Thank you for the explanation. I believe I was trying to make things more complicated then they were. Would you say that my first formula was correct for finding the power rating? I was clearly mistaken when I tried to say BTU and BTU/h were the same for the second formula. Thanks again!

I searched the internet for the last 2 hours learning and understanding the Watt/Watt Hour/BTU conversions using data collected. I am not sure what I might be missing, but Wikipedia has supported that a defined Watt ~ 3.412 BTUs. Some simple constants: 1 Watt (W) = 1 Joule per second 1 BTU Hour (BTU/h) ~ 1055.05585 J 1 hour (h) = 3600 seconds (s) So, inherently, a simple formula can be derived to convert BTUs into what I believe should be Watts: W = Joules(BTUs)/Time Elapsed(seconds) OR 1055.05585/3600 ~ .293 W Rating Their number of 3.412 has apparently been used by applying: W = 1 Hour (Seconds)/Joules OR 3600/1055.05585 ~ 3.412 W This makes no sense to me and appears to be the inverse of a Watt. Once the Watt has been calculated, you simply multiply by the time of usage: Watts * Time (in hours)
