Method
Pressure values are converted through standard factors between pascals, bar, PSI, atmospheres, torr, and mmHg.

Torr and mmHg use their respective formal definitions — not interchanged.

1 Kilopascal (kPa) = 0.1450 PSI (pound-force per square inch)
Torr and mmHg use separate definitions that differ by less than 0.000015%. Standard atmosphere (atm) = 101,325 Pa exactly.
Useful context
How it works
Use the calculator first, then scan the details below when you want more context about the inputs, result, or assumptions.
How to use it
Enter a pressure, select the input unit, and compare the converted readings.
Understand the result
Each output describes the same force per area in a different unit system.
Example
1 atmosphere is approximately 14.696 PSI.
Notes
Use the formal unit labels carefully: torr and mmHg are not silently treated as interchangeable.
