About this calculator
Overview
The Vickers hardness test uses a diamond indenter in the form of a square-based pyramid to measure the hardness of materials. It is applicable to a wide range of materials and loads.

Pro Tips
Formula: HV ≈ 1.8544 * F / d²
F is the load in kgf (kilogram-force).
d is the average length of the diagonals in mm.
Ensure 'd' is in mm for this formula constant (1.8544).

Fun Facts
"The Vickers test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd."
"Since the indenter is diamond (the hardest known material), it can test ceramics and hardened metals."
"This test is often known as a 'microhardness' test when low loads are used."
