Understanding kg/cm² and PSI
Pressure measurement relies on different unit systems depending on regional standards and industry practices. The kilogram-force per square centimeter (kgf/cm², commonly shortened to kg/cm²) is a metric unit that quantifies the force of one kilogram distributed over a one‑square‑centimeter area. Its imperial counterpart, pounds per square inch (psi), measures the force of one pound applied to a one‑square‑inch surface. Fields such as automotive tire maintenance, hydraulic engineering, and material testing frequently require switching between these two scales. A free online kg/cm² to PSI converter eliminates guesswork and provides instant, precise results. This tool functions both as a dedicated kilogram per square centimeter to PSI conversion calculator and as a broader pressure unit conversion online utility.
How the Converter Works
The interface is built for simplicity and speed:
- Enter a pressure value in kg/cm² (or psi) into the designated input field.
- The equivalent value in the other unit appears immediately, with no need to press extra buttons.
- The converter supports two‑way conversion: input psi to get kg/cm², or input kg/cm² to get psi.
This flexibility makes it suitable for engineers, technicians, and anyone who routinely performs pressure unit conversions.
The Conversion Formulas
The core relationship between these two pressure units is defined by a constant factor derived from the definitions of the kilogram‑force and the inch. The formulas are:
Converting kg/cm² to psi:
Converting psi to kg/cm²:
The multiplier 14.22334 comes from the conversion between kilogram‑force and pound‑force (1 kgf ≈ 2.20462 lb) and between square centimeter and square inch (1 cm² ≈ 0.1550 in²). Combining these yields the precise factor used in both formulas.
Practical Examples
Using the conversion formulas is straightforward. The table below illustrates a few common values:
| kg/cm² | PSI (approx.) |
|---|---|
| 1 | 14.22 |
| 5 | 71.12 |
| 7 | 99.56 |
| 10 | 142.23 |
For a specific calculation, take a hydraulic system rated at 7 kg/cm². Applying the formula:
The converter confirms this instantly. For the reverse direction, converting 9 psi to kg/cm² gives:
These conversions are essential when comparing equipment specifications across different unit systems or when interpreting gauge readings from international sources.

FAQ
1. How do I manually convert kg/cm² to PSI?
Multiply the pressure value in kg/cm² by 14.22334. For example, 5 kg/cm² × 14.22334 = 71.1167 psi.
2. What is the reverse formula for converting PSI to kg/cm²?
Divide the psi value by 14.22334. For instance, 100 psi ÷ 14.22334 ≈ 7.031 kg/cm².
3. Where does the number 14.22334 come from?
It is derived from the relationship between kilogram-force and pound-force (1 kgf ≈ 2.20462 lb) and between square centimeter and square inch (1 cm² ≈ 0.1550 in²), resulting in the constant multiplier used for both conversion directions.
4. Can I use this converter on a mobile phone or tablet?
Yes, the converter runs in any standard web browser and works on desktop computers, tablets, and smartphones without needing to download or install any software.
