About the Pressure Converter
Pressure appears in diverse contexts: tyre pressure (PSI or bar), blood pressure (mmHg), atmospheric pressure (hPa in weather), industrial systems (MPa), and cooking (bar in pressure cookers). India uses PSI for tyre pressure and mmHg for blood pressure, while scientific and industrial work uses Pascals. This converter handles all common pressure units instantly.
Pressure Conversion Reference
1 bar = 14.504 PSI = 100,000 Pa = 750.06 mmHg · 1 atmosphere = 1.013 bar = 14.696 PSI
Tyre pressure: 30-35 PSI = 2.07-2.41 bar (car) · Blood pressure: normal 120/80 mmHg · Weather pressure: ~1013 hPa = 1 atm at sea level · Pressure cooker: typically 0.7-1 bar above atmospheric
Worked Example
Car tyre recommended at 32 PSI - what is this in bar?
32 PSI = 2.21 bar · Verify: most Indian cars recommend 2.0-2.5 bar tyre pressure
Tips & Insights
- 1
Tyre pressure gauges in India commonly show both PSI and bar - use the recommended value from your car's manual (often in the door jamb sticker).
- 2
Altitude reduces atmospheric pressure significantly - at 2,000m, pressure is ~0.8 atm, affecting boiling point (water boils at 93°C not 100°C).
- 3
Blood pressure: 120/80 mmHg is normal; above 140/90 is hypertension requiring medical attention.
Why this matters for you
Driving on under-inflated tyres costs 2-3% extra fuel and dramatically increases blowout risk. A tyre at 25 PSI instead of recommended 32 PSI is dangerous - and many drivers do not know their target pressure in both units. For healthcare, converting blood pressure units correctly is critical for reading imported devices or understanding international medical records.
