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

Included Angle when Bearings are Measured in Same Side of Different Meridian

LaTeX 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

LaTeX Go Included Angle when Bearings are in Opposite Side = Back Bearing of Previous Line+Fore Bearing of Previous Line

Included Angle from Two Lines

LaTeX Go Included Angle = Fore Bearing of Previous Line-Back Bearing of Previous Line

Fore Bearing in Whole Circle Bearing System

LaTeX Go Fore Bearing = (Back Bearing-(180*pi/180))

What are the type of Compass?

Surveying compass may be classified as trough compass, tubular compass, prismatic compass and surveyor compass. Of these, the most commonly used compasses for making observations for directions are the surveyor compass and prismatic compass, the latter one preferred being better in performance and accuracy.

How to Calculate Magnetic Declination to East?

Magnetic Declination to East calculator uses Magnetic Declination = True Bearing-Magnetic Bearing to calculate the Magnetic Declination, The Magnetic Declination to East formula is defined as the angle between true north (geographic north) and magnetic north, where the magnetic north is positioned to the east of true north. This angle can be positive or negative and is usually measured in degrees. Magnetic Declination is denoted by MD symbol.
