What is 1 kgf/cm² in MPa (megapascals)?

1 kgf/cm² = 0.1 MPa, and 1 standard atmosphere ≈ 1 kgf/cm².

MPa (megapascal) is the unit of pressure, short for megapascal.1 Pa is the pressure exerted by a force of 1 N uniformly distributed over an area of 1 m².1       megapascal = 1,000,000 pascals, which can also be written as:1 MPa = 1,000,000 Pa.

1 kgf/cm² (commonly called “one kilogram pressure”) refers to a force of 1 kilogram-force applied over an area of 1 square centimeter.The SI unit of pressure is the pascal (Pa), where 1 Pa = 1 N/m², and 1 MPa = 1,000,000 Pa.

Therefore, a force of 1 kgf acting on 1 cm² produces a pressure of 100,000 Pa = 0.1 MPa.1 MPa = 1,000 kPa = 1,000,000 Pa. Note: Pa = N/m².

1 standard atmosphere ≈ 1 kgf/cm²

1 standard atmosphere = 0.1 MPa = 100,000 Pa (N/m²) = 10 N/cm²

1 bar = 1 standard atmosphere

1 kgf/cm² = 0.1 MPa = 1 bar

In engineering practice, the unit kilogram-force is still widely used, leading to the definition of the technical atmosphere.1 kgf = 9.8 N1 technical atmosphere = 1 standard atmosphere ≈ 1 kgf/cm² = 0.1 MPa = 1 bar

Note: The SI unit of pressure is the pascal (Pa).Since the pascal is a very small unit and inconvenient for calculations, MPa is commonly used in industry.For reference, a sunflower seed on a table exerts about 10 Pa.
