2. Radian - Wikipedia

   en.wikipedia.org/wiki/Radian

   A similar calculation using the area of a circular sector θ = 2A/r 2 gives 1 radian as 1 m 2 /m 2 = 1. [10] The key fact is that the radian is a dimensionless unit equal to 1. In SI 2019, the SI radian is defined accordingly as 1 rad = 1. [11] It is a long-established practice in mathematics and across all areas of science to make use of rad ...

3. Turn (angle) - Wikipedia

   en.wikipedia.org/wiki/Turn_(angle)

   The binary degree, also known as the binary radian (or brad), is ⁠ 1 / 256 ⁠ turn. [21] The binary degree is used in computing so that an angle can be represented to the maximum possible precision in a single byte. Other measures of angle used in computing may be based on dividing one whole turn into 2 n equal parts for other values of n. [22]

4. Degree (angle) - Wikipedia

   These considerations outweigh the convenient divisibility of the number 360. 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°.

5. Small-angle approximation - Wikipedia

   en.wikipedia.org/wiki/Small-angle_approximation

   The quantity 206 265 ″ is approximately equal to the number of arcseconds in a circle (1 296 000 ″), divided by 2π, or, the number of arcseconds in 1 radian. The exact formula is = ⁡ (″) and the above approximation follows when tan X is replaced by X.

6. Binary angular measurement - Wikipedia

   The number can also be interpreted as a fraction of a full turn between 0 (inclusive) and 1 (exclusive) represented in binary fixed-point format with a scaling factor of 1/2 n. Multiplying that fraction by 360° or 2π gives the angle in degrees in the range 0 to 360, or in radians , in the range 0 to 2π, respectively.

7. Steradian - Wikipedia

   en.wikipedia.org/wiki/Steradian

   This means that the SI steradian is the number of square radians in a solid angle equal to one square radian, which of course is the number one. It is useful to distinguish between dimensionless quantities of a different kind , such as the radian (in the SI, a ratio of quantities of dimension length), so the symbol sr is used.
