About this converter
How to use Pressure Converter, plus the formulas and logic behind the results.
Tool description
The Pressure Converter translates readings among pascal, kilopascal, bar, psi, atmosphere, torr, and mmHg. It is useful for tires, weather, and industrial gauges. It does not distinguish gauge pressure from absolute pressure.
How to use
- Enter the pressure reading.
- Select the unit shown on your gauge or data source.
- Select the unit you need.
- Select Convert to view the result and the same pressure in all listed units.
Formulas
base Pa = input × factor of the source unitoutput = base Pa ÷ factor of the target unit1 bar = 100,000 Pa, 1 atm = 101,325 Pa, 1 psi ≈ 6,894.757 Pa
Quick reference
- 1 bar = 100,000 pascals
- 1 atm = 101,325 pascals
- 1 psi ≈ 6,894.76 pascals
- 1 torr ≈ 133.322 pascals
Calculation logic
Pressure is converted to pascals (N/m²), then to the target unit. Torr and mmHg use the same conversion factor in this tool for practical comparison.
Standard atmospheric pressure is defined as 101,325 Pa. Gauge pressure applications may require additional context.
Pressure Converter FAQ
Common questions about this converter and how to use the results.
How do I convert psi to bar?
Divide psi by 14.5038. For example, 30 psi ≈ 2.068 bar.
What is a pascal?
A pascal (Pa) is the SI unit of pressure, equal to one newton per square meter.
What is atmospheric pressure in atm?
One standard atmosphere (1 atm) equals 101,325 Pa.
Are torr and mmHg the same?
For practical conversions they are treated as equal in this tool.
Where is psi commonly used?
PSI is widely used for tire pressure and many US industrial gauges.
