 # How To Convert Decimals to Percentages in No Time

Ready to learn how to convert decimals to percentages in three different ways? In this article, we’ll show you how to make that conversion manually, using Excel and R programming. Let’s get started!

## How To Convert Decimals to Percentages Manually

Converting decimals to percentages manually is a cinch! Just follow these easy steps:

1. Take your decimal (e.g., 0.45).
2. Multiply the decimal by 100 (0.45 × 100).
3. Add the percentage symbol (%) to the result (45%).

And there you have it! Your decimal has been transformed into a percentage. Let’s try another example: 0.375 × 100 = 37.5%.

Piece of cake, right? But hey, what about using Excel? Let’s have a look next.

## How To Convert Decimals to Percentages in Excel

Excel is not only fantastic for organizing data but also perfect for converting decimals to percentages in a jiffy. Here’s how:

1. Open Excel and type your decimal (e.g., 0,45) into a cell (e.g., A1).
2. Click on an empty cell (e.g., B1) where you want the percentage to appear.
3. Type this formula into the cell: =A1.
4. Press Enter, and the same value as in A1 will appear in B1 (e.g., 0.45).
5. Now, let’s format the value as a percentage:
6. Right-click the cell (e.g., B1) containing the result.
7. Select “Format Cells…
8. Choose the “Percentage” category and set the desired number of decimal places.
9. Click “OK” to apply the formatting.
10. The cell (e.g., B1) should now display the correct percentage: 45%. And that’s it! You’ve successfully converted a decimal to a percentage in Excel.

Let’s look at how we can use the power of R to do the same thing.

## How To Convert Decimals to Percentages in R

For those familiar with R, converting decimals to percentages is a breeze. Let’s see how it’s done:

1. Open R or RStudio and create a variable with your decimal (e.g., decimal <- 0.45).
2. Multiply the decimal by 100 to get your percentage: percentage <- decimal * 100.
3. Print your percentage: print(percentage).

And just like that, your percentage will be displayed in the console (e.g., 45).

Here’s the entire process in a neat little script:

decimal <- 0.45
percentage <- decimal * 100
print(percentage)

But what if you have a vector of decimals to convert? No worries, R has your back:

1. Create a vector with your decimals (e.g., decimals <- c(0.45, 0.375, 0.9)).
2. Multiply the decimals by 100 to get your percentages: percentages <- decimals * 100.
3. Print your percentages: print(percentages).

Your percentages will be displayed in the console (e.g., 45, 37.5, 90).

Here’s the full script for converting a vector of decimals to percentages:

decimals <- c(0.45, 0.375, 0.9)
percentages <- decimals * 100
print(percentages)

In conclusion, whether you’re converting decimals to percentages manually, with Excel, or using R, it’s a simple and straightforward process. Now you can confidently tackle these conversions and shine in any situation that requires you to switch between decimals and percentages.

Now let’s look at how to convert percentages to decimals easily. Happy converting! ##### Leonard
