Mark,
Dug this formula up using Google [wanted to know myself seeing you asked]
Cam from a University of Hawaii electronics website. hope it is of use:
Many batteries today are rated in CCA or RC. CCA is Cold Cranking Amps. CCA is approximately equal to the RC of a battery times five. [1000 CCA is about 190 RC]. RC is Reserve Capacity. You can convert RC to amp/hours by the following formula:
Amp/Hours = (Reserve Capacity / 2) plus 16

Mark, I Dont know too much about the subject but I got the formula from the following page:
http://www.chem.hawaii.edu/uham/bat.html
Hope this helps. The search query I used was "formula for converting cold crank amps to amp hours" - it was the first item on the page.
