Pressure
Convert megapascal (MPa) to kilopascal (kPa). Pressure is force per unit area. Process engineers move constantly between SI (kPa, bar) and US (psi) units, and between absolute and gauge.
1 MPa = 1000 kPa
To convert megapascal to kilopascal, multiply the MPa value by 1000. To go the other way, divide by 1000 (or multiply by 0.001).
| MPa | kPa |
|---|---|
| 1 | 1000 |
| 2 | 2000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |
| 250 | 250000 |
| 500 | 500000 |
| 1000 | 1000000 |
Line and vessel ratings, pump discharge heads, and relief set points are all specified in pressure units — usually psi or barg in the field and kPa in calculations.
Always track whether a value is absolute or gauge: 0 barg equals about 101.3 kPa absolute, and mixing the two is a common and costly error.
Worked example. A pressure of 1 MPa is 1000 kPa.
Multiply the value in MPa by 1000 to get kPa. For example, 10 MPa = 10000 kPa.
1 MPa equals 1000 kPa.
