Frequently Asked Questions
Standard atmospheric pressure is 1 atm = 101,325 Pa = 1.01325 bar = 14.696 psi = 760 mmHg = 760 Torr = 29.92 inHg. This is the reference pressure at sea level.
PSI (pounds per square inch) is primarily used in the US, while Bar is used in Europe and scientifically. 1 bar = 14.5038 psi. For tire pressure: a car tire at 30 psi is about 2.07 bar.
mmHg (millimeters of mercury) is used in medicine for blood pressure measurements and in barometric pressure readings. Normal blood pressure is about 120/80 mmHg. It equals 1 Torr.
Pascal (Pa) is the SI unit of pressure equal to 1 newton per square meter (N/m²). Named after Blaise Pascal, it's the standard scientific unit, though derived units like kPa and MPa are often more practical.
