Instant kg to psi Converter
Use this tool to convert pressure between kg/cm² (kilogram-force per square centimeter) and psi (pounds per square inch).
Tip: In many engineering contexts, people say “kg” but actually mean kg/cm² for pressure.

kg to psi formula
From kg/cm² to psi
psi = kg/cm² × 14.223343307
From psi to kg/cm²
kg/cm² = psi ÷ 14.223343307
This conversion factor is based on standard gravity and standard pressure unit definitions used in engineering and industrial measurements.
Example conversions
- 1 kg/cm² = 14.223 psi
- 2.5 kg/cm² = 35.558 psi
- 50 psi = 3.515 kg/cm²
- 100 psi = 7.031 kg/cm²

Why “kg to psi” can be confusing
Strictly speaking, kg is a unit of mass, while psi is a unit of pressure. So a direct conversion from mass to pressure is not physically correct unless area and force context are defined. In practice, many technicians and users use “kg” as shorthand for kg/cm² (kilogram-force per square centimeter), and that is the convention used in this calculator.
Where this conversion is commonly used
- Air compressor pressure settings
- Hydraulic and pneumatic systems
- Industrial gauges and pump calibration
- Boiler and process equipment specifications
FAQ
Is kg/cm² the same as bar?
No. They are close but not identical. 1 kg/cm² is about 0.980665 bar.
Can I use this for tire pressure?
Yes, if your source value is in kg/cm² and your target is psi. Always follow the manufacturer’s recommended pressure range.
Does this calculator support negative values?
Yes. Negative values can represent vacuum or gauge pressure below atmospheric pressure in some systems.
