Convert pressure instantly. Switch between pascals, kilopascals, bar, psi, atmospheres, and mmHg, and see the conversion rate in both directions.
Who the Pressure Converter is for
Engineers, divers, and anyone converting pressure between scientific and practical units.
How to use the Pressure Converter
- Type your values into the fields above — pick your currency or units where the calculator offers them.
- Results update automatically as you type; there's no submit button and nothing is sent to a server.
- Adjust any input to compare scenarios, then copy the result with a single click.
How it works
Each unit has a fixed size in pascals. The value is converted to pascals, then to the target unit: result = value × (from-unit Pa) ÷ (to-unit Pa).
Features
- Pa, bar, psi, atm
- mmHg (torr)
- Two-way conversion rate
- Instant result
Pressure units
Pressure is force per area, measured in pascals (SI), bar and atmospheres in science, psi in engineering and tyres, and mmHg in medicine and meteorology. One atmosphere is about 101,325 pascals, 1.013 bar, or 14.7 psi. This converter bridges all these everyday and technical units.
