모든 단위 변환
Overview
Convert between atmospheres (atm), pascals (Pa), PSI, bar, mmHg, and Torr. Used in tire pressure, weather observation, engineering, and scientific applications.
Formula
1 atm = 101,325 Pa = 101.325 kPa 1 atm = 14.6959 psi 1 atm = 1.01325 bar 1 atm = 760 mmHg = 760 Torr 1 bar = 100,000 Pa = 14.5038 psi 1 psi = 6894.76 Pa = 0.0689476 bar

Tips
- ✔Car tire pressure is typically 30-35 psi (approximately 207-241 kPa).
- ✔Blood pressure is measured in mmHg (millimeters of mercury).
- ✔Standard atmospheric pressure (1 atm) is the average air pressure at sea level.
- ✔In engineering, 1 MPa = 10 bar = 145.038 psi.
FAQ
Q. How do I convert psi to kPa for tire pressure?
Multiply psi by 6.895 to get kPa. For example, 32 psi × 6.895 = approximately 220.6 kPa.
Q. What is hPa used in weather forecasts?
hPa (hectopascal) is used in meteorology for atmospheric pressure. 1 hPa = 100 Pa = 1 mbar. Standard atmospheric pressure is about 1013.25 hPa.
Q. Are mmHg and Torr the same?
Practically yes. 1 Torr is defined as exactly 101,325/760 Pa, and 1 mmHg is the pressure exerted by 1 mm of mercury under standard gravity. The difference is negligible for most applications.
