Kilopascal (kPa) and atmosphere (atm) are units of pressure commonly used in various scientific and engineering applications. One standard atmosphere (atm) is defined as the average pressure at sea level on Earth, which is approximately equal to 101.325 kPa.
| Kilopascals (kPa) | Atmospheres (atm) |
|---|---|
| 1 kPa | 0.00987 atm |
| 10 kPa | 0.0987 atm |
| 50 kPa | 0.4935 atm |
| 101.325 kPa | 1 atm |
| 200 kPa | 1.974 atm |
| 500 kPa | 4.935 atm |
| 1000 kPa | 9.87 atm |
To convert kilopascals (kPa) to atmospheres (atm), multiply the kPa value by 0.00987.
Formula: ATM = kPa × 0.00987
Let's convert 250 kPa to atm:
250 kPa × 0.00987 = 2.47 atm
These pressure units are commonly used in:
1. The standard atmosphere (atm) is defined as 101.325 kPa at sea level.
2. The kilopascal is part of the International System of Units (SI).
3. Atmospheric pressure decreases with altitude above sea level.
