What is standard atmospheric pressure in different units?

1 atm = 101,325 Pa = 1,013.25 hPa = 14.696 psi = 1.01325 bar = 760 Torr = 29.92 inHg. Enter 1 in the atm field to see all conversions at once.

What is the Pressure Converter?

The free Pressure Converter supports 10 units: pascals (Pa), hectopascals (hPa), kilopascals (kPa), megapascals (MPa), bar, millibar (mbar), pounds per square inch (psi), standard atmospheres (atm), Torr, and inches of mercury (inHg). Select source and target units, enter a pressure value, and get an instant conversion — plus the full All Conversions table across all 10 units.

→ Converting psi to bar for tyre pressure checks in metric-standard countries
→ Converting hPa to inHg for weather station or barometer readings
→ Converting atm to kPa for chemistry or gas law calculations
→ Converting MPa to psi for hydraulic engineering specifications

How to Use the Pressure Converter

1 Pick the source pressure unit (e.g. psi) from the From dropdown.
