## How to Convert Angles from Radians to Degrees in Excel

This post will guide you how to convert angles from radians to degrees with a formula in Excel. How do I convert angle between radians to degrees in Excel.

When you want to solve trigonometric expressions like sine, cosine and tangent, you need to use radians to perform these calculations. So if your have a range of list that contain degree values, and you have to convert it to radians for calculation.

You may be have a list of data that contain radian values, and you want to convert it from radians to degrees. You can use a build-in function known as RADIANS function, it can be used to convert degrees to radians. And you can use the DEGREES function to convert radians into degrees in Excel.

## Convert angles from Radians to degrees

Assuming that you have a list of degrees in range B1:B4, and you want to convert those values into radians, just use the following formula:

`=RADIANS(B1)`

Type this formula into a blank cell or the adjacent cell C1, press Enter key to apply this formula. And then drag the AutoFill Handle down to other cells until to C4.

You would see that all degree values has been converted to radian values.

## Convert Angles from Degrees to Radians

If you want to convert radian values to degree values, just use the below formula based on the DEGREES function.

`=DEGREEES(C1)`

Type this formula into a blank cell or the adjacent cell D1, press Enter key to apply this formula. And then drag the AutoFill Handle down to other cells until to D4.

You would see that all radian values have been converted to degree values.

## Excel COS Function

This post will guide you how to use Excel COS function with syntax and examples in Microsoft excel.

### Description

The Excel COS function returns the cosine of a given angle. If you want to supply an angle to COS function in degrees, then you need to multiply the angle by PI()/180. Or you can use the RADIANS function to the angle to radians.

The COS function is a build-in function in Microsoft Excel and it is categorized as a Math and Trigonometry Function.

The COS function is available in Excel 2016, Excel 2013, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000, Excel 2011 for Mac.

### Syntax

The syntax of the COS function is as below:

`= COS(number)`

Where the COS function argument is:

• number –This is a required argument. A number that used to be calculate the cosine of an angle.

Note:

• If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.

### Excel COS Function Examples

The below examples will show you how to use Excel COS Function to return the cosine of an angle.

1# get the cosine of 1.25 radians, enter the following formula in Cell B1.

`=COS(1.25)`

2# get the cosine of 45 degrees, enter the following formula in Cell B2.

`=COS(45*PI()/180)`

3# get the cosine of 30 degrees, enter the following formula in Cell B3.

`=COS(RADIANS(30))`
