The standard pressure in a standard atmosphere is 1 atmosphere.
According to the provided reference, the average atmospheric pressure, also known as standard atmospheric pressure, is equivalent to several values, including 1 atmosphere. The reference gives other equivalent measures:
- 14.7 psi (pounds per square inch)
- 101.3 kPa (kilopascals)
- 760 mm of mercury
This shows the standard atmospheric pressure can be expressed in different units, but it's directly 1 atmosphere when using the 'atmosphere' unit.
Here is a table summarizing standard atmospheric pressure in different units:
| Unit | Value |
|---|---|
| Atmosphere (atm) | 1 |
| Pounds per square inch (psi) | 14.7 |
| Kilopascals (kPa) | 101.3 |
| Millimeters of mercury (mm Hg) | 760 |
The reference also provides information about pressure units in general:
- Pressure is a force applied over a given area, represented by the formula p = F/A.
- Common units for pressure include pounds per square foot (psf), pounds per square inch (psi), and pascals (Pa or N/m2).
Understanding standard atmospheric pressure is important in various scientific and engineering applications. It provides a reference point for measuring and comparing pressure in different environments.
