Kg Cm to Psi

Pressure Metrology & Technical Atmosphere Standards

The unit kg/cm^2 is also known historically as the Technical Atmosphere (at). It is defined as the pressure exerted by 1 kilogram of mass acting under standard gravity over a 1 cm^2 area.

Primary Pressure Scale Equivalents

• 1 kgf/cm² (at): 14.223343 psi = 0.980665 bar = 98.0665 kPa = 0.967841 atm

• 1 psi: 0.070307 kgf/cm^2 = 0.0689476 bar = 6.89476 kPa

• 1 Bar: = 1.019716 kgf/cm^2 = 14.50377 psi = 100 kPa

• 1 Atmosphere (101.325 kPa): = 1.033227 kgf/cm^2 = 14.69595 psi

Equations

• psi = kgf/cm^2 × 14.2233433

• kgf/cm^2 = psi × 0.07030696

How to Use This Calculator

Enter your Pressure Value to Convert (e.g. 2.20) and Conversion Direction — choose from kg/cm² to psi (kgf/cm² → psi / multiply by 14.223), psi to kg/cm² (psi → kgf/cm² / divide by 14.223). Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Conversion factors used in this calculator:

1 kgf/cm2 = 14.223343307 psi

Worked Example

A Japanese imported vehicle door plaque specifying 2.20 kg/cm² tire inflation pressure converts to exactly 31.3 psi on standard US garage pressure gauges.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
