To convert a magnetic azimuth to a grid azimuth, add the GM angle. (You and @iant have already hit on that concept.) Support (indirect, direct, and medical) and communications. I've been told to add 1.49 deg to the True North measures to convert them to Grid North measures. MISCELLANEOUS - Converting azimuths - Army Education Benefits Blog Grid bearing of survey line is clockwise angle from grid north and similarly clockwise angle from magnetic north is Magnetic bearing. Check commo and establish emergency signals. . Since magnetic variation if an f(location) - it is the same for all magnetic headings on the same location - you can use this variation for calculations with user input. If you plot your grid azimuth on a map and it reads (for example), 180 degrees (GAZ), and you know your local declination is 15 degrees East, and you wish to convert your GAZ to a MAZ, simply subtract the Declination of 15 degrees and you'll have a 165 MAZ, or 'magnetic' azimuth that you can use with your compass. Magnetic tools determine azimuth relative to earths magnetic field and as such can be affected by magnetic interference from magnetic rocks and metallic objects such as drill strings. container.style.maxHeight = container.style.minHeight + 'px'; Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0?

Using an Ohm Meter to test for bonding of a subpanel. Direction from the observer to the target. A bearing (or azimuth) is a clockwise angle from (some) North to some direction of interest. ins.id = slotId + '-asloaded'; How many degrees off course is she? If you are, as you say, "going from True to Grid (in a counterclockwise direction)" and if you are converting True bearings to Grid bearings then you must add the value 1.49. The obvious drawback is that you have to have fresh location/heading data. This is your magnetic azimuth, the direction you want to walk according to your compass. I should have said that the declination is 13.113 deg. The azimuth, 260, is more than 180, so subtract 180 from the azimuth. PDF Direction B181996 Student Handout "25 INFANTRYMEN IN OPEN.
