West-Southwest

Compass points

North indicates 0° (0 degrees). 90 degrees is East, south is 180°, and west is 270°.

Read your orientation, followed by the nearest cardinal direction, followed by the nearest of the eight directions. For example, say your orientation is 230 degrees. The nearest of the eight directions is Southwest at 225 degrees, which is five degrees lower, and the nearest cardinal direction is West.

DIRECTION (THINKING IN CIRCLES)

A true bearing expresses the direction in terms of the angle made with North, the angle always being drawn clockwise. For example: In the diagram at right the angle drawn clockwise from North is 35°.

Wind direction is typically reported in degrees, and describes the direction from which the wind emanates. A direction of 0 degrees is due North on a compass, and 180 degrees is due South. A direction of 270 degrees would indicate a wind blowing in from the west.

one of the four main points of a compass: north, east, south, west. symbol indicating the cardinal directions (N, S, E, W).

A compass rose with both ordinal and cardinal directions will have eight points: N, NE, E, SE, S, SW, W, and NW.

To the left is West and to the right is East. …

The eight half-winds are the direction points obtained by bisecting the angles between the principal winds. The half-winds are north-northeast (NNE), east-northeast (ENE), east-southeast (ESE), south-southeast (SSE), south-southwest (SSW), west-southwest (WSW), west-northwest (WNW) and north-northwest (NNW).

360 degrees

Intercardinal directions Northeast (NE), 45°, halfway between north and east, is the opposite of southwest. Southeast (SE), 135°, halfway between south and east, is the opposite of northwest.

North = 0 and 360 degrees, east = 90 degrees, south = 180 degrees and west = 270 degrees. The inter-cardinal points lie midway between these points: north-east = 45 degrees, south-east = 135 degrees, south-west = 225 degrees and north-west = 315 degrees.

Degaussing a vessel will cause significant deviation to the magnetic compass. The compass is compensated for degaussing by energising coils around the binnacle to create fields equal and opposite to those created by the degaussing coils.

A binnacle is the housing for a ship’s compass. The idea behind a binnacle is to counter the magnetic deviation caused by the ship being made of iron so that the compass can point to magnetic north. Metals that were used to construct binnacles were required to be non-ferrous (containing no iron) such as brass.

Re: Why are the Balls Red & Green & What is their Purpose? Navigators Balls: The Iron balls attached to either side of the main Compass to help counter the ships magnetic deviation. The Port one was often painted red and the Starboard one green. Also known as Lord Kelvin’s balls.

compasses are usually mounted in binnacles, cylindrical pedestals with provision for illuminating the compass face from below. Each binnacle contains specially placed magnets and pieces of steel that cancel the magnetic effects of the metal of the ship.

SW = Southwest (214-236 degrees) WSW = West-Southwest (237-258 degrees) W = West (259-281 degrees) WNW = West-Northwest (282-303 degrees)

Compasses have four cardinal points: north (N), east (E), south (S), and west (W). Some compasses also display 360 marks called degrees that can be used instead of or in addition to the needle which always points north. North indicates 0° (0 degrees). 90 degrees is East, south is 180°, and west is 270°.

Since the rotation is 90 degrees, you will rotating the point in a clockwise direction.

There is 360 degrees on the dial. North is 0 or 360 degrees and south is 180 degrees. East is 90 degrees and west is 270 degrees. There is a magnetic needle that always points to the magnetic north pole and is usually painted red on the northern pointing end.

The four cardinal directions correspond to the following degrees of a compass: North (N): 0° = 360° East (E): 90° South (S): 180° West (W): 270°

Mil to Degree Conversion Table

Mils are very useful if communicating with somebody who is also using that system on a piece of equipment that IS capable of that level of accuracy (i.e. artillery), but in terms of general map-and-compass, orienteering and outdoor use there is no advantage in accuracy between Mils and Degrees.

Since there IS a need for more precise directions, the circle of a compass face is split into 360 marks called degrees. For rough directions, go ahead and use North or NorthWest. But, for finding your way or locating destinations in the wild, use degrees as you’ll see in a bit.

A full circle is 360 degrees because the Babylonians used the sexagesimal system. It also represents the number of days a year and also because 360 is highly composite.

Since north is zero(0) degrees, true north would be what appears on this compass as 15 degrees (half way between 0 and 30 degrees). If however, you are in a region with a 15 degree east declination (say somewhere on the West coast of US) the needle is actually pointing 15 degrees further east than true north.

In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn).
