Put 6:30:00 in a cell, let's say A1.
In C42:
=C31-A1.
If C31 can be less than 6:30:00:
=MAX(0,C31-A1)

If you are likely to go over 24 hours, format custom as [h]:mm:ss to prevent tipping over at 24h.

| Sorry about this...follow-on question if I may please...
|
| I need to display a new result in C41 which will be the sum of C31
| (currently displaying 10:23:26 and then subtract 6:30:00 from this and
| display the new result in C41
|
| C31 is likely to change as I add more time worked but the 6 hours 30 minutes
| which I need to subtract will stay constant.
|
| I have tried a few ideas none of which have worked.
|
| Please excuse my ignorance but am I missing something fundamental here?
|
| Thanks & regards,

| If the time is in A1:
|
| =A1*24*30
|
| Time is stored as a faction of a day so *24 gives you the number of
| hours,
| including a decimal part for minutes and seconds

| | Hi there,
| |
| | I have a spreadsheet keeping track of time I spend on a project.
| |
| | The Total Time cell is formatted as Special and specified as
| [h:mm:ss:]
| |
| | I have a standard hourly rate and I would like to calculate the total
| time
| | spent & display the result in Pounds Sterling - the cell is already
| | formatted as Currency
| |
| | For example the Total Time is 10h:01mm:41ss: and I want to multiply
| this
| by
| | the Hourly rate which is 30 Pounds Sterling.
| |
| | What is the formula to achieve this please?
| |
