RADIANS function

RADIANS function is a useful tool in Microsoft Excel that helps you convert angles from degrees to radians. This can be handy when working with trigonometric calculations or when your data is in radians, and you need to make it consistent with other angle measurements.




angleThe angle in degrees that you want to convert to radians.

How to use

To use the RADIANS function in Excel, follow these steps:

  1. Click on the cell where you want to display the result of the conversion.
  2. Type the formula: =RADIANS(angle)
  3. Replace “angle” with the actual angle you want to convert from degrees to radians.
  4. Press Enter, and the cell will display the angle in radians.


Let’s look at some examples to see how the RADIANS function works:

Example 1: Converting 45 degrees to radians.

The result will be approximately 0.7854 radians.

Example 2: Converting 90 degrees to radians.

The result will be approximately 1.5708 radians.

Example 3: Converting an angle stored in cell A1 to radians.

If cell A1 contains 30, the result will be approximately 0.5236 radians.

Remember that Excel uses radians as the default unit for trigonometric functions. If you need to work with degrees, you may need to use the RADIANS function to convert them to radians before performing calculations.
