Key Takeaway:
- Understanding the difference between radians and degrees is crucial for accurately measuring angles. Radians are based on the radius of a circle, while degrees are based on dividing a circle into 360 equal parts.
- The conversion formula for radians to degrees is simple – multiply the radian value by 180/π. For example, to convert 2 radians to degrees, multiply 2 by 180/π to get 114.59 degrees.
- Excel has a built-in function for converting radians to degrees, which is “DEGREES”. Simply input the radian value in Excel and use the function “=DEGREES(cell)” to convert it to degrees.

Understanding Radians and Degrees
To use radians & degrees in Excel right, we need to understand what they mean. That’s why we’ve made a section named “Understanding Radians & Degrees”. It has two subsections:
- One explains what radiants are.
- The other explains degrees.
Definition of Radians
Radians are a unit of angular measurement that represents the central angle formed by an arc. It is defined as the ratio of the length of an arc to its radius, and the measure of one complete revolution is equal to 2π radians. Essentially, radians describe how much of a circle’s circumference an angle covers.
When performing math operations that involve angles, radiands are often preferred over degrees due to their mathematical convenience and uniformity across equations. However, degrees are still commonly used in everyday situations.
It’s important to note that converting between radians and degrees requires multiplying or dividing by π/180, depending on the direction of the conversion. This can be done manually or using Excel’s built-in conversion functions.
A true fact is that the concept of radians was first introduced by Roger Cotes in the early 18th century.
Degrees: The unit of measurement for angles that high school math teachers insist will be useful one day (even though we all just use our phones to measure angles now).
Definition of Degrees
Degrees are a unit of measurement used to indicate the size of an angle. It is often represented by the symbol ‘°’, and a full circle has 360 degrees. The degree is subdivided into minutes and seconds, which are smaller units of measurement used for more precise angles.
When measuring angles in degrees, a right angle (90°) is formed by two perpendicular lines, while a straight line forms 180°. Degrees are commonly used in fields such as geography, astronomy and engineering.
It is essential to have an understanding of degrees when converting them to radians, which is another unit of angle measurement used primarily in mathematics and physics. Radians are defined as the ratio between the length of an arc and its radius in a circle.
Interestingly, the concept of degrees originated from ancient Babylonian astronomers who divided the circular path of celestial bodies into 360 equal parts. This measurement system was then adopted by Greek mathematicians during the Hellenistic period and has remained in use ever since.
Why do radians need a conversion formula? So they can finally be accepted into the degrees community.
Conversion Formula for Radians to Degrees
Converting radians to degrees is easy! Use the formula. This section will explain it. Plus, we’ll give an example calculation to help you out.
Example Calculation
To Calculate Radians to Degrees professionally, the following conversion formula needs to be applied: Degrees = Radians x (180/π).
For the heading ‘An Illustrative Example‘, a table has been created with two columns- one for radians and another for degrees. For example, if the given radian input is 1.5, then by using the above formula we get 85.94 degrees. The same has been illustrated in the table.
| Radians | Degrees |
|---|---|
| 1.5 | 85.94 |
To avoid confusion and get correct results, be sure to use true values that match each other correctly.
Furthermore, it’s essential to remember that radians are dimensionless, whereas degrees measure angles in a circle.
According to sources from Mathisfun, “Radians measure angles just like degrees do”.
Excel makes converting radians to degrees as easy as calculating how much pizza you can eat in one sitting.
Using Excel for Converting Radians to Degrees
Converting radians to degrees in Excel? No problem! You can use a simple and strong solution inside the software. This section on “Using Excel for Converting Radians to Degrees” has two sub-sections:
- “Entering Radian Value in Excel”
- “Using Excel Formula to Convert Radians to Degrees”
With these, you can accurately do the calculation in an Excel spreadsheet – easy peasy!
Entering Radian Value in Excel
To input radian values in Excel, simply select the cell where you want to enter the value and type it in using the standard format. Remember that radians are represented by Greek letter ε, so be sure to use this symbol. Additionally, you can convert degrees to radians using the function =RADIANS(value) or degrees by using =DEGREES(value). This will ensure accuracy when working with trigonometric functions in Excel.
It is important to note that Excel uses radians by default when calculating trigonometric functions such as SIN, COS, and TAN. Therefore, if you are entering values in degrees for these functions, be sure to convert them into radians first. This can easily be done using the DEGREES function mentioned above.
For greater accuracy when converting values, it is recommended to use a calculator or an online converter tool. Additionally, remember to always double-check your entries before relying on them for calculations.
Pro Tip: When working with complex or large datasets involving radians and degrees conversions, consider using macros or VBA code to automate the process and save time. Transforming radians into degrees in Excel is like turning a snake into a ladder – confusing, but rewarding when done right.
Using Excel Formula to Convert Radians to Degrees
If you have radians that need to be converted into degrees, consider the convenience of using Excel formulas for this task. With a few steps and accurate inputs, these formulas will provide you with the correct answer in no time.
Here’s a 6-step guide to convert radians to degrees through an Excel formula:
