Well, the bigger problem here is that a watt is a measure of
power (engergy/time) and a BTU is a unit of energy. There is no
dimensionless conversion factor between the two.
Huh?
A Watt has no time constant. A watt is an amount of energy consumed at a
moment (ie, a 60 watt light bulb), not an amount of energy over time (like a
watthour; for instance, a 60 watt light bulb uses 60 watthours of power
every hour, or 1.44 kwatthrs per day).
Since you like Wikipedia so much, why don't you look it up:
http://en.wikipedia.org/wiki/Watt
Watt is not amount of power but amount of power produced during time, i.e.
its speed of energy consumption.
However kwatthour (I've never heard of watthour, but I suppose that
maybe used too..) is actually amount of energy consumed  more precisely
X kwr its how much energy device would consume if it were consuming
energy at exactly the same speed of X kw for entire hour.
