WebRa to Rz. R z M i n = 3.8 × R a 0.95 R z M a x = 14.5 × R a 0.75. Converting between Ra and Rz is not a good engineering practice. It is always recommended to Measure according to the method in which surface roughness is indicated on the drawing. As you can see in the below graphs, the inaccuracy grows in higher R a /R z values. Web* Surface roughness measurements differ with different instruments, labora-tories and operators. There may also be overlap on measurements of surface roughness for both No. 3 and No. 4 finishes.
