Atmospheric pressure, also known as barometric pressure, is the weight of the atmosphere above a specific point on Earth. It is measured as the force per unit area exerted by the weight of the air above that point. The standard atmospheric pressure at sea level is 14.7 pounds per square inch (psi) or 101.325 kilopascals (kPa).
Atmospheric pressure can be expressed in various units, including psi, kPa, atmospheres (atm), millimeters of mercury (mmHg), and inches of mercury (inHg). To convert between these units, use the following conversion factors:
From | To | Conversion Factor | Example |
---|---|---|---|
psi | kPa | Multiply by 6.894757 | 1 psi = 6.894757 kPa |
kPa | psi | Divide by 6.894757 | 1 kPa = 0.1450377 psi |
atm | psi | Multiply by 14.7 | 1 atm = 14.7 psi |
atm | kPa | Multiply by 101.325 | 1 atm = 101.325 kPa |
mmHg | psi | Divide by 51.71493 | 1 mmHg = 0.01933678 psi |
mmHg | kPa | Divide by 7.500616 | 1 mmHg = 1.333224 kPa |
