Quick tips
- 1 atmosphere = 101,325 Pa = 14.696 PSI = 1.01325 bar.
- Tire pressure is usually measured in PSI (US) or bar (Europe).
- mmHg and Torr are nearly identical — both used in medicine for blood pressure readings.
FAQ
Frequently asked questions
What is 1 atm in PSI?
1 standard atmosphere equals approximately 14.696 PSI.
What is the difference between Torr and mmHg?
They are nearly identical. 1 Torr ≈ 1 mmHg. Technically 1 Torr = 101,325/760 Pa, and 1 mmHg depends on gravity and mercury density, but the difference is negligible for practical use.
What unit is used for blood pressure?
Blood pressure is measured in mmHg (millimeters of mercury). A normal reading is around 120/80 mmHg.
What is a Pascal?
The SI unit of pressure, equal to one newton per square meter. It is named after Blaise Pascal. Standard atmospheric pressure is 101,325 Pa.
