Magnetic Azimuth To Grid Azimuth Calculator


Calculating magnetic azimuth to grid azimuth is essential for navigation and orientation in various fields such as aviation, marine, and land navigation. This article presents a practical and efficient calculator to perform this conversion effortlessly.

How to Use

To use the magnetic azimuth to grid azimuth calculator, simply input the magnetic azimuth value and the magnetic declination. Click on the “Calculate” button, and the calculator will provide you with the corresponding grid azimuth.


The formula used for converting magnetic azimuth to grid azimuth is as follows:

Grid Azimuth=Magnetic Azimuth + Magnetic Declination

Example Solve

Suppose we have a magnetic azimuth of 120∘120∘ and a magnetic declination of −10∘−10∘. Using the formula mentioned above:

Grid Azimuth=120∘+(−10∘)

Grid Azimuth=110∘

So, the grid azimuth would be 110∘.


Q: What is magnetic declination?
A: Magnetic declination is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points) and true north.

Q: Why is it important to convert magnetic azimuth to grid azimuth?
A: Converting magnetic azimuth to grid azimuth is crucial for accurate navigation, especially in areas where there is a significant difference between magnetic north and true north.

Q: Can this calculator handle negative values for magnetic declination?
A: Yes, the calculator can handle negative values for magnetic declination. Simply input the negative value as appropriate.


Navigational accuracy is paramount in various industries, and converting magnetic azimuth to grid azimuth is an essential aspect of this process. By utilizing the provided calculator, users can efficiently perform this conversion, enhancing their navigation precision.
