# Magnetic Declination Formula

Magnetic Declination is also referred as the magnetic variation.Magnetic Declination is represented in the Greek word.

$\delta = Magnetic\,Declination$

Magnetic Declination is associated with the year, longitude and latitude of a given location.

## Calculation Of Magnetic Declination Using A Calculator

T = M + V

M = C + D

T = C + V + D (which is a general equation relating compass and true bearings)

Where,

C = Compass Bearing

M = Magnetic Bearing

T = True Bearing

V = Variation

D = Compass Deviation
