Pressure units are industry-specific: tires and hydraulics in psi, industrial systems in bar, weather in inches of mercury, medicine and vacuum work in mmHg. This converter switches between pascals, bar, pounds per square inch, atmospheres, torr/mmHg and inches of mercury, with reference points on the page (1 atm = 101,325 Pa; 760 mmHg = 1 atm) that anchor the scales to each other. It serves engineering, science, weather forecasting and HVAC work, where a pressure figure usually has to be translated before it can be used.
Use it to interpret equipment ratings, convert barometric readings, or check specifications that mix US, UK and metric documentation. Free on any device, with no sign-up.
Pascals (Pa), bar, pounds per square inch (psi), atmospheres (atm), torr/mmHg and inches of mercury (inHg).
1 bar = 14.5038 psi — so 500 psi = 34.47 bar. The converter handles all combinations instantly.
In vacuum systems and medicine (for example blood pressure), and inHg in meteorology and aviation.
