# How To Use RADIANS function in Excel with Guides

### How To Use RADIANS function in Excel?

The RADIANS function in Excel is used to convert degrees to radians. It takes an angle in degrees as an argument and returns the equivalent angle in radians.

### Description

RADIANS Function in Excel is a mathematical formula that helps to calculate the angle in radians based on the angle measured in degrees. It is a useful tool to use when dealing with angles and lengths in geometry problems. It can also be used to convert degrees to radians and vice versa.

To use the function enter the angle measure in degrees. This will then return the angle measure in radians. The function converts angles in degrees to angles in radians. This is done by multiplying the angle measure in degrees by pi divided by 180.

For example, if the angle measured in degrees is 45, the corresponding angle measured in radians is 0.7854. The Radians Function is also used for geometry problems. Angles are often measured in radians as opposed to degrees, making the function a very useful tool. It is used to convert the angle measure in degrees to the angle measure in radians, allowing the user to solve the problem more easily.

The Radians Formula is useful in converting the circumference of a circle to its radius. This is done by multiplying the circumference by the inverse of pi divided by 180. This is then used to calculate the radius of the circle from the circumference.

### Syntax 1. Open a blank Excel worksheet.
2. In an empty cell, enter the degree value you want to convert to radians.
3. In the cell to the right, enter the formula =RADIANS(A1) where A1 is the cell containing the degree value.
4. Press Enter on your keyboard to evaluate the formula.
5. The result in the cell will be the radian value.

What are radians and how are they different from degrees?

Radians are a unit of measurement used to express angles in trigonometry. Unlike degrees, which divide a circle into 360 parts, radians divide a circle into 2π parts. They are often used in mathematical calculations involving trigonometric functions.

How does the RADIANS formula compare to the DEGREES function in Excel?

The RADIANS function in Excel is used to convert degrees into radians. On the other hand, the DEGREES function is used to convert radians into degrees. So, while the RADIANS function takes a value in degrees as its argument and returns the equivalent value in radians, the DEGREES function takes a value in radians and returns the equivalent value in degrees.
