Use this online calculator to convert pressure from megapascals (MPa) to kilograms-force per square centimetre (kgf/cm²). MPa is an SI-derived unit; kgf/cm² (also written kg/cm², kp/cm², or “technical atmosphere” at) is a legacy metric unit still found on gauges and datasheets. Common abbreviations: MPa, kgf/cm², kg/cm², at.

Definitions & notes

Megapascal (MPa) — SI-derived unit of pressure. 1 MPa = 106 pascals; 1 Pa = 1 N/m². Widely used in engineering because Pa is small. Cross-system reference: 1 MPa ≈ 145.0377 psi (US customary).

Kilogram-force per square centimetre (kgf/cm²) — legacy metric unit (technical atmosphere, symbol at). Using standard gravity gn = 9.80665 m/s², 1 kgf = 9.80665 N and 1 cm² = 1×10−4 m², hence 1 kgf/cm² = 98,066.5 Pa = 98.0665 kPa ≈ 0.980665 bar. Not an SI unit, but still common on equipment.

Conversion formula

From SI: 1 MPa = 1,000,000 Pa (Pascal — Wikipedia). From definition of kilogram-force and area: 1 kgf/cm² = 98,066.5 Pa

Therefore the exact factor is:

kgf/cm² = MPa × (1,000,000 Pa) / (98,066.5 Pa per kgf/cm²) = MPa × 10.1971621298.
