Magnetic Declination to West Solution

STEP 0: Pre-Calculation Summary
Formula Used
Magnetic Declination = Magnetic Bearing-True Bearing
MD = MB-TB
This formula uses 3 Variables
Variables Used
Magnetic Declination - (Measured in Radian) - Magnetic Declination is the horizontal angle between true north and magnetic north at the time of observation.
Magnetic Bearing - (Measured in Radian) - Magnetic Bearing is the horizontal angle which a line makes with the magnetic meridian is called magnetic bearing. It varies with time.
True Bearing - (Measured in Radian) - True Bearing is the horizontal angle measured clockwise between the true meridian and the line is called true bearing of the line.
STEP 1: Convert Input(s) to Base Unit
Magnetic Bearing: 55 Degree --> 0.959931088596701 Radian (Check conversion here)
True Bearing: 60 Degree --> 1.0471975511964 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
MD = MB-TB --> 0.959931088596701-1.0471975511964
Evaluating ... ...
MD = -0.0872664625996991
STEP 3: Convert Result to Output's Unit
-0.0872664625996991 Radian -->-4.99999999999994 Degree (Check conversion here)
FINAL ANSWER
-4.99999999999994 -5 Degree <-- Magnetic Declination
(Calculation completed in 00.004 seconds)

Included Angle when Bearings are Measured in Same Side of Different Meridian
Go Included Angle = (180*pi/180)-(Fore Bearing of Previous Line+Back Bearing of Previous Line)
Included Angle when Bearings are Measured in Opposite Side of Common Meridian
Go Included Angle = Back Bearing of Previous Line+Fore Bearing of Previous Line
Included Angle from Two Lines
Go Included Angle = Fore Bearing of Previous Line-Back Bearing of Previous Line
Magnetic Bearing given True Bearing with East Declination
Go Magnetic Bearing = True Bearing-Magnetic Declination
Magnetic Bearing given True Bearing with West Declination
Go Magnetic Bearing = True Bearing+Magnetic Declination
True Bearing if Declination is in East
Go True Bearing = Magnetic Bearing+Magnetic Declination
True Bearing if Declination is in West
Go True Bearing = Magnetic Bearing-Magnetic Declination
Magnetic Declination to East
Go Magnetic Declination = True Bearing-Magnetic Bearing
Magnetic Declination to West
Go Magnetic Declination = Magnetic Bearing-True Bearing
Fore Bearing in Whole Circle Bearing System
Go Fore Bearing = (Back Bearing-(180*pi/180))

Magnetic Declination to West Formula

Magnetic Declination = Magnetic Bearing-True Bearing
MD = MB-TB

What are Isogonic and Agonic lines?

Lines joining the places of equal magnetic declination are known as Isogonic lines and those joining the places of zero declination are termed as Agonic lines. On the agonic lines, the magnetic needle defines true as well as magnetic north.
