KG to PSI Converter
Enter pressure in kg/cm² (kilogram-force per square centimeter) to convert instantly to psi (pounds per square inch).
If you work with compressors, hydraulic systems, tire pressure specs, or industrial gauges, you’ve probably seen both kg/cm² and psi. This calculator helps you convert quickly and accurately without manual math.
What does “kg to psi” mean?
In pressure contexts, “kg” usually means kg/cm² (kilogram-force per square centimeter), not plain kilograms of mass. Pressure is force applied over area, so it needs area in the unit.
This page converts:
- kg/cm² → psi
- Where psi stands for pounds-force per square inch
Conversion formula
kg/cm² to psi
psi = kg/cm² × 14.223343307
So if you have 2 kg/cm²:
2 × 14.223343307 = 28.446686614 psi
psi to kg/cm² (reference)
kg/cm² = psi × 0.070306958

Common mistakes to avoid
1) Confusing kg with kg/cm²
Kilograms alone measure mass, not pressure. Always ensure you’re converting pressure units.
2) Rounding too early
If precision matters (engineering, calibration, safety), keep several decimal places until the final result.
3) Mixing gauge and absolute pressure
Unit conversion does not change whether pressure is gauge (relative to atmosphere) or absolute. Confirm your pressure basis before calculations.
FAQ
Is 1 kg/cm² exactly 14.2 psi?
It’s approximately 14.2 psi, but the more accurate factor is 14.223343307.
Can I convert negative values?
Yes. The calculator will still compute mathematically. Negative values may represent vacuum gauge readings in some applications.
Why do some documents just say “kg”?
Many manuals shorten kg/cm² to “kg” informally. For technical clarity, always write the full pressure unit.
Final note
This convert kg to psi calculator is designed for fast day-to-day use and technical accuracy. If you’re preparing engineering documentation, include unit labels directly in your reports to avoid confusion and reduce errors.
