Understanding the Basics of Atmospheric Pressure
Atmospheric pressure, also known as air pressure, is the weight of the air in the Earth’s atmosphere pushing down on the surface. It is measured in units of pressure, such as pascals (Pa), millibars (mbar), or atmospheres (atm). The standard atmosphere (atm) is defined as 101,325 Pa, which is the average atmospheric pressure at sea level.
Conversion Factor: 1 atm to SI Units
The conversion from 1 atm to SI units is straightforward. Since 1 atm is equal to 101,325 Pa, we can use this conversion factor to convert between the two units. This means that any pressure measured in atm can be easily converted to Pascals (Pa) by multiplying it by 101,325.
| Unit | Conversion Factor |
|---|---|
| 1 atm | 101,325 Pa |
| 1 Pa | 0.0000098692 atm |
