The school where I did my PPL used to log time to the nearest 5 minutes, but charge decimal time. They had a conversiont table they used, which, off the top of my head, went something like:
05 min = .1
10 min = .2
15 min = .3
20 min = .3
25 min = .4
30 min = .5
35 min = .6
40 min = .7
45 min = .7
50 min = .8
55 min = .9
I think the main thing to take from this thread, though, is that there are so many different ways of converting - but at the end of the day no one really cares so long as it is roughly right.
