Hi there Hubert,
I don't know the formula off-hand - but I would say be careful if you look
online for conversion factors...
I recently had a confusion between an engineering designer and a company
making bits for us at work, where one specified:-
* Inches of taper of the diameter per foot
* Inches of taper of the radius per foot
...with one giving you twice the taper of the other!
Needless to say the tapered fittings and the holes didn't fit and it took
six weeks for the parts to be remachined (only to find the same two had
mixed up metric fine and course threads for the large diameter bolts
holding the tapered fittings in place!).
Such is life!
Yours,
Rich.
