In the realm of spreadsheets, Google Sheets stands as a powerful tool for organizing, analyzing, and manipulating data. From tracking budgets to analyzing sales trends, percentages play a crucial role in representing proportions and relationships within datasets. Understanding how to effectively change percentages in Google Sheets is essential for anyone seeking to extract meaningful insights from their data. Whether you need to convert decimals to percentages, format numbers as percentages, or perform calculations involving percentages, mastering these techniques will empower you to work with your data with greater precision and clarity.
Understanding Percentages in Google Sheets
Percentages represent a fraction of 100. They are commonly used to express proportions, ratios, and changes in values. In Google Sheets, percentages are treated as numerical values, allowing for a wide range of mathematical operations. Understanding the fundamental concepts of percentages is crucial before delving into the specific techniques for changing them.
Converting Decimals to Percentages
Decimals and percentages are inherently linked. A decimal represents a portion of a whole, while a percentage expresses that portion as a fraction of 100. To convert a decimal to a percentage, simply multiply the decimal by 100 and append the “%” symbol. For example, the decimal 0.75 is equivalent to 75%. Google Sheets automatically handles this conversion when you format a cell as a percentage.
Formatting Numbers as Percentages
Google Sheets offers flexible formatting options to display numbers as percentages. By default, numbers are displayed as their numerical values. To change this, select the cell(s) containing the numbers and click on the “Format” menu. In the “Number” section, choose the “Percentage” option from the dropdown list. This will format the selected cells to display their values as percentages.
Changing Percentages in Google Sheets
Once you have a grasp of the basics, you can begin to manipulate percentages within your spreadsheets. Here are some common scenarios and techniques for changing percentages in Google Sheets:
Manually Changing Percentage Values
The most straightforward method for changing a percentage is to directly edit the cell containing the value. Simply select the cell, type in the desired percentage, and press Enter. Google Sheets will automatically recognize the percentage format and display it accordingly. Remember to include the “%” symbol when entering a percentage value.

Using Formulas to Calculate Percentages
Google Sheets provides a wide range of formulas for performing calculations involving percentages. The most common formula is the percentage formula, which calculates a percentage of a given number. The syntax for this formula is “= (number * percentage) / 100”. For example, to calculate 20% of 100, you would use the formula “= (100 * 20) / 100”, which would result in 20.
Example Formulas for Percentage Calculations
- Calculate the percentage increase or decrease: = ((New Value – Old Value) / Old Value) * 100
- Calculate a percentage of a total: = (Value / Total Value) * 100
- Calculate the percentage difference between two values: = ((Value1 – Value2) / ((Value1 + Value2) / 2)) * 100
Using the PERCENTAGE Function
Google Sheets offers a dedicated function called PERCENTAGE for converting a decimal or fraction to a percentage. The syntax for this function is “=PERCENTAGE(decimal_or_fraction)”. For example, to convert the decimal 0.75 to a percentage, you would use the formula “=PERCENTAGE(0.75)”, which would result in 75%.
Using Conditional Formatting to Highlight Percentages
Conditional formatting allows you to apply visual styles to cells based on their values. You can use conditional formatting to highlight percentages that meet specific criteria, such as percentages above or below a certain threshold. This can be helpful for quickly identifying trends or outliers in your data.
Advanced Techniques for Changing Percentages
Beyond the fundamental techniques, Google Sheets offers advanced features for manipulating percentages. These features can be particularly useful for complex calculations and data analysis.
Using the SUMPRODUCT Function to Calculate Weighted Percentages
The SUMPRODUCT function allows you to multiply corresponding elements in arrays and sum the results. This can be used to calculate weighted percentages, where each value is assigned a weight. For example, you could use SUMPRODUCT to calculate the weighted average of a set of percentages based on their corresponding weights.
Using the ARRAYFORMULA Function to Apply Formulas to Ranges of Cells
The ARRAYFORMULA function enables you to apply a formula to an entire range of cells at once. This can be particularly helpful for performing percentage calculations on large datasets. For example, you could use ARRAYFORMULA to calculate the percentage change for each item in a list. (See Also: How to Insert Image in Google Sheets? A Quick Guide)

Frequently Asked Questions
How do I change a percentage to a decimal in Google Sheets?
To convert a percentage to a decimal in Google Sheets, simply divide the percentage value by 100. For example, to convert 50% to a decimal, you would use the formula “=50/100”, which would result in 0.50.
Can I format a number as a percentage without using a formula?
Yes, you can format a number as a percentage directly without using a formula. Select the cell containing the number, click on the “Format” menu, and choose the “Percentage” option from the “Number” section. This will automatically format the cell as a percentage.
How do I calculate the percentage difference between two numbers?
To calculate the percentage difference between two numbers, use the following formula: = ((Value1 – Value2) / ((Value1 + Value2) / 2)) * 100. Replace Value1 and Value2 with the two numbers you want to compare.
What is the difference between PERCENTAGE and the percentage symbol (%) in Google Sheets?
The PERCENTAGE function in Google Sheets is a dedicated function that converts a decimal or fraction to a percentage. The percentage symbol (%) is a formatting option that displays a number as a percentage. You can use either method to represent percentages in your spreadsheet.
Can I use conditional formatting to highlight percentages above a certain threshold?
Yes, you can use conditional formatting to highlight percentages above a certain threshold. Select the cells containing the percentages, go to “Format” > “Conditional formatting,” and create a rule that highlights cells where the percentage value is greater than your desired threshold.
