Calculation method
Calculation method
Mean diagonal (mm)
Vickers pyramid convention HV=0.1891×force N/(mean diagonal mm)²; nominal coefficient, test preparation external.
Vickers hardness number (HV)
Vickers pyramid convention HV=0.1891×force N/(mean diagonal mm)²; nominal coefficient, test preparation external.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Vickers pyramid convention HV=0.1891×force N/(mean diagonal mm)²; nominal coefficient, test preparation external. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
