Fast Fourier Transform outputs in Excel

If I take a Fourier Transform of Acceleration data in Excel, what units will
the output data be in?

The first cell will be the sum of your data, so I guess it's in the same
units.
If your output appear to be a little large in your analysis, you may need to
divide each cell by the size of your data. (ie divide by 16, 32, etc) Use
=IMDIV( ). Of course, it depends on what you are doing. Any specific
questions on a small sample?
