Magnetic Declination – Magnetic Variation

Web(1) Look at the declination diagram and determine the direction between the line representing grid north and the line representing magnetic north. (2) Put your finger on the grid north line, now move it to the magnetic north line. If you moved left you should add the angle between grid and magnetic; if you moved right, you should subtract. WebConvert a grid azimuth to a magnetic azimuth. • To convert grid azimuth to magnetic azimuth, take your grid azimuth (the one on you find on your map) and subtract the G-M angle if the G-M angle is easterly. • If the G-M angle is westerly, then you will add the grid azimuth by the G-M angle.
