Pressure
Convert bar (bar) to kilogram-force per square centimetre (kgf/cm²). Pressure is force per unit area. Process engineers move constantly between SI (kPa, bar) and US (psi) units, and between absolute and gauge.
1 bar = 1.019716 kgf/cm²
To convert bar to kilogram-force per square centimetre, multiply the bar value by 1.019716. To go the other way, divide by 1.019716 (or multiply by 0.980665).
| bar | kgf/cm² |
|---|---|
| 1 | 1.019716 |
| 2 | 2.039432 |
| 5 | 5.098581 |
| 10 | 10.19716 |
| 25 | 25.49291 |
| 50 | 50.98581 |
| 100 | 101.9716 |
| 250 | 254.9291 |
| 500 | 509.8581 |
| 1000 | 1019.716 |
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 10 bar is 10.19716 kgf/cm².
Multiply the value in bar by 1.019716 to get kgf/cm². For example, 10 bar = 10.19716 kgf/cm².
1 bar equals 1.019716 kgf/cm².
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.
