Convert Radians to Degrees

Convert angles from radians to degrees using the math:rad2deg() function

Query
logscale
myvalue := 3.14159
        | math:rad2deg(myvalue, as=degrees)
Introduction

Common radian to degree conversions:

  • π radians = 180 degrees

  • π/2 radians = 90 degrees

  • π/4 radians = 45 degrees

  • π/6 radians = 30 degrees

In this example, the math:rad2deg() function is used to convert the radian value 3.14159 to degrees.

Step-by-Step

  1. Starting with the source repository events.

  2. logscale
    myvalue := 3.14159

    Assigns approximately π radians to a field named myvalue. This value should convert to approximately 180 degrees.

  3. logscale
    | math:rad2deg(myvalue, as=degrees)

    Converts the radian value in the myvalue field to degrees and returns the result in a field named degrees.

  4. Event Result set.

Summary and Results

The query converts an angle measurement from radians to degrees. This conversion is essential when working with trigonometric functions, as many mathematical operations use radians while human-readable angles are typically expressed in degrees.

This query is useful for converting angular measurements, working with geometric calculations, or transforming mathematical results into more readable formats. The conversion factor used is 180/π (approximately 57.2958 degrees per radian).

Sample output from the incoming example data:

degrees
180.000

The result shows that π radians (approximately 3.14159) converts to 180 degrees, demonstrating the standard conversion between radians and degrees.
