Hello David & Paul, Thank you both for your input. The formula seems to work
now. I will come back to you if I encounter any other issues with this.

Regards

Dave

I think your problem is that Excel is treating your -ve time string as a

Try =IF(LEFT(A2)="-",-MID(A2,2,255)*24,A2*24)

Hello Paul,

I get #VALUE! when I apply the formula.

This is to do with gps co-ordinates in time (as you have already noted).
I need to take hh.mm.ss format to hh.mmsss - I have got the Latitude
calculation resolved; that was quite easy by cell total*24; i.e.
44.55.00*24
= 44.88333;
I'm still struggling with Longitude.
I am using the following now.

=(HOUR(E2)+(MINUTE(E2)/60)+(SECOND(E2)/(60*60)))*-1

Cell E2 has the following in it -0:33:18; I am trying to place the result
in
Cell I2.

Again I get #VALUE!

Thoughts?? & Thank you. Dave.
(PS - where are you in the world out of curiosity)

With your time (or 0:33:18) in A2:

Hello All,

I require help with the below formula.

=(0+(33/60)+(18/(60*60)))*-1

Certain numbers in the formula change.
The numbers that change are from left to right '0' '33' & '18'.

In this instance the '0' was a negative value (hence the *-1 on the end
of
the formula).

I have many rows in which these numbers vary.

How can I target the formula at one cell (where the data source is, eg.
-0:33:18) and place the result (in this case -0.555) in another?

Sorry if I am not explaining very well. I hope you can understand it
though.

Thank you for your Help. David.
