Understanding Pound per Square Inch and Bar
Pound per Square Inch (psi)
The pound per square inch is a unit of pressure in the Imperial system.
• 1 PSI = 6.89476 kPa
• 1 PSI = 0.0689476 bar
• Common for tire pressure in the US
• Used in hydraulic systems and plumbing
Bar (bar)
The bar is a unit of pressure in the Metric system.
• 1 bar = 100,000 pascals
• Standard for European tire pressure
• Used in meteorology (millibars)
• Common in compressed air systems
Imperial to Metric Conversion
You are converting from a imperial unit to a metric unit. This is a common conversion needed when:
- Working with international equipment specifications
- Using tools or vehicles from different countries
- Following international standards and regulations
- Collaborating on international projects
- Converting medical or scientific data
Practical Examples
Everyday Use
- • Car tire pressure (30-35 PSI) = 2.07-2.41 bar
- • Bicycle tire pressure (60-100 PSI) = 4.14-6.89 bar
- • Basketball pressure (7-9 PSI) = 0.48-0.62 bar
Professional Use
- • Hydraulic system pressure (3000 PSI) = 206.8 bar
- • Industrial compressed air (100 PSI) = 6.89 bar
- • Oil pipeline pressure (1500 PSI) = 103.4 bar
Conversion Tips
Quick Mental Calculation
For approximate conversions, remember these quick multipliers:
- Divide by 14.5 for quick PSI to bar
- 10 PSI ≈ 0.69 bar
- 100 PSI ≈ 6.9 bar
