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.
