About Pressure Converter
Convert pascals, bar, psi, atmospheres, torr, and mmHg. Tire gauges, HVAC specs, scuba tables, and weather maps all express pressure differently.
How to Use Pressure Converter
Select the pressure unit on the gauge or spec sheet. Enter the reading. Choose the unit needed for your calculation. Document the converted value with units in your report.
When to Use Pressure Converter
Automotive: Compare tire pressure in psi vs bar. HVAC: Read equipment ratings in kPa or inches of water column. Laboratory: Convert mmHg to pascals for gas law problems. Meteorology: Move between hPa, inHg, and kPa for weather data.
Why Use This Pressure Converter?
Pressure units reference different zero points (gauge vs absolute). This tool converts magnitudes; know whether your source is absolute or gauge pressure before interpreting results.
How to use
1. Select the pressure unit on the gauge or spec sheet.
2. Enter the reading.
3. Choose the unit needed for your calculation.
4. Document the converted value with units in your report.
Frequently asked questions
psi vs bar for tire pressure?
Multiply psi by 0.0689476 for bar, or use the dropdown. Car door stickers may list either.
What is standard atmospheric pressure?
About 101.325 kPa, 14.696 psi, or 1 atm—definitions vary slightly by standard.
