One complete turn (360°) is equal to 2 π radians, so 180° is equal to π radians, or equivalently, the degree is a mathematical constant: 1° = π ⁄ 180. One turn (corresponding to a cycle or revolution) is equal to 360°.

The difference is known as the drift, and can be determined by the wind triangle. At least seven ways to measure the heading of a vehicle have been described. [ 1 ] Heading is typically based on cardinal directions , so 0° (or 360°) indicates a direction toward true north , 90° true east , 180° true south , and 270° true west .
They can also be derived by using a slightly modified version of the figure for the angle sum identities, both of which are shown here. These identities are summarized in the first two rows of the following table, which also includes sum and difference identities for the other trigonometric functions.

The fractional parts of chord lengths required great accuracy, and were given in sexagesimal notation in two columns in the table: The first column gives an integer multiple of 1 / 60 , in the range 0–59, the second an integer multiple of 1 / 60 2 = 1 / 3600 , also in the range 0–59.
[18] [19] Today, the degree, 1 / 360 of a turn, or the mathematically more convenient radian, 1 / 2 π of a turn (used in the SI system of units) is generally used instead. In the 1970s – 1990s, most scientific calculators offered the gon (gradian), as well as radians and degrees, for their trigonometric functions . [ 23 ]
During the development of the engine, it was found that a 360 degree crank angle was better suited to the use of a single carburettor than a 180 degree crank angle. [ 24 ] Following the trend created by the Triumph Speed Twin, the most common design used by British motorcycle manufacturers until the mid-1970s was a four-stroke straight-twin ...
