How to Enter Scientific Notation in Excel

Excel is one of the most widely used spreadsheet programs globally, with scientific notation being a frequently entered value in Excel. As such, understanding how to use scientific notation in Excel is a valuable skill for every individual interested in working with data. Scientific notation, also known as exponential notation, is a method of expressing numbers that are too large or too small to write in decimal form. This blog post will guide you on how to enter scientific notation in Excel, using different methods, including formatting cells and custom number formatting.

Understanding Scientific Notation:

Scientific notation is used to express numbers that are either too large or too small to be written in decimal form. The notation consists of two parts; a coefficient and an exponent.

The coefficient is a real number multiplied by 10 raised to the power of the exponent. For example, 1.23 x 10^3 means 1.23 multiplied by 1,000.

Method 1: Using Cell Formatting

If you want to use scientific notation in Excel, the easiest way is by changing cell formatting. The steps below show how to format a cell to display a number in scientific notation format:

1. Select the cell(s) you want to format.
2. Right-click on the selected cell(s) and click Format Cells.
3. In the Format Cells dialog box, click on Number, select Scientific from the Category list.
4. Select the number of decimal places you want to display, then click OK.

Method 2: Using Custom Number Format

If you want to use scientific notation in a formula or function, you can use Custom Number Format. Follow the steps below:

2. Press Ctrl + 1 to bring up the Format Cells dialog box.
3. Click on the Number tab, then click on Custom in the Category list.
4. In the Type box, enter the format code; for example, 0.00E+00 for two decimal places.
5. Click OK to save the format.

Method 3: Using Scientific Notation in Formulas

To use scientific notation in a formula, enter the coefficient followed by the letter “e” and then the exponent. For example, to enter 1.23 x 10^3 in a formula, type 1.23e3.

You can also enter a lengthy number in scientific notation using this method. For example, to enter the number 8376543210 in scientific notation, type 8.37654321e9. The number will be displayed in scientific notation format in the cell.
