Spatial Analyst / Flow accumulation and length questions

Hello,

I have a 20 meter GRID file I used as input to the flow accumulation and flow length functions.  The distance units are meters and the elevations are in feet.

I ran the flow accumulation and flow length functions and recieved the resulting grids.

My question is, what units are the results?  Are they meters? 

1) I assume the flow accumulation is a count of cells that accumulate to that cell.  Hence, the result is the cell value * 20 meters squared, correct?

2) For flow length, I assume the cell values are in meters, correct?

Thanks for your time!
