Boxing the compass was a navigational practice used by traditional mariners to travel at sea, which used all 32 points of the compass. A bearing of South 70 degrees West would be the same as 250 degrees on a normal 360 degree compass (180 degrees for South plus 70 degrees). Cardinal directions are the four main points of a compass: north, south, east, and west which are also known by the first letters: N, S, E, and W. These four directions are also known as cardinal points. Each of the 96 fractional points can be named in two ways, depending on which of the two adjoining whole points is used, for example, N3/4E is equivalent to NbE1/4N. Magnetic declination is expressed in degrees east or west. Each direction is 11.25 (360 / 32) degrees farther than the previous. This applies for every adjacent pair of directions, so the midpoint between East (90) and South (180) is Southeast at 135 degrees. Convert a Point of the Compass to Degrees.

Hopefully enough to qualify? Multiply the decimal part by 60. This is air damped and comes with a pointer locking mechanism. Different compass roses (4, 8, 16, 32, 128-wind compass roses) are supported. And while it is easier to use our advancements in technology, we should also not forget the methods used by our seafaring descendants. Traditionally, wind direction is reported as one of eight compass point (N, NE, E, SE . For example, N (north) is 0 degrees, NbE (north by east) is 11.25 degrees, NNE (north-northeast) is 22.5 degrees, etc. The Mariners Compass of 360 degrees is divided into 32 points.

Read your orientation, followed by the nearest cardinal direction, followed by the nearest of the eight directions. If you want to find the accuracy of a cardinal direction, the method of seeing the magnetic needle at 0 degrees is a good way. For example, in Florida, magnetic north currently lies around 5 degrees west of true north, so the Sunshine State has a magnetic declination of -5. It used the 32 "points of the compass" shown in this compass rose diagram. You may have wondered where they . @WallyWest Hmm, this one allows arrays, has different capitalization, and has no "between," but I didn't notice that (possibly because of the interesting title :P).

If your compass is marked in gradations -- for instance, marked off in 20-degree regions -- then it will be easier to read but less precise. After that starting from 90 degrees count the number of degrees that your line that links the two points is away from 90 degrees (our zero line - see the compass rose at the top of this page). For this reason, there is 11.25 between each point of the compass. Naming all 32 points on the rose is called boxing the compass. If the North magnetic needle is not at 0 degrees, it is certain that the compass you have is damaged so it cannot show the right direction.
