Calculator Description
Hardness Calculator v1
The hardness conversion calculator for Vickers, Brinell, Shore and Rockwell hardness sub-scales

Hardness Converter

Subject

A material’s hardness is its ability to resist deformation, the measurement method of which varies with environment (laboratory or site) and/or required range & accuracy. Despite the different measurement methods, most scales can be successfully used to measure the hardness of the same or similar materials and therefore correlate one with another.

CalQlata has devised a series of formulas that provide accurate and consistent conversions between the various measurement scales, a detailed description of which is presented in our Hardness Conversion page.

Calculator

The hardness calculator converts between various Vickers, Brinell, Shore and Rockwell hardness sub-scales. You enter a value for any scale you wish and Hardness will simultaneously convert it into all the others.

Despite the fact that most hardness conversions have a limited viability range, Hardness allows you to convert into any scale you like as long as the calculation is possible. However, where values entered for any given value fall outside CalQlata’s recommended range a warning will be displayed to notify you of the recommended range for the scale concerned.
