Pressure
Convert kilogram-force per square centimetre (kgf/cm²) to bar (bar). Pressure is force per unit area. Process engineers move constantly between SI (kPa, bar) and US (psi) units, and between absolute and gauge.
1 kgf/cm² = 0.980665 bar
To convert kilogram-force per square centimetre to bar, multiply the kgf/cm² value by 0.980665. To go the other way, divide by 0.980665 (or multiply by 1.019716).
| kgf/cm² | bar |
|---|---|
| 1 | 0.980665 |
| 2 | 1.96133 |
| 5 | 4.903325 |
| 10 | 9.80665 |
| 25 | 24.51663 |
| 50 | 49.03325 |
| 100 | 98.0665 |
| 250 | 245.1662 |
| 500 | 490.3325 |
| 1000 | 980.665 |
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 10.19716 kgf/cm² is 10 bar.
Multiply the value in kgf/cm² by 0.980665 to get bar. For example, 10 kgf/cm² = 9.80665 bar.
1 kgf/cm² equals 0.980665 bar.
