I need to know how to convert the roof pitch stated at 6/12 into degrees. I
know I have a rise of six inches per foot. I am using Excel 2007 and cannot
seem to get the formula correct. Please help me out. This is really bugging
me Thanks

hi
in trig...
TAN(a)=Rise/Run
but all that will give you is 50% slope(grade).
see this site....

it will calculate degrees, grades, etc.

I think you want to calculate ratio.

Try this formula:

=DEGREES(ATAN(rise/run))

You can make two columns, the first column being the rise, and the second
column being the run. The third column is the calculated ratio of the
rise/run. In the fourth column type the above formula.
