2010 Current Year Last known correct declination year = 37 Total 37 X.05 (mills conversion) = 1.85 Degrees 3.08 Last known correct declination (variation) = 4.93 Degrees grid to magnetic West ● MUNDARING WEIR Latitude: 31° 56' 60" S Longitude: 116° 10' 0" E Magnetic declination: 1° 25' WEST( degrees) Declination is NEGATIVE

GMA GRID – MAGNETIC - ACTUAL

Grid Magnetic Actual Easterly Variation 4 o 50 o Magnetic baring of 50 degrees converted to grid baring = 54 degrees (grid) Grid baring of 50 degrees converted to magnetic baring 50 – 4 = 46 degrees (magnetic)

Grid Magnetic Actual Westerly Variation 15 o 50 o Magnetic baring of 50 degrees converted to grid baring = 65 degrees (grid) Grid baring of 50 degrees converted to magnetic baring = 65 degrees (magnetic)
