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 MPa
Megapascal: High-Pressure Applications
The megapascal (MPa) is an SI-derived unit of pressure equal to 1,000,000 pascals (1,000 kPa or 10 bar). It is commonly used in engineering and materials science for measuring high pressures, such as the tensile strength of materials, hydraulic system pressures, and geological pressures. The megapascal provides convenient numbers when dealing with pressures that would be unwieldy in pascals or kilopascals.
Conversions to Other Units of Measurement:
- Bar: 1 megapascal equals exactly 10 bar. This simple relationship makes MPa convenient for high-pressure industrial work. For example, 20 MPa equals 200 bar.
- PSI: 1 megapascal equals approximately 145.038 psi. This conversion is essential for engineering specifications. For example, a steel with 250 MPa yield strength equals approximately 36,260 psi.
- Kilopascal (kPa): 1 megapascal equals exactly 1,000 kPa. For example, 5 MPa equals 5,000 kPa.
- Pascal (Pa): 1 megapascal equals exactly 1,000,000 pascals. This is the fundamental SI relationship.
- Atmosphere (atm): 1 megapascal equals approximately 9.86923 atm. This shows that MPa represents significantly higher pressures than atmospheric.
The megapascal is essential in structural engineering, material science, and any application involving high pressures.

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 MPa
Facts & Uses
- 1 MPa = 1,000,000 Pa = 1 N/mm² exactly — the convenient unit for high pressures and material stresses.
- Standard in materials science for tensile strength: structural steel ≈ 250 MPa yield, high-strength steel 400-700 MPa, carbon fiber 3500+ MPa.
- Used in hydraulic systems (typical hydraulic pressures 10-35 MPa), injection molding, and industrial pressure vessels.
- High-pressure applications: diamond anvil cells reach 100-300 GPa; deep ocean trenches around 100 MPa at the Mariana Trench.
Curiosities
- Concrete compressive strength is typically expressed in MPa: 25 MPa for residential, 40+ MPa for high-rise buildings, 100+ MPa for ultra-high-performance concrete.
- The Earth's pressure at the core-mantle boundary reaches about 136 GPa = 136,000 MPa — beyond what can be sustained at the surface in any container.
- 1 MPa is approximately the pressure under a 1 cm column of mercury per square millimeter, or about 145 psi.
- Approximate equivalents: 1 MPa = 145 psi = 9.87 atm = 10 bar.
