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 Bar
Bar: A Widely Used Pressure Unit
The bar is a metric unit of pressure defined as exactly 100,000 pascals (100 kPa). While not an SI unit, it is accepted for use with the SI and is widely used in meteorology, engineering, and industry. The bar is particularly convenient because standard atmospheric pressure (1 atm) is approximately equal to 1 bar (actually 1.01325 bar).
Conversions to Other Units of Measurement:
- Pascal (Pa): 1 bar equals exactly 100,000 pascals. This conversion is used when working with SI units. For example, 2 bar equals 200,000 Pa or 200 kPa.
- PSI (Pound per Square Inch): 1 bar equals approximately 14.5038 psi. This is one of the most common conversions in industrial applications. For example, a tire pressure of 2.5 bar equals approximately 36.3 psi.
- Atmosphere (atm): 1 bar equals approximately 0.986923 atm. Standard atmospheric pressure (1 atm) equals 1.01325 bar.
- Kilopascal (kPa): 1 bar equals exactly 100 kPa. This conversion is straightforward and commonly used in engineering. For example, 3.5 bar equals 350 kPa.
- Millibar (mbar): 1 bar equals exactly 1,000 millibar. Millibars are commonly used in meteorology for atmospheric pressure measurements.
The bar is valued for its practical convenience, being close to atmospheric pressure while having a simple relationship with SI units.

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 Bar
Facts & Uses
- 1 bar = 100,000 Pa = 100 kPa exactly. Defined in 1909 by Vilhelm Bjerknes as a convenient meteorological unit close to atmospheric pressure.
- Standard for tire pressure in many European countries (~2.0-2.5 bar for cars), compressed air systems, and water pressure.
- Common in diving (1 bar per 10 m of seawater depth), brewing (espresso extraction at 9 bar), and scuba tanks (200-300 bar fill pressure).
- Weather use: millibars (mbar) = 1/1000 bar = hectopascals (hPa). 1013 mbar = standard sea level pressure.
Curiosities
- The bar is not part of the SI, but is accepted for use with the SI system because of its convenient scale and historical adoption in meteorology.
- The name comes from the Greek "baros" (βάρος) meaning "weight" — also the root of "barometer" and "barometric pressure".
- Atmospheric pressure varies from a record low of 870 mbar (Typhoon Tip, 1979) to a record high of 1085 mbar (Mongolia, 2001).
- Approximate equivalents: 1 bar = 14.504 psi = 0.987 atm = 750 mmHg.
