Convert "Time Interval" in "hours : minutes : seconds" to seconds
I wish to compare the cost of telephone calls between various telephone
service providers available to me. I have downloaded a list of itemised call made by me from my present provider and I wish to compare the cost of each call if I had used alternative providers. I'm OK with the basic mathematical formulae - but I need to convert a "Call Duration" in "hh:mm:ss" format to seconds. (I could use the "Text to columns" facility and then multiply the " Minutes Column by 60 and the hours column by 360 - and add the three columns together but feel this is clumsy when there must be a "nicer - easier way) Thanks for your help.

Try
=(A1*1440)*60 Where A1 is the time interval HTH J "Ianukotnorth" wrote: I wish to compare the cost of telephone calls between various telephone service providers available to me.

If A1 contains the duration in hh:mm:ss, say: 10:10:10
Put in B1: =A1*24*60*60 and format B1 as general (or number) B1 will return the time in seconds: 36610 -- Rgds Max xl 97 --- GMT+8, 1° 22' N 103° 45' E xdemechanik <atyahoo<dotcom ---- "Ianukotnorth" wrote in message ...

If the time column is in "true" XL recognizable time format as you stated
(hh:mm:ss), then all you have to do is format your total cell, or even each individual cell (if you choose) to the custom format: [ss] The square brackets prevent the seconds from rolling over into minutes, and then over into hours. You could also link your individual time cells to a separate column, and format that column to [ss], so that you might have a displayed comparison. -- HTH, RD --------------------------------------------------------------------------- Please keep all correspondence within the NewsGroup, so all may benefit ! --------------------------------------------------------------------------- "Ianukotnorth" wrote in message ...

Ragdyer, The problem I find with this method is that you can't then do
calculation on that cell. For example a time interval of 01:00:00 formatted as [ss] give you 3600 but then in another cell if you try adding 1 to it you get 1.04, instead of 3601.

You can, you just have to understand it and how it is stored.
You can either use =D14+1/(24*60*60) and also format as [ss] or use =(D14*86400)+1 and format as General. -- HTH Bob Phillips "Jimbola" wrote in message ...

Formatting *only* changes the *display* of what the cell contains.
Your 01:00:00 cell contains *one hour*. When you add 1 to it, what do you *think* that you are adding? 1 day- 1 hour - 1 minute - 1 second ? ? ? On a new sheet, with 01:00:00 entered in A1, and formatted [ss]. In B1 enter: =A1+1 You'll get 90000 Which means the 1 (to XL), means one day (8640 seconds), added to one hour (3600 seconds). My suggestion was aimed at strictly providing a *display* mode of seconds. -- Regards, RD --------------------------------------------------------------------------- Please keep all correspondence within the NewsGroup, so all may benefit ! --------------------------------------------------------------------------- "Jimbola" wrote in message ...

Don't get me wrong, I understand how it works.
I was simply trying to point out that when u use [ss] what you see is not in a sense what you get. J "Ragdyer" wrote: Formatting *only* changes the *display* of what the cell contains.
