From a westerly magnetic azimuth to a grid WebThis is called "easterly declination". At any point east of the zero declination line, the compass needle will point west of True North. This is called "westerly declination". In North America, magnetic declination varies from 30° east in Alaska to 30° west in Labrador.
WebFor easterly declinations, a negative sign is shown. For western declinations, a plus sign is shown. These signs indicate how to convert from the true bearing shown on the map to the compass bearing that you would need to follow. For example, in Boulder, Colorado, in 2004, the declination is 10.4 deg East.
