⚡ Pro Tips for Pressure Conversions

1
Remember Key Conversions
1 bar ≈ 14.5 PSI, 1 atm = 101,325 Pa, 1 PSI ≈ 6,895 Pa. These help with quick estimates.
2
Tire Pressure Standards
US uses PSI, Europe uses bar. Typical car tire pressure: 30-35 PSI (2.0-2.4 bar).
3
Use Quick Buttons
Click the quick conversion buttons for instant PSI ↔ bar conversions without selecting units.
4
Absolute vs Gauge Pressure
Gauge pressure (PSIG) measures relative to atmospheric pressure. Absolute pressure (PSIA) includes atmospheric pressure.

🎓 Understanding Pressure Units

Common Pressure Units

  • Pascal (Pa): SI unit of pressure, 1 Pa = 1 N/m²
  • Bar: Metric unit, 1 bar = 100,000 Pa, approximately 1 atmosphere
  • PSI (Pounds per Square Inch): Imperial unit, common in US (1 PSI ≈ 6,895 Pa)
  • Atmosphere (atm): Standard atmospheric pressure at sea level (101,325 Pa)
  • Torr: 1/760 of an atmosphere, used in vacuum measurements
  • Inches of Mercury (inHg): Used in weather and aviation

Typical Pressure Values

  • Car Tire: 30-35 PSI (2.0-2.4 bar)
  • Bicycle Tire: 40-80 PSI (2.8-5.5 bar)
  • Atmospheric Pressure: 14.7 PSI (1.01 bar, 1 atm)
  • High Pressure Washer: 1,500-3,000 PSI (100-200 bar)
  • Scuba Tank: 3,000 PSI (200 bar)
🌤️ Real-World Example: Weather Forecast

Situation: A weather report shows barometric pressure of 1013 millibars, but you're used to inches of mercury.

Solution: Convert 1013 mbar to inHg: 29.91 inches of mercury. This is normal atmospheric pressure - expect fair weather!

❓ Frequently Asked Questions (FAQ)

How do I convert PSI to bar?
Divide PSI by 14.5038 to get bar. For example: 30 PSI ÷ 14.5038 = 2.07 bar. Our converter does this automatically.
How do I convert bar to PSI?
Multiply bar by 14.5038 to get PSI. For example: 2 bar × 14.5038 = 29.01 PSI.
What's the difference between PSI and PSIG?
PSI typically refers to gauge pressure (PSIG), which measures pressure relative to atmospheric pressure. PSIA is absolute pressure, which includes atmospheric pressure. PSIA = PSIG + 14.7.
What is standard atmospheric pressure?
Standard atmospheric pressure at sea level is 1 atmosphere (atm), which equals 101,325 pascals, 1.01325 bar, 14.7 PSI, or 760 torr.
Can I convert between any two units?
Yes! Our converter supports conversions between all available pressure units - metric to imperial, scientific to practical, or within the same system.
How accurate are the conversions?
Our conversions use standard conversion factors and are accurate to multiple decimal places. The precision is suitable for automotive, scientific, and professional applications.
What tire pressure should I use?
Check your vehicle's door jamb or owner's manual for recommended tire pressure. Typical values are 30-35 PSI (2.0-2.4 bar) for passenger cars.
Will this work on my phone?
Yes! The pressure converter is fully responsive and works perfectly on smartphones and tablets. All features are available on mobile devices.
Why is bar used in Europe?
Bar is a metric unit that's close to atmospheric pressure (1 bar ≈ 1 atm), making it convenient for practical applications. It's widely used in Europe for tire pressure and industrial applications.
Can I use this for scuba diving calculations?
Yes! The converter is perfect for scuba tank pressures, depth calculations, and understanding pressure changes underwater. Convert between PSI, bar, and atmospheres easily.
