Q4. Convert HRC to BHN.
Ans. 
HRC to BHN conversion is possible using a conversion chart or formula.
• HRC (Rockwell Hardness C) and BHN (Brinell Hardness Number) are two different hardness scales used to measure the hardness of materials.

• To convert HRC to BHN, you can use a conversion chart or the following formula: BHN = (HRC - 13.3) * 10.4.

• For example, if the HRC value is 50, the corresponding BHN value would be (50 - 13.3) * 10.4 = 370.8.
