To convert a magnetic azimuth to grid azimuth, subtract G-M angle.” If you have a magnetic azimuth of 270 degrees, and the G-M angle is 8 degrees, your grid azimuth will be 262 degrees.

To convert a grid azimuth to a magnetic azimuth you will need to know g-m angle. where would you look for this piece of information?

What is azimuth degrees?
An azimuth is defined as a horizontal angle measured clockwise from a north base line. This north base line could be true north, magnetic north, or grid north. The azimuth is the most common military method to express direction. When using an azimuth, the point from which the azimuth originates is the center of an imaginary circle . This circle is divided into 360 degrees or 6400 mils . NORTH IS 0/360 AZIMUTH EAST IS 90. SOUTH IS 180. WEST IS 270.

What is the back azimuth of 223 degrees?
As the request is for the back azimuth, then what is wanted is the reverse (or inverse) of the azimuth, 223 degrees. In other words, an object moved in the direction of 223 degrees (Southwest relatively), but now the desire is to reverse the travel in order to arrive at the starting point. (That starting point would have to be Northeast relatively.) One does not typically work with directions exceeding 360 degrees nor less than 0 degrees as that range is the range of a compass. Therefore, the back azimuth of 223 degrees, whatever it is, must be between zero and 360 degrees. To determine the back azimuth all that is necessary is the knowledge that 1) the back azimuth is the opposite direction of the azimuth and 2) 180 degrees either added or subtracted will yield the back azimuth, and 3) the correct back azimuth must be in the range of zero to 360 degrees. Given this knowledge and the variable definitions Ab = Back Azimuth and A = Azimuth, Ab = A + 180 or Ab = A - 180 But which equation yields the correct back azimuth? Using knowledge point #3 above, the correct result will be the one that is between zero and 360 degrees. Therefore, Ab = A - 180 = 223 - 180 = 43 degrees is the correct back azimuth. The other choice, Ab = A + 180 = 223 + 180 = 403 degrees, exceeds the range of the compass, so 403 degrees cannot be the correct back azimuth.
Explain hiw you could use a hundredths grid to show how 7 hundredths is different from 7 tenths?
on a hundredths grid 7 hundredths is 7; but seven tenths is 0.7 which is 70 hundredths. So 7 tenths would be 70 on the hundredts grid, separating it from 7 hundredths

How to convert a azmith reading?
If converting from grid to magnetic you subtract, if converting from magnetic to grid you add.

What is grid azimuth?
The azimuthal grid is a coordinate system that stays still while the stars move across it on the sky (the celestial sphere). It measures the altitude above the horizon and the azimuth (position along the horizon) of the celestial object at a particular time, for a particular place.

How do you find magnetic direction?
The angle between the direction your compass points and the direction you're facing is the 'magnetic azimuth'. The angle between the direction to the north pole and the direction you're facing is the 'true azimuth'. They are virtually never the same angle. The difference between them is the 'magnetic declination' or the 'compass declination' in the place where you are at in which.
How many norths are there?
There are three norths: true north, magnetic north and grid north. According to www.ordnancesurvey.co.uk, the three norths are defined as follows: Grid North: the direction of a grid line which is parallel to the central meridian on the National Grid. True North: the direction of a meridian of longitude which converges on the North Pole. Magnetic North: the direction indicated by a magnetic compass. Magnetic North moves slowly with a variable rate and currently is west of Grid North in Great Britain.
What Norths are mostly using in land surveying True North or Magnetic North or Grid North?
magnetic north
