The RADIANS function in Google Sheets is a valuable tool used to convert angles from degrees to radians, a necessary step in various mathematical, engineering, and scientific calculations. Radians provide a direct and efficient way to express angles when dealing with trigonometric functions and calculations. This function ensures that users can seamlessly convert degrees into radians with ease.

Syntax

RADIANS(degrees)

• degrees: The angle value measured in degrees that you want to convert to radians.

Example #1

RADIANS(180)

This function call converts 180 degrees to radians. The result is approximately 3.14159.

Example #2

RADIANS(90)

Here, converting 90 degrees to radians gives a result of approximately 1.5708, which is equivalent to π/2.

Example #3

RADIANS(360)

In this instance, 360 degrees converted to radians results in 6.28319, representing a full circle (2π).

Error handling

• VALUE!: This error occurs when the input is not a valid numeric value, indicating that a non-numeric value has been provided for the degrees parameter.
• REF!: This error happens if the formula references a cell that does not exist or contains an invalid reference.

Conclusion

The RADIANS function is essential for professionals and students alike who require angle conversions for calculations involving trigonometric functions. Understanding how to use this function effectively simplifies tasks and enhances computational precision, especially in fields such as physics, engineering, and mathematics.
