kg/cm² to psi Converter

Many older compressors, hydraulic presses, and Asian-market gauges report pressure in kg/cm². North American documentation, however, is almost always psi. This converter bridges the two and shows kPa/Pa references.

Constants used

• $1\,\text{kgf/cm}^2 = 98{,}066.5\,\text{Pa}$
• $1\,\text{psi} = 6{,}894.757\,\text{Pa}$
• Therefore $1\,\text{kgf/cm}^2 \approx 14.2233\,\text{psi}$

Units and conversions

Worked examples

1. 1 kg/cm² → psi
   $1 \times 98{,}066.5 / 6{,}894.757 \approx 14.2233\,\text{psi}$.

2. 100 psi → kg/cm² $100 \times 6{,}894.757 / 98{,}066.5 \approx 7.03\,\text{kg/cm}^2$.

3. 7 kg/cm² → kPa $7 \times 98.0665 \approx 686.47\,\text{kPa}$.

Tips and pitfalls

• kg/cm² uses kilogram-force, not kilogram-mass; that is the standard gauge convention.
• If you need absolute pressure, add atmospheric pressure (≈14.7 psi) to psig before converting.
• Keep three decimals when sizing hydraulic components or pressure vessels.
