Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Custom Formats for Scientific Notation.
Reid notes that he can display numbers using scientific notation and they appear in Excel in the format 1.23E+03 or 1.23E-03. He would like the scientific notation to be shown differently, such as 1.23x10^3 or 1.23x10^-3.
There is no way in Excel to change the way in which scientific notation is displayed. The only workaround is to use a formula to put together a text representation of what you want. For instance, if a value that uses Excel's scientific notation is stored in cell C7, you could use the following formula:
=LEFT(TEXT(D7,"0.00E+0"),3) & "x10^" & RIGHT(TEXT(D7,"0.00E+0"),3)
This formula essentially pulls the left portion of the number (the part before the E) and combines it with the right part of the number (the part after the E) together with the "x10^" notation. The result is considered a text string by Excel; it cannot be used in subsequent calculations.
If you needed to do quite a bit of formatting in this manner, it would be a relatively trivial matter to create a macro that returned the formatted text string based on the number. Create it as a user-defined function and you could then use it in your formulas.
