can be measured in a variety of units:
- Pascal (Pa)
- Bar (bar)
- Kilopascal (kPa)
- Pounds per square inch (PSI)
- Atmosphere (atm)
- Millimeters of mercury (mmHg)
Applications of Pressure
Pressure calculations are useful in many fields:
- Engineering, to design vessels, pipelines, and machinery
- Meteorology, to study atmospheric pressure and weather patterns
- Physics experiments and research
- Hydraulics and fluid mechanics for system design
Limitations of Pressure Calculators
Keep in mind the following limitations:
- Accuracy depends on correct input values and units
- Some calculators may not handle very large or very small pressures
- Does not account for dynamic factors like fluctuating pressure in real systems

Example
Pressure Converter
A pressure converter allows you to convert between different units of pressure, such as pascals (Pa), atmospheres (atm), bars, millimeters of mercury (mmHg), and pounds per square inch (psi).
Common conversions:
1 atm = 101,325 Pa
1 bar = 100,000 Pa
1 psi = 6894.76 Pa
1 mmHg = 133.322 Pa
Real-Life Example
A car tire is inflated to a pressure of 35 psi, and you want to know what this is in other pressure units:
- Tire pressure = 35 psi
- Convert to pascals: 35 × 6894.76 = 240,314.6 Pa
- Convert to bars: 240,314.6 ÷ 100,000 = 2.40 bars
- Convert to mmHg: 240,314.6 ÷ 133.322 = 1,802.4 mmHg
Key Insight
Pressure conversions are useful in many fields, such as meteorology, engineering, and automotive industries. For example, a tire pressure of 35 psi is equivalent to 240,315 pascals, 2.4 bars, or 1,802 mmHg.
