WebHow do I correct my compass to the true bearing? You can compute the true bearing from a magnetic bearing by adding the magnetic declination to the magnetic bearing. This works as long as you follow the convention that degrees west are negative (i.e. a magnetic declination of 10-degrees west is -10 and bearing of 45-degrees west is -45).
