How to show time with milliseconds in Excel?

Author: Kelly Last Modified: 2020-04-26

For example a recorded time contains milliseconds, such as 10:33:50.235. When I type this time into a cell in Excel, the time shows as 33:50.2. After changing to the time format, the time shows as 10:33:50 AM with milliseconds disappearing. Is there any way to show time normally with remaining milliseconds in Excel? Yes, the following method will help you solve it easily.

This method will walk you through creating a custom time format to show time with milliseconds in Excel. Please do as follows:

1. Select the time cells that you will show time with milliseconds, right click and select the Format Cells from the right-clicking menu. See screenshot:

2. In the opening Format Cells dialog box, go to Number tab, click to highlight the Custom in the Category box, and then type the format code hh:mm:ss.000 into the Type box.

3. Click the OK button. Then you will see the milliseconds are showing with time as below screenshot shown:

Tip: Save the formatted time as Auto Text entry, and reuse its formatting in future easily
Normally we can apply custom format for cells with adding custom format code in the Format Cell dialog box in Excel. However, this custom format code is only saved in this workbook, and we can’t apply the custom format in other workbooks directly. Kutools for Excel’s AutoText utility enables us to save a formatted data/cell as an Auto Text entry, so that we can copy its custom format to other ranges of any workbooks directly.

ich brauch die Uhrzeit in Millisekunden als statischen Wert. Excel gibt mit der Tastenkombination (command + shift + Semikolon) die Uhrzeit statisch aus. Allerdings mit den Werten 00,000 für Sekunden und Millisekunden. Kennt jemand eine Lösung für dieses Problem? Die Eingabe von statischen Zeitwerten müsste relativ schnell geschehen (ca. 100 Werte innerhalb von 30-40 Minuten).

Hi there,

As far as I know, you cannot show milliseconds with the shorcut key. You can use the VBA method below:

1. Select the cell where you want to show the time in milliseconds, and then press Ctrl + 1 to open the Format Cells dialog.
2. Select Custom, and copy and paste hh:mm:ss.000 in the Type input box. Then click on OK to close the dialog.
3. Press Alt + F11 to open the VBA window, and then click Insert > Module.
4. Copy and paste the following code into the module window.
Sub TimeStamp()
'Update by ExtendOffice 20220902
    ActiveCell.Value = Format(Now, "hh:mm:ss") & Right(Format(Timer, "0.000"), 4)
End Sub

5. Click F5 to run the code.

Hope this could help you 🙂

I need 6 digits of precision, but "hh:mm:ss.000000" throws an error "Microsoft Excel cannot use the number format you typed"
How to I get 6 digits of milliseconds?

Hi there, instead of formatting the cell as a time, you should format it as text to show more then 3 digits of milliseconds:

1. Select the cell range where you will input thoses times with more then 3 digits of milliseconds.
2. Press Ctrl + 1 to open the Format Cells.
3. On Number tab, select Text in the Category list. Then click OK.
4. Enter the times in these cells.

...but when you go back to edit the number in the formula bar, the milliseconds are gone (as shown in video). That makes editing very difficult.
Our local format is "mm:ss,000" (not using hours in this case). When I enter number "00:40,123" it displays correctly in the cell, but in the fomula bar it shows "00:00:40". If I enter the formula bar and hit enter, the number in the cell then displays "00:40,000" - losing those crucial milliseconds. I have yet to find a reason, or even more important - a solution.

Something to watch out for: in some locales it won't work if you use this exact solution. In my version you need to use the format "uu:mm:ss,000" (that's a comma instead of a decimal point, and u is for "uren", dutch for hours).
Not sure whether it has to do with windows version, windows language, windows regional settings, used locale or office version.

For those of you who still want to show a decimal instead of a comma (like me), you can use this workaround (if your value is in cell A1)


Or adapt where necessary for your locale.
