"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

multiply the result by 24
like this =SUM(A2:G2)*24

Not for points but to expand on Saurabh and ProfJJ's suggestions, time in Excel is represented by a partial number, ie decimal less than 1, 12:00 Noon for example is 0.5, 18:00 is 0.75, the decimal being the portion of a day 12 of 24 = 0.5, 18 of 24 = 0.75. Format your values with comma formatting and you will see the equivalents for your times.

When adding up the times you are adding up the decimal numbers and it is adding up to more than one days worth of hours; when the formatting as hh:mm is applied, it is ignoring the day part and only showing the remaining hours.

Using the format [h]:mm:ss as suggested by Saurabh tells excel to include the days as hours.

Multiplying by 24 as suggested by ProfJJ converts the result to a number of hours as a proper number rather than a portion of a day.
