RADIANS

How to Use the Power BI DAX function RADIANS

What is the RADIANS function?

The RADIANS function in Power BI is a mathematical function that converts degrees to radians. It takes an angle in degrees as input and returns the angle in radians. The formula to convert degrees to radians is:

Radians = Degrees x (PI/180)

Where PI is a mathematical constant, approximately equal to 3.14159265.

How to use the RADIANS function in Power BI?

To use the RADIANS function in Power BI, follow these simple steps:

1. Open Power BI and create a new report.

2. Add a table or a visual to your report that contains the angle in degrees you want to convert to radians.

3. Add a new calculated column to your table. To do this, right-click on your table and select “New column”.

4. In the formula bar, enter the following formula:


Radians = RADIANS(Table[Degrees])


Replace "Table" with the name of your table and "Degrees" with the name of the column that contains the angle in degrees.

5. Press Enter to apply the formula.

6. You should now see a new column in your table that contains the angle in radians.

Why is it important to use the RADIANS function?

Radians are a more natural unit of measurement for angles in mathematics and science than degrees. By converting degrees to radians, you can perform more complex calculations using trigonometric functions such as sine, cosine, and tangent. These functions require angles to be expressed in radians, so converting degrees to radians is an essential step in many calculations.

In addition, Power BI uses radians as the default unit of measurement for angles in some visualizations. This means that if you want to use a visual that requires angles to be expressed in radians, you will need to convert your data from degrees to radians using the RADIANS function.

The RADIANS function in Power BI is a powerful tool that allows you to convert angles from degrees to radians. By using this function, you can perform more complex calculations and use visuals that require angles to be expressed in radians. We hope that this article has helped you understand how to use the RADIANS function in Power BI and why it is important to use this function.
