The Scientific format displays a number in exponential notation, replacing part of the number with E+n, where E (which stands for Exponent) multiplies the preceding number by 10 to the nth power. For example, a 2-decimal Scientific format displays 12345678901 as 1.23E+10, which is 1.23 times 10 to the 10th power.

1. Select the cell or range (range: Two or more cells on a sheet. The cells in a range can be adjacent or nonadjacent.) of cells that you want to format.

   How to select a cell or a range

   To select	Do this
   A single cell	Click the cell, or press the arrow keys to move to the cell.
   A range of cells	Click the first cell of the range, and then drag to the last cell, or hold down SHIFT while you press the arrow keys to extend the selection. You can also select the first cell of the range and then press F8 to extend the selection by using the arrow keys.
   A large range of cells	Click the first cell in the range and then hold down SHIFT while you click the last cell in the range. You can scroll to make the last cell visible.
   All cells on a worksheet	Click the Select All button. To select the entire worksheet, you can also press CTRL+A. Note  If the worksheet contains data, CTRL+A selects the current region. Pressing CTRL+A a second time selects the entire worksheet.
   Nonadjacent cells or cell ranges	Select the first cell or range of cells, and then hold down CTRL while you select the other cells or ranges. You can also select the first cell or range of cells and then press SHIFT+F8 to add another nonadjacent cell or range to the selection. Note  You cannot cancel the selection of a cell or range of cells in a nonadjacent selection without canceling the entire selection.
   An entire row or column	Click the row or column heading. Row heading  Column heading  You can also select cells in a row or column by selecting the first cell and then pressing CTRL+SHIFT+ARROW KEY (RIGHT ARROW or LEFT ARROW for rows, UP ARROW or DOWN ARROW for columns). Note  If the row or column contains data, CTRL+SHIFT+ARROW KEY selects the row or column to the last used cell. Pressing CTRL+SHIFT+ARROW KEY a second time selects the entire row or column.
   Adjacent rows or columns	Drag across the row or column headings. Or select the first row or column; then hold down SHIFT while you select the last row or column.
   Nonadjacent rows or columns	Click the column or row heading of the first row or column in your selection; then hold down CTRL while you click the column or row headings of other rows or columns that you want to add to the selection.
   More or fewer cells than the active selection	Hold down SHIFT while you click the last cell that you want to include in the new selection. The rectangular range between the active cell (active cell: The selected cell in which data is entered when you begin typing. Only one cell is active at a time. The active cell is bounded by a heavy border.) and the cell that you click becomes the new selection.

   Note  To cancel a selection of cells, click any cell on the worksheet.

2. On the Format menu, click Cells.
3. On the Number tab, click Scientific in the Category list.
4. In the Decimal places box, enter the number of decimal places that you want to display.

Notes

• A number format does not affect the actual cell value that Microsoft Excel uses to perform calculations. The actual value is displayed in the formula bar (formula bar: A bar at the top of the Excel window that you use to enter or edit values or formulas in cells or charts. Displays the constant value or formula stored in the active cell.).
• The maximum limit for number precision is 15 digits, so the actual value that is displayed in the formula bar may change for large numbers (more than 15 digits).
• To reset the number format, click General in the Category list. Cells that are formatted with the General format have no specific number format. However, the General format does use exponential notation for large numbers (12 or more digits). To remove the exponential notation from large numbers, you can apply a different number format, such as Number.
