About Kilopascal and PSI
Kilopascals (kPa) are the SI unit for pressure, while PSI is common in American engineering. One kPa equals approximately 0.145 PSI. Many scientific and international specifications use kPa.
Common Uses for This Conversion
International engineering specifications, tire pressure in some countries (Australia uses kPa), weather data interpretation, and medical blood pressure context.
💡Did You Know?
Normal blood pressure is about 120/80 mmHg, which equals about 16/11 kPa or 2.3/1.5 PSI. Medical contexts typically use mmHg for historical reasons—early devices used mercury columns.
Frequently Asked Questions
To convert PSI (pounds per square inch) to bar, multiply by 0.0689476. For example, 30 PSI = 30 × 0.0689476 = 2.07 bar. To convert bar to PSI, multiply by 14.5038.
Standard atmospheric pressure at sea level equals: 101,325 pascals (Pa), 1.01325 bar, 1 atmosphere (atm), 14.696 PSI, 760 mmHg (torr), or 29.92 inches of mercury. These values are useful for weather forecasting and altitude calculations.
To convert bar to PSI, multiply by 14.5038. For example, 2 bar = 2 × 14.5038 = 29.01 PSI. Tire pressures are often given in PSI (US) or bar (Europe), so this conversion is useful for travelers.
Absolute pressure is measured relative to a perfect vacuum (0 Pa). Gauge pressure is measured relative to atmospheric pressure. For example, a tire at 32 PSI gauge pressure is actually at about 46.7 PSI absolute (32 + 14.7 atmospheric).
