Magnetic Declination to East Solution

STEP 0: Pre-Calculation Summary
Formula Used
Magnetic Declination = True Bearing-Magnetic Bearing
MD = TB-MB
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.
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.
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.
STEP 1: Convert Input(s) to Base Unit
True Bearing: 60 Degree --> 1.0471975511964 Radian (Check conversion here)
Magnetic Bearing: 55 Degree --> 0.959931088596701 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
MD = TB-MB --> 1.0471975511964-0.959931088596701
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 East Formula
