Kilopascal to Torr Converter

How do I convert kPa to PSI?

Formula: PSI = kPa × 0.145038 (or kPa ÷ 6.895)

Examples:

• 100 kPa = 14.5 PSI
• 200 kPa = 29 PSI (bicycle tire)
• 220 kPa = 32 PSI (typical car tire)
• 240 kPa = 35 PSI (SUV tire)
• 600 kPa = 87 PSI (road bike)

What is 32 PSI in kPa?

32 PSI = 220.6 kPa (standard car tire pressure)

Common tire pressures:

• 30 PSI = 207 kPa
• 32 PSI = 221 kPa (most common)
• 35 PSI = 241 kPa (SUVs, loaded vehicles)
• 40 PSI = 276 kPa (trucks, some SUVs)

How many kPa in 1 bar?

1 bar = 100 kPa exactly

Examples:

• 0.5 bar = 50 kPa
• 1 bar = 100 kPa
• 2 bar = 200 kPa (bicycle tire)
• 2.5 bar = 250 kPa (car tire)
• 10 bar = 1,000 kPa = 1 MPa

Why do some countries use kPa and others PSI for tires?

kPa (kilopascal): International standard (SI unit)

• Used in: Europe, Asia, Australia, Canada, most of world
• Metric system, easier calculations
• Appears on all tire sidewalls globally

PSI (pounds per square inch): US customary unit

• Used in: United States primarily
• Imperial system, traditional in US
• Also appears on tire sidewalls

Dual labeling: Modern tires show both (e.g., "32 PSI / 220 kPa")

Conversion tip: Multiply kPa by 0.145 to get PSI, or divide PSI by 6.895 to get kPa

Is kPa replacing mmHg for blood pressure?

Transitioning, but slow:

mmHg still dominant: Most medical equipment, patient communication uses mmHg kPa in some regions: SI-compliant medical devices show kPa Dual display: Many modern BP monitors show both

Why slow transition?:

• Historical familiarity (120/80 mmHg)
• Medical education based on mmHg
• Patient understanding
• International guidelines still use mmHg

Conversion: 1 kPa ≈ 7.5 mmHg, so 120/80 mmHg = 16/10.7 kPa (less intuitive)
