About psi and kgf/cm² (technical)
Psi (pounds per square inch) is the standard pressure unit in the US and UK, while kgf/cm² (kilogram-force per square centimeter) was the standard pressure unit across much of Continental Europe, Japan, and Latin America before the SI system's Pascal and bar became dominant. Both measure the same underlying quantity -- force divided by area -- just using different force and area units, which is why the conversion factor (0.0703069) reflects the ratio between pounds/inches and kilograms-force/centimeters.
Pressure units in engineering and industry
Working with legacy and imported equipment
Older Continental European and Japanese industrial equipment, hydraulic gauges, and technical manuals frequently specify pressure in kgf/cm² rather than the psi used in US/UK equipment or the bar/kPa used in modern SI-standardized specifications. Engineers maintaining or importing this equipment need to convert kgf/cm² figures to match whatever unit their own gauges and documentation use.
Comparing across the pressure-unit family
Pressure shows up in psi (tire gauges, US plumbing), bar (European tire gauges, most industrial contexts), kPa (SI scientific standard), and kgf/cm² (legacy engineering) -- all describing the same physical concept. Roughly: 1 bar ≈ 14.5 psi ≈ 1.02 kgf/cm² ≈ 100 kPa, which is a useful mental anchor when moving between specifications from different regions or eras.
Hydraulic and pneumatic system safety
Matching a hydraulic pump's rated output pressure against a hose, seal, or fitting's maximum pressure rating is a safety-critical calculation -- getting a unit conversion wrong when the two specifications use different pressure units (psi vs kgf/cm², for instance) can lead to equipment operating well beyond its rated limits.
1 psi = 0.0703 kgf/cm². The kgf/cm² unit is used in older Continental European engineering standards and in some industrial processes. Japanese hydraulic equipment often specs pressure in kgf/cm² rather than bar or Pa.

Frequently asked questions
How do I convert psi to kgf/cm² (technical)?
To convert psi to kgf/cm² (technical), multiply by 0.0703069. Or use the calculator above for instant results.
How many kgf/cm² (technical) are in 1 psi?
1 psi equals 0.0703069 kgf/cm² (technical).
Is the psi to kgf/cm² (technical) converter free?
Yes, the psi to kgf/cm² (technical) converter is completely free with no sign-up required, no downloads, and it works offline once the page has loaded.
Why is kgf/cm² still used if it's not an SI unit?
kgf/cm² predates the modern SI system and was standard in much of Continental Europe, Japan, and Latin America before Pascals and bar took over. Older industrial equipment and legacy gauges often still use it.
How does psi compare to bar and kPa?
1 bar equals approximately 14.5 psi, and 1 psi equals approximately 6.895 kPa. Bar is common for European tire gauges, while kPa is the formal SI scientific unit.
What is a typical psi range for car and bike tires?
Passenger car tires typically run 30-35 psi, road bike tires 40-80 psi, and mountain bike tires 20-35 psi. Always check the manufacturer's specific recommendation.
Why do hydraulic systems specify pressure so precisely?
Hydraulic systems rely on precise pressure for controlled force -- too little and equipment won't work; too much can damage seals or hoses. Unit-conversion accuracy matters when cross-referencing components specified in different units.
