Definition of Kgf/cm2
Kilogram-force per Square Centimeter: Technical Metric Unit
The kilogram-force per square centimeter (kgf/cm² or kg/cm²) is a gravitational metric unit of pressure. It represents the pressure exerted by a force of one kilogram-force applied to an area of one square centimeter. This unit is commonly used in older metric equipment, particularly in automotive (tire pressure), industrial machinery, and some Asian countries.
Conversions to Other Units of Measurement:
- Pascal (Pa): 1 kgf/cm² equals exactly 98,066.5 pascals. This conversion factor comes from the standard acceleration of gravity.
- Bar: 1 kgf/cm² equals approximately 0.980665 bar. They are nearly equivalent, which made the bar popular as a replacement.
- PSI: 1 kgf/cm² equals approximately 14.2233 psi. This conversion is important for automotive and industrial applications.
- Atmosphere (atm): 1 kgf/cm² equals approximately 0.967841 atm. This is very close to one atmosphere.
- Kilopascal (kPa): 1 kgf/cm² equals exactly 98.0665 kPa. For example, 2 kgf/cm² equals 196.133 kPa.
While being phased out in favor of SI units, kgf/cm² remains in use in many existing industrial systems and pressure gauges.

Definition of Psi
PSI: Pound per Square Inch
PSI (pound-force per square inch or lbf/in²) is a unit of pressure commonly used in the United States and other countries that use imperial units. It measures the force in pounds applied to an area of one square inch. PSI is widely used for tire pressure, hydraulic systems, pneumatic tools, and various industrial applications.
Conversions to Other Units of Measurement:
- Bar: 1 psi equals approximately 0.0689476 bar. This conversion is essential for international equipment specifications. For example, 30 psi equals approximately 2.07 bar.
- Pascal (Pa): 1 psi equals approximately 6,894.76 pascals. This conversion connects imperial to SI units. For example, 14.7 psi (approximately 1 atm) equals about 101,325 Pa.
- Kilopascal (kPa): 1 psi equals approximately 6.89476 kPa. This is frequently used in automotive and engineering contexts. For example, a tire pressure of 32 psi equals approximately 220.6 kPa.
- Atmosphere (atm): 1 psi equals approximately 0.068046 atm. Standard atmospheric pressure (1 atm) equals approximately 14.696 psi.
- Kilogram-force per square centimeter (kgf/cm²): 1 psi equals approximately 0.070307 kgf/cm². This conversion is used in older metric equipment.
PSI remains the dominant pressure unit in North America for everyday applications like tire inflation, air compressors, and blood pressure (though medical uses mmHg).

About the Kgf/cm2
Facts & Uses
- Kilogram-force per square centimeter — a non-SI metric unit defined as 1 kgf/cm² = 98,066.5 Pa exactly (close to but not equal to 1 bar or 1 atm).
- Common in tire pressure gauges in older European, Japanese, and Latin American specifications. Still printed on many tire sidewalls and gauges.
- Used in industrial machinery, boiler ratings, and pressure vessel specifications — especially in pre-1980 documentation that survives in maintenance manuals.
- Convenient because it gives round numbers for everyday pressures: car tire ≈ 2 kgf/cm², household water ≈ 3-4 kgf/cm², industrial air ≈ 6-8 kgf/cm².
Curiosities
- The kgf/cm² is sometimes called the "technical atmosphere" (at), distinct from the standard atmosphere (atm = 101,325 Pa).
- 1 kgf/cm² ≈ 0.9678 atm ≈ 0.9807 bar — close enough that engineers often treat them as equivalent in informal calculations.
- The SI replaced kgf/cm² with the bar and pascal in international standards starting in the 1970s, but legacy use persists in many trades.
- Approximate equivalents: 1 kgf/cm² ≈ 14.22 psi ≈ 0.981 bar ≈ 98.07 kPa.

About the Psi
Facts & Uses
- Pounds per square inch — the dominant pressure unit in US and UK engineering. 1 psi = 6894.757 Pa (derived from 1 lbf and 1 in², not exact in SI).
- Standard for US tire pressure (cars 30-35 psi, bicycles 60-100 psi), plumbing (40-80 psi household water), and compressed air tools.
- Common in gauge measurements: psig (gauge, relative to atmospheric) vs psia (absolute, including atmospheric pressure of 14.7 psi).
- Used in scuba diving in the US (3000 psi tanks), oil & gas industry, boiler ratings, and welding cylinders.
Curiosities
- 1 atm = 14.696 psi exactly — the value taught in US chemistry classes as the standard reference for sea-level pressure.
- The pressure inside a champagne bottle is 5-6 bar (75-90 psi) — about three times typical car tire pressure, which is why corks fly with such force.
- The deepest point in the Mariana Trench exerts about 16,000 psi (110 MPa) — over 1000 atmospheres.
- Approximate equivalents: 14.7 psi ≈ 1 atm ≈ 1.01 bar ≈ 101.3 kPa ≈ 760 mmHg.
