How to Convert Megapascal to Kilogram-force per Square Millimetre
- 1 MPa = 0.1019716213 kgf/mm²
- 1 kgf/mm² = 9.80665 MPa
- Example: convert 400 MPa to kgf/mm²: 400 MPa = 400 × 0.1019716213 kgf/mm² = 40.78864852 kgf/mm²
Formula
kgf/mm² = MPa × 0.1019716212978
or kgf/mm² = MPa ÷ 9.80665
Derivation from SI units:
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 MPa = 1000000 Pa ÷ 9806650 Pa per kgf/mm² = 0.1019716212978 kgf/mm²
Both units are defined exactly, so the factor is exact. Megapascal definition: megapascal; Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre.
Worked examples
- A tensile strength of 400 MPa is 40.78864852 kgf/mm².
400 MPa × 0.1019716213 = 40.78864852 kgf/mm² - A 1000 MPa high-strength steel is 101.9716213 kgf/mm².
1000 MPa × 0.1019716213 = 101.9716213 kgf/mm²
