🌊 Common Pressure References

Standard atmosphere1 atm | 14.7 PSI
Car tire pressure2.2 Bar | 32 PSI
Bicycle tire4.5 Bar | 65 PSI
Blood pressure (systolic)120 mmHg
Deep sea (10m depth)2 Bar | 29 PSI
💡 Quick Trick: To convert Bar to PSI quickly, multiply by 14.5 (approximate). For PSI to Bar, divide by 14.5. 1 atm ≈ 1 Bar ≈ 100 kPa.

📊 Why Use a Pressure Converter?

Pressure conversion is essential in many fields - from engineering and manufacturing to meteorology, medicine, and scuba diving. Whether you're checking tire pressure, monitoring blood pressure, working with hydraulic systems, or studying weather patterns, accurate pressure conversion is crucial for safety and precision.

🔧 Engineering

Hydraulic systems, pneumatic tools, pressure vessels, and pipelines use Bar, PSI, and MPa.

🌪️ Meteorology

Atmospheric pressure is measured in hPa, mbar, or inHg for weather forecasting.

🏥 Medicine

Blood pressure is measured in mmHg. Oxygen tanks use PSI.

🤿 Diving

Scuba tanks use PSI or Bar. Depth pressure increases by 1 atm every 10m.

❓ Frequently Asked Questions

What's the difference between Bar and PSI?

Bar is a metric unit (1 Bar = 100,000 Pascals), while PSI (Pounds per Square Inch) is an imperial unit. 1 Bar ≈ 14.5 PSI. Bar is commonly used in Europe and automotive industries, while PSI is standard in the US.

What is standard atmospheric pressure?

Standard atmospheric pressure (1 atm) at sea level is defined as 101,325 Pascals, which equals 1.01325 Bar, 14.6959 PSI, 760 mmHg, or 29.92 inHg.

How do I convert tire pressure from Bar to PSI?

Multiply the Bar value by 14.5038. For example, 2.2 Bar × 14.5038 = 31.9 PSI (typical car tire pressure). Most tire gauges show both units.

What's the difference between Torr and mmHg?

Torr and mmHg are nearly identical (1 Torr = 1 mmHg). Both are used in vacuum measurements and barometric pressure. The difference is only 1 part in 7.6 million, negligible for most purposes.

⚠️ Disclaimer: All conversions are based on standard international definitions. For critical applications like medical devices or high-pressure systems, always use calibrated instruments.
