This online calculator converts pressure from kilograms-force per square centimetre (kgf/cm²; also written kg/cm², kp/cm², or technical atmosphere at) to megapascals (MPa). MPa is an SI-derived engineering unit. Common abbreviations: kgf/cm², kg/cm², at; MPa.

Definitions & notes

Kilogram-force per square centimetre (kgf/cm²) — legacy metric pressure unit based on kilogram-force over 1 cm². With standard gravity gn = 9.80665 m/s² and 1 cm² = 1×10−4 m², it follows that 1 kgf/cm² = 98,066.5 Pa = 98.0665 kPa ≈ 0.980665 bar. Not an SI unit, but still common on gauges and datasheets.

Megapascal (MPa) — SI-derived pressure unit. 1 MPa = 106 Pa and 1 Pa = 1 N/m². Convenient for material strengths and hydraulic ratings. Useful cross-system references: 1 MPa = 10 bar; 1 MPa ≈ 145.0377 psi.

Conversion formula

From definitions: 1 kgf = 9.80665 N (standard gravity gn), and 1 cm² = 1×10−4 m², hence 1 kgf/cm² = 98,066.5 Pa. Also 1 MPa = 1,000,000 Pa. Therefore:

MPa = kgf/cm² × (98,066.5 Pa per kgf/cm²) / (1,000,000 Pa per MPa) = kgf/cm² × 0.0980665
