Convert between all pressure units instantly: pascals, kilopascals, megapascals, bars, millibars, atmospheres, psi, torr, mmHg, inHg, inches of water, and feet of water. Real-time conversion with formulas and reference table.
| Unit | Value |
|---|
1 Pa = 1 Pa = 0.00001 bar = 0.000145 psi = 0.0075 mmHg
1 bar = 1 bar = 100,000 Pa = 14.5038 psi = 750.062 mmHg
1 psi = 1 psi = 6,894.76 Pa = 0.0689476 bar = 51.7149 mmHg
1 atm = 1 atm = 101,325 Pa = 1.01325 bar = 14.6959 psi = 760 mmHg
1 mmHg = 1 mmHg = 133.322 Pa = 0.00133322 bar = 0.0193368 psi
Our free Pressure Converter supports instant conversion between all common pressure units — pascals, kilopascals, megapascals, bars, millibars, atmospheres, psi, torr, mmHg, inHg, inches of water, and feet of water. All calculations happen in your browser — no data is sent to any server. Perfect for engineering, physics, meteorology, medical, and industrial pressure conversions.
Our converter uses exact conversion factors based on international standards (ISO 80000, NIST). Results are accurate to 10 decimal places for all supported units.
Yes! You can convert between any two pressure units — pascals to psi, bar to atmospheres, mmHg to kilopascals, or any other combination.
PSI (pound per square inch) is an imperial unit commonly used in the US for tire pressure, hydraulics, and industrial applications. Bar is a metric unit equal to 100,000 pascals, widely used in Europe and scientific contexts. 1 bar ≈ 14.5038 psi.
