Formatting for Hundredths of Seconds

Paolo wants to record times in an Excel workbook, but he needs the times to be precise, including hundredths of a second. What he would like is a format such as 1.41.73, meaning 1 minute, 41 seconds, and 73 hundredths.

This type of formatting can be easily applied to a cell in the following manner:

1. Select the cell or cells you want to format.
2. Choose Cells from the Format menu. Excel displays the Format Cells dialog box, and the Number tab should be displayed. (Click here to see a related figure.)
3. In the Category list, choose Custom.
4. In the Type box, enter the following: [h]:mm:ss.00
5. Click OK.

The format shows elapsed time, with hours, minutes, seconds, and hundredths of seconds. If you prefer, you can change what delimiters are used between each element of the time. For instance, if you want to use decimal points and drop off the hours, you can use the following format in step 4: mm.ss.00.
