About Pressure Converter

Pressure measures force per area and appears in tire inflation, blood pressure contexts (with clinical devices), weather maps, and industrial systems. Units range from pascals to bars, PSI, atmospheres, torr, and millimeters of mercury.

CalculatorCamp pressure converter applies standard conversion factors between common engineering and scientific units.

Always follow equipment manuals and medical guidance; online conversion is for reference and education, not diagnosis or safety certification.

How to use this tool

Enter the pressure reading, choose its unit, and select the target unit. Calculate to view the equivalent pressure.

Formula & methodology

This pressure unit converter applies the standard relationship below. Intermediate values are kept at full precision; only the displayed result is rounded.

1 bar = 100,000 Pa; 1 atm = 101,325 Pa; 1 PSI = 6894.76 Pa; 760 Torr ~ 1 atm

Tips for accurate results

  • Tire gauges may read gauge pressure, not absolute—compare like with like.
  • Weather hPa is equivalent to mbar for practical conversion.
  • Vacuum ratings may be negative gauge; confirm sign convention on your gauge.
  • Do not use converted values alone for medical treatment decisions.

Frequently asked questions

Is bar the same as atmosphere?

Close in magnitude but not identical; 1 atm is defined as 101325 Pa.

Can PSI convert to kPa?

Yes. Pick PSI as from-unit and kPa as to-unit.

What is mmHg used for?

Historically linked to mercury manometers and blood pressure notation in some regions.

Free tool?

Yes.
