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:

- Take your decimal (e.g.,
**0.45**). - Multiply the decimal by 100 (
**0.45 × 100**). - 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:

- Open Excel and type your decimal (e.g.,
**0,45**) into a cell (e.g.,**A1**). - Click on an empty cell (e.g.,
**B1**) where you want the percentage to appear. - Type this formula into the cell:

.**=A1** - Press Enter, and the same value as in A1 will appear in B1 (e.g.,
**0.45**). - Now, let’s format the value as a percentage:
- Right-click the cell (e.g.,
**B1**) containing the result. - Select “
**Format Cells…**“ - Choose the “
**Percentage**” category and set the desired number of decimal places. - Click “
**OK**” to apply the formatting. - 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:

- Open R or RStudio and create a variable with your decimal (e.g.,

).**decimal <- 0.45** - Multiply the decimal by 100 to get your percentage:

.**percentage <- decimal * 100** - 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:

- Create a vector with your decimals (e.g.,

).**decimals <- c(0.45, 0.375, 0.9)** - Multiply the decimals by 100 to get your percentages:
`percentages`

.**<- decimals * 100** - 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!
