Time / 3600 does work, but needs to be rounded as it can return multiple decimal places. i.e. 1:24:53s returns 1.4147222222222222

Whereas my function disregards the seconds completely - it just depends on whether you want to include seconds or not.

Well, using your calculation, 00:01:00 will return 0.0166666666666667. Ignoring the seconds has nothing with this - all it accomplishes is making the calculation more complicated and the result less precise.

So why don't you delete the wrong CF "round(xTime / 3600, 2)"?

No need to delete the custom function as it has been corrected.
