Where can I find a conversion of Rockwell Hardness "M" Scale to Barcol Hardness?

Thanks, I already saw that URL and it doesn't provide a conversion between Rockwell M to Barcol. I have even been trying to find rockwell M to shore D and then shore D to Barcol but I haven't had much success.

You have to forgive me as I do not know
what Rockwell M scale is. I have a feeling
that Barcol scale is well below the Rockwell
Scales, but not certain. Does the M mean
micro? I have seen M used for the Moh scale.
I do see that one of the graphs shows
Rockwell M verses Shore D scale ie see
figure 6.

Yes I have seen that figure. I am still trying to find the correlation between shore D to Barcol.
