The Kilograms per Square Centimeter to PSI Converter converts pressure from kgf/cm² (kilograms-force per square centimeter) to pounds per square inch (PSI). The conversion factor is 1 kgf/cm² = 14.2233 PSI. This unit is identical to the technical atmosphere (at) and is widely used in Asian and some European countries for tire pressure, material testing, and industrial applications.
The kgf/cm² is particularly common in Japan, South Korea, China, and India, where pressure gauges for industrial equipment, tire inflation, and hydraulic systems often display readings in this unit. Japanese industrial standards (JIS) historically used kgf/cm² extensively, and although SI adoption is progressing, many existing gauges and specifications still use this unit.
In materials testing, older specifications and test reports may express tensile strength, compressive strength, and hardness values in kgf/cm² or kgf/mm². For example, a bolt specification stating '50 kgf/cm²' (711 PSI) needs conversion for comparison with American ASTM standards that use PSI. In tire manufacturing, some Asian brands specify inflation pressure in kgf/cm² alongside kPa and PSI.
The unit is sometimes informally written as 'kg/cm²' with the force component implied, though the correct notation is kgf/cm² to distinguish force (kgf) from mass (kg). Since 1 kgf = 9.80665 N (exact, using standard gravity), the conversion to SI Pascals is: 1 kgf/cm² = 9.80665 N / 0.0001 m² = 98,066.5 Pa. Our converter also provides bar output for European engineering compatibility.
The formula: PSI = kgf/cm² × 14.2233. Since 1 kgf/cm² = 98,066.5 Pa and 1 PSI = 6,894.757 Pa: factor = 98,066.5 / 6,894.757 ≈ 14.2233.
For bars: bar = kgf/cm² × 0.980665.
Common conversions: 1 kgf/cm² = 14.2233 PSI = 0.981 bar = 98,067 Pa. Tire pressure: 2.2 kgf/cm² ≈ 31.3 PSI. Pressure cooker: 1 kgf/cm² above atm ≈ 14.2 PSI gauge.

1 kgf/cm² = 14.2233 PSI. This is the same as 1 technical atmosphere (at).
PSI = kgf/cm² × 14.2233. For example, 3 kgf/cm² = 42.67 PSI.
In practice, yes — when 'kg/cm²' is used as a pressure unit, it implies kilogram-force (kgf). Strictly, kg is mass and kgf is force, but the shorthand 'kg/cm²' is common in everyday use.
Japan, South Korea, China, India, and some European countries. It appears on pressure gauges, tire specifications, and industrial equipment from these regions.
2.5 kgf/cm² = 35.56 PSI. This is a common tire pressure specification on Asian-manufactured vehicles.
1 kgf/cm² = 0.980665 bar. They are very close — kgf/cm² is about 2% less than 1 bar.
kgf/mm² is used for material strengths. 1 kgf/mm² = 100 kgf/cm² = 1,422.33 PSI = 9.807 MPa.
Read the pressure value directly from the gauge dial. To convert to PSI, multiply by 14.2233. To convert to bar, multiply by 0.981.
Many countries are transitioning to SI units (Pa, kPa, MPa, bar). However, kgf/cm² remains in wide practical use, especially on existing equipment and in everyday commercial applications.
The conversion factor (14.2233) is accurate to 6 significant figures. The underlying definition uses exact values: 1 kgf = 9.80665 N and 1 cm = 0.01 m.
