The formula you need to you is of the form
Explanation: Essentially we are dividing a time by one second, converting it to seconds, and then multiplying it by 100 to get the centiseconds.
Note: Make sure the format of your column is a number if the result doesn't work.
A1 is just a placeholder for whatever cell you want to use. Also I believe your conversion is wrong.
If the excel SECOND function returned a floating-point number:
Generally, if you know how to extract minutes and seconds, creating a formula is very straight forward. You know there are 60 seconds in a minute and 100 centiseconds in a second, the total number of centiseconds should be
=MINUTE(A1)*6000 + SECOND(A1)*100
However the excel
SECOND() function only returns integers, and there are no functions that return smaller time steps, so it does not work this way.
