How to Convert Angles From Degrees to Radians in Excel
If you are working with angles in Excel, you may need to convert them from degrees to radians or vice versa. Converting angles from degrees to radians is a common task in many mathematical calculations, including trigonometry, calculus, and physics. Fortunately, Excel makes it easy to convert angles from degrees to radians using a simple formula. In this article, we will discuss how to convert angles from degrees to radians in Excel.
What are degrees and radians?
Before we dive into the Excel formulas, let us first understand what degrees and radians are. Degrees are a measurement of the angle, where one complete revolution consists of 360 degrees. Radians, on the other hand, are a different way to measure the angle, and one complete revolution is equal to 2π (two times Pi) radians.
Converting angles from degrees to radians in Excel
To convert an angle from degrees to radians in Excel, you need to use the RADIANS function. This function converts an angle from degrees to radians by multiplying it by Pi (π/180). Here is the syntax for the RADIANS function:
=RADIANS(angle)
The angle is the value you want to convert from degrees to radians. Let us take a simple example to illustrate this formula. Suppose you have an angle of 45 degrees that you want to convert to radians. The formula would be:
=RADIANS(45)
The result will be:
0.785398163
This means that 45 degrees is equal to approximately 0.785 radians.
Converting angles from radians to degrees in Excel
If you want to convert an angle from radians to degrees in Excel, you can use the DEGREES function. This function converts an angle from radians to degrees by multiplying it by 180/π. Here is the syntax for the DEGREES function:
=DEGREES(angle)
The angle is the value you want to convert from radians to degrees. Let us take a simple example to illustrate this formula. Suppose you have an angle of 1.5 radians that you want to convert to degrees. The formula would be:
=DEGREES(1.5)
The result will be:
85.94366927
This means that 1.5 radians is equal to approximately 85.9 degrees.
In conclusion, converting angles from degrees to radians and vice versa is a simple task in Excel. You can use the RADIANS function to convert angles from degrees to radians, and the DEGREES function to convert angles from radians to degrees. Remember to use radians when dealing with calculus, physics, and trigonometry calculations, and use degrees when dealing with geometry calculations
