About the Pressure Converter
The Pressure Converter converts a pressure value between units such as pascals, bar, PSI, atmospheres, torr, millimeters of mercury, and kilopascals. Enter one value, pick the units, and you get the equivalent pressure in your chosen unit instantly.
The tool uses fixed conversion factors defined by international standards, anchored to the pascal as the SI base unit. For example, 1 bar equals 100,000 Pa, 1 atmosphere equals 101,325 Pa, and 1 PSI equals 6,894.757 Pa. It multiplies your input by the factor for the source unit, then divides by the factor for the target unit. A practical tip: match the unit to your context, since tire pressure uses PSI while scientific work usually uses pascals or bar.
