Pressure Converter
Convert pascals, bar, psi, and atmospheres.
Pressure units, converted
Pressure appears as pascals in science, bar in weather, and psi on a tyre gauge. One atmosphere is 101,325 pascals, about 14.7 psi — the baseline sea-level pressure.
It covers tyre gauges in psi, weather reports in millibars, scuba and industrial specs in bar, and physics problems in pascals, all of which describe the same quantity differently.
Gauge vs absolute
Tyre and tank gauges read pressure above atmospheric, so add one atmosphere for absolute. The math runs entirely in your browser. The math runs in your browser and is never uploaded.
Frequently Asked Questions
How does the pressure converter work?
Pressure values convert through pascals. A 32 psi tire pressure is about 2.206 bar.
When should I use this converter?
Useful for tire pressure, HVAC notes, weather references, lab work, espresso machines, and international equipment specs.
What is the main limitation?
Temperature and altitude can affect real-world pressure readings; this is a unit conversion, not a sensor calibration.
Is this converter private?
Yes. The conversion runs entirely in your browser, so your values are not uploaded, stored, or sent to a server.
