Calculating percent error is a crucial step in data analysis, especially in scientific and engineering applications. It allows you to determine the difference between a measured value and a theoretical or expected value, expressed as a percentage. In this guide, we will show you how to calculate percent error on Google Sheets, a powerful tool for data analysis and visualization.
Why Calculate Percent Error?
Calculating percent error is essential in various fields, such as physics, chemistry, and engineering, where accurate measurements are critical. It helps you to identify the precision and accuracy of your measurements, and to determine whether your results are within an acceptable range. By calculating percent error, you can also identify areas where your measurements may be biased or inaccurate, and take corrective action to improve your results.
What is Percent Error?
Percent error is the difference between a measured value and a theoretical or expected value, expressed as a percentage of the expected value. It is calculated using the following formula:
Percent Error = ((|Measured Value – Expected Value|) / Expected Value) x 100%
Calculating Percent Error on Google Sheets
In this guide, we will show you how to calculate percent error on Google Sheets using formulas and functions. We will also provide examples and step-by-step instructions to help you get started.
Stay tuned for the next section, where we will dive deeper into the process of calculating percent error on Google Sheets.
How To Calculate Percent Error On Google Sheets
Calculating percent error is a crucial step in scientific and engineering applications to determine the difference between a measured or observed value and a theoretical or accepted value. Google Sheets provides an easy way to calculate percent error using formulas and functions. In this article, we will guide you on how to calculate percent error on Google Sheets.
What is Percent Error?
Percent error is the difference between a measured or observed value and a theoretical or accepted value, expressed as a percentage. It is a measure of the accuracy of a measurement or calculation. Percent error is calculated as the absolute difference between the measured and accepted values, divided by the accepted value, and then multiplied by 100.

Calculating Percent Error on Google Sheets
To calculate percent error on Google Sheets, you can use the following formula:
=(|Measured Value – Accepted Value| / Accepted Value) * 100
This formula calculates the absolute difference between the measured and accepted values, divides it by the accepted value, and then multiplies it by 100 to get the percent error.
Step-by-Step Guide
Here’s a step-by-step guide to calculate percent error on Google Sheets:
- Enter the measured value in cell A1.
- Enter the accepted value in cell B1.
- Enter the formula =(|A1-B1| / B1) * 100 in cell C1.
- Press Enter to calculate the percent error.
The result will be the percent error, which will be displayed in cell C1.
Example
Suppose you measured the mass of an object to be 250 grams, and the accepted value is 240 grams. To calculate the percent error, you can use the following formula: (See Also: How To Make All Cells Wider In Google Sheets)
=(|250-240| / 240) * 100
This formula calculates the absolute difference between the measured and accepted values, which is 10 grams. Then, it divides the absolute difference by the accepted value, which is 240 grams, to get 0.0417. Finally, it multiplies the result by 100 to get the percent error, which is 4.17%.
Recap
In this article, we learned how to calculate percent error on Google Sheets using formulas and functions. We also discussed the importance of percent error in scientific and engineering applications. By following the step-by-step guide and example, you can easily calculate percent error on Google Sheets and analyze the accuracy of your measurements or calculations.
Key points to remember:
- The formula to calculate percent error is =(|Measured Value – Accepted Value| / Accepted Value) * 100.
- Enter the measured value and accepted value in separate cells.
- Enter the formula in a new cell and press Enter to calculate the percent error.
- Percent error is a measure of the accuracy of a measurement or calculation.

FAQs: How To Calculate Percent Error On Google Sheets
What is percent error and why is it important?
Percent error is the difference between a calculated value and an actual value, expressed as a percentage. It’s an important concept in science, engineering, and other fields where accuracy is crucial. In Google Sheets, calculating percent error helps you identify the magnitude of the difference between your calculations and actual values, allowing you to refine your methods and improve accuracy.
How do I calculate percent error in Google Sheets?
To calculate percent error in Google Sheets, you’ll need to follow these steps: 1) subtract the actual value from the calculated value, 2) divide the result by the actual value, and 3) multiply the result by 100. You can use the formula: =((|calculated value – actual value|)/actual value)*100. For example, if your calculated value is 10 and the actual value is 12, the percent error would be: =((|10 – 12|)/12)*100 = 16.67%.
Can I use a formula to calculate percent error in Google Sheets?
Yes, you can use a formula to calculate percent error in Google Sheets. The formula is: =ABS((A2-B2)/B2)*100, where A2 is the calculated value and B2 is the actual value. You can also use named ranges or references to make the formula more readable and flexible.
How do I handle negative values when calculating percent error?
When calculating percent error, you’ll often encounter negative values. To handle this, you can use the ABS function to ensure the result is always positive. For example, if your calculated value is 10 and the actual value is 12, the percent error would be: =ABS((10-12)/12)*100 = 16.67%. The ABS function returns the absolute value of the expression, eliminating the negative sign.
Can I use Google Sheets’ built-in functions to calculate percent error?
Unfortunately, Google Sheets doesn’t have a built-in function specifically for calculating percent error. However, you can use the formula and functions I mentioned earlier to create a custom formula that calculates percent error. You can also use add-ons or scripts to extend Google Sheets’ functionality and create a custom percent error function if needed.
