Excel's RADIANS Function

Since Excel's, trig functions use radians, we often need a way of converting angles measured in degrees to radians. The RADIANS function, one of Excel's math functions, does just that.

The syntax for the RADIANS function is:

= RADIANS ( Angle )

Angle - the angle in degrees to be converted to radians.

Example: Using Excel's RADIANS Function

For help with this example, see the image above.

1. Enter the following data into cell D1: 34
   
   
2. Click on cell E1 in the spreadsheet - this is where the function will be located.
   
   
3. Click on the Formulas tab of the ribbon menu.
   
   
4. Choose Math & Trig from the ribbon to open the function drop down list.
   
   
5. Click on RADIANS in the list to bring up the function's dialog box.
   
   
6. In the dialog box, click on the Angle line.
   
   
7. Click on cell D1 in the spreadsheet.
   
   
8. Click OK.
   
   
9. The answer 0.593412 should appear in cell E1.
   
   
10. When you click on cell E1 the complete function = RADIANS ( D1 ) appears in the formula bar above the worksheet.
