Instant kg/cm² to PSI Calculator
Enter a pressure value and convert it in one click. By default, this tool converts kg/cm² to psi. You can also switch direction and convert psi back to kg/cm².
What does “kg to psi” mean?
In pressure conversion, “kg to psi” usually means converting kg/cm² (kilogram-force per square centimeter) into psi (pounds per square inch). This is very common in automotive specs, industrial machinery, and fluid systems.
Technically, kilograms measure mass, not pressure. But in everyday engineering usage, people shorten “kg/cm²” to “kg.” This calculator uses the standard pressure interpretation.
kg/cm² to psi conversion formula
The exact conversion factor is:
1 kg/cm² = 14.223343307 psi
So the main formula is:
psi = kg/cm² × 14.223343307
Reverse formula:
kg/cm² = psi ÷ 14.223343307
Quick conversion table
| kg/cm² | psi |
|---|---|
| 0.1 | 1.4223 |
| 0.5 | 7.1117 |
| 1 | 14.2233 |
| 2 | 28.4467 |
| 5 | 71.1167 |
| 10 | 142.2334 |

Where this conversion is used
- Tire pressure: Some gauges and manuals use psi, others use kg/cm².
- Hydraulic systems: Pump, valve, and cylinder specifications often mix unit systems.
- Compressors and pneumatics: Operating pressure may be listed in either metric or imperial units.
- Boilers and process equipment: Pressure ratings must be converted accurately for safety compliance.
Examples
Example 1: Convert 3 kg/cm² to psi
3 × 14.223343307 = 42.6700 psi
Example 2: Convert 36 psi to kg/cm²
36 ÷ 14.223343307 = 2.5318 kg/cm²
Common mistakes to avoid
- Confusing kg (mass) with kg/cm² (pressure).
- Rounding too early, especially in safety-critical calculations.
- Mixing up bar and kg/cm² without checking the exact relationship.
- Using old approximations when exact conversion factors are required by code or standards.
FAQ
Is kg/cm² the same as bar?
No. They are close but not identical. 1 kg/cm² is approximately 0.980665 bar.
Can I convert plain kilograms (kg) directly to psi?
Not without area. Pressure requires force distributed over an area. You need a pressure unit such as kg/cm², kg/m², or Pa.
How many psi is 1 kg/cm²?
Exactly 14.223343307 psi.
