Hello Experts,

I always get confused on getting the correct time it requires to perform a task based on a set number and keep in minute/second format.
I need the outcome to be in the minute:second format 0:00:00
A1 is the time to perform the task (in this case 0:01:04)
A2 is the variable number to enter for the count of tasks to be completed (scenerio is 24)
(A2 will be keyed by end-user and is a variable number)
In my example 24 x 0:01:04 = 0:25:36

I am not sure if this is an excel expression or a vba change cell calcuation to derive this result.

Any assistance would be appreciated since I am stuck and need to use this format for numerous task activities.

Thanks,
Michael

Hello Michael,
There may be an easier way but this seems to work.  In my formula A1 contains the hh:mm:ss.  B1 contains the multiplier.  Here's the formula.

=TEXT(B1*SUM(HOUR(A1)*60^2,MINUTE(A1)*60,SECOND(A1))/86400,CHOOSE(MATCH(B1*SUM(HOUR(A1)*60^2,MINUTE(A1)*60,SECOND(A1)),{0,60,3600},1),":ss","m:ss","[h]:mm:ss"))

If you want the format to be consistent then you can this.  It's shorter.

=TEXT(B1*SUM(HOUR(A1)*60^2,MINUTE(A1)*60,SECOND(A1))/86400,"hh:mm:ss")
