When working with numerical data in Google Sheets, it’s essential to understand how to set significant figures (sig figs) correctly. Significant figures are a way to express the precision and accuracy of a measurement or calculation, and they play a crucial role in various fields, including science, engineering, and finance. In this blog post, we’ll explore the importance of significant figures, how to set them in Google Sheets, and provide tips and best practices for working with sig figs.
Why Are Significant Figures Important?
Significant figures are essential in scientific and technical applications because they help to convey the precision and accuracy of a measurement or calculation. When working with numerical data, it’s crucial to understand the limitations of measurement and calculation, and significant figures provide a way to express these limitations. Inaccurate or imprecise measurements can lead to incorrect conclusions, and significant figures help to avoid these errors.
Significant figures are also important in finance and economics, where small errors can have significant consequences. For example, a small mistake in a financial calculation can result in a large error, and significant figures help to ensure that calculations are accurate and precise.
What Are Significant Figures?
Significant figures are a way to express the precision and accuracy of a measurement or calculation. They are based on the number of digits that are known to be accurate, and they are used to indicate the degree of precision of a measurement or calculation.
There are three main rules for determining significant figures:
- Non-zero digits are always significant.
- Zeros between non-zero digits are significant.
- Zeros at the beginning of a number are not significant.
For example, the number 123.45 has five significant figures, while the number 0.000123 has four significant figures. (See Also: How to Add More Columns Google Sheets? Super Easy Guide)
How to Set Significant Figures in Google Sheets?
Setting significant figures in Google Sheets is a straightforward process. You can set significant figures for a cell by using the “Format cells” option and selecting the “Number” format. Then, you can enter the number of significant figures you want to display in the “Significant figures” field.
Alternatively, you can use the “Format cells” option and select the “Custom number format” option. Then, you can enter the format code “#.###E+0” to display the number with the desired number of significant figures.
Here are some examples of how to set significant figures in Google Sheets:
| Number | Significant figures | Format |
|---|---|---|
| 123.45 | 5 | #.### |
| 0.000123 | 4 | #.###E+0 |
| 123456789 | 9 | #.###E+0 |
Best Practices for Working with Significant Figures
When working with significant figures, it’s essential to follow some best practices to ensure accuracy and precision:
- Always use the correct number of significant figures when performing calculations.
- Round numbers to the correct number of significant figures when necessary.
- Use the correct format for displaying significant figures.
- Check your calculations carefully to ensure accuracy and precision.

FAQs
Q: What is the difference between significant figures and decimal places?
A: Significant figures are a way to express the precision and accuracy of a measurement or calculation, while decimal places refer to the number of digits to the right of the decimal point. For example, the number 123.45 has five significant figures, but only three decimal places.
Q: How do I set significant figures for a range of cells in Google Sheets?
A: You can set significant figures for a range of cells in Google Sheets by selecting the cells, going to the “Format cells” option, and selecting the “Number” format. Then, enter the number of significant figures you want to display in the “Significant figures” field.
Q: Can I use significant figures in Google Sheets for calculations?
A: Yes, you can use significant figures in Google Sheets for calculations. When performing calculations, make sure to use the correct number of significant figures for each value, and round the result to the correct number of significant figures.
Q: How do I check for errors in my calculations when working with significant figures?
A: You can check for errors in your calculations by using the “Error” function in Google Sheets. This function will highlight any errors in your calculations, including errors in significant figures.
Q: Can I use significant figures in Google Sheets for financial calculations?
A: Yes, you can use significant figures in Google Sheets for financial calculations. When performing financial calculations, make sure to use the correct number of significant figures for each value, and round the result to the correct number of significant figures.
