Quick Summary

Use this when you need:

Translate hydraulic setpoints from kg/cm² into psi gauges
Check compressor ratings that mix kg/cm² and kPa
Convert legacy equipment manuals into modern SI units

You’ll get:Pressure

How this is calculated

Formula:

pressure_target = pressure_source

In plain language:

Values are normalized to Pascals using 1 kgf/cm² = 98,066.5 Pa and 1 psi = 6,894.757 Pa, then rescaled into the chosen unit.

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

What these terms mean

Why kg/cm² still shows up

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

Unit	Symbol	Relation to Pa
Pascal	Pa	base
Kilopascal	kPa	$1\\,\\text{kPa} = 1000\\,\\text{Pa}$
Pound per square inch	psi	$1\\,\\text{psi} = 6894.757\\,\\text{Pa}$
Kilogram-force per cm²	kg/cm²	$1\\,\\text{kgf/cm}^2 = 98{,}066.5\\,\\text{Pa}$

Worked examples

1 kg/cm² → psi
$1 \\times 98{,}066.5 / 6{,}894.757 \\approx 14.2233\\,\\text{psi}$ .
100 psi → kg/cm²
$100 \\times 6{,}894.757 / 98{,}066.5 \\approx 7.03\\,\\text{kg/cm}^2$ .
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.
