The RADIANS function in Excel is used to convert degrees into radians. This function is particularly useful in trigonometric calculations where angles need to be in radians instead of degrees.
Here’s how to use the RADIANS function:
Syntax
RADIANS(angle)
- angle: This is the angle in degrees that you want to convert to radians.
Example
If you want to convert 180 degrees to radians:
=RADIANS(180)
- Click on a cell where you want the output (e.g., cell A1).
- Enter the formula:
- Press Enter.
The result will be approximately 3.141593, which is π, as 180 degrees is equivalent to π radians.
Additional Tips
- You can reference other cells in the formula where the degree value is stored. For example, if cell B1 contains the degree value, you can use `=RADIANS(B1)`.
- The RADIANS function is useful in conjunction with other trigonometric functions like SIN, COS, and TAN, which typically require the angle to be in radians.
That’s it! By using the RADIANS function, you can easily perform conversions from degrees to radians directly within Excel.
