You mean your magnetic heading. You have your actual heading. You
need a table of magnetic variations and interprolate from the table
based on your location as there is no mathmatical model that will
provide this information reliably.


(Sorry to reply here your post was cancelled).

Yes i do mean the magnetic heading.
Sorry I was not clear.

Where can i get a table to compute my magnetic heading?

You might take a look at the Canadian Geological Survey
Geomagnetism website:

After all, the North magnetic pole is in Canada ;-)
