Pressure
Convert kilopascal (kPa) to millibar (mbar). Pressure is force per unit area. Process engineers move constantly between SI (kPa, bar) and US (psi) units, and between absolute and gauge.
1 kPa = 10 mbar
To convert kilopascal to millibar, multiply the kPa value by 10. To go the other way, divide by 10 (or multiply by 0.1).
| kPa | mbar |
|---|---|
| 1 | 10 |
| 2 | 20 |
| 5 | 50 |
| 10 | 100 |
| 25 | 250 |
| 50 | 500 |
| 100 | 1000 |
| 250 | 2500 |
| 500 | 5000 |
| 1000 | 10000 |
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 1000 kPa is 10000 mbar.
Multiply the value in kPa by 10 to get mbar. For example, 10 kPa = 100 mbar.
1 kPa equals 10 mbar.
