    very interesting stuff, the French have used the 10 hour system as well, 
    many clocks still survive.

    What I usually do when I need to enter data as 32�45'10" is simply enter 
    the data as: "=32+45/60+10/3600" into a cell. I know it is not what you 
    want it to be, but at least you can edit and change it.
    The other thing you can do is entering the data as time, so as 
    "32:45:10". The only thing is that you will have to multiply the figures 
    with 12 in order to use them in your calculations and you cannot edit 
    them. So in cell A1 you put the figure 32:45:10 and when you need the 
    sinus of it you say in cell B1 "=SIN(A1*12/180*PI())".
    Hope this helps
