Error: you MULTIPLY 3.413 to go from watts to BTU, not divide. It's be more like 154,000,000 BTU, /12000 or 12,798 tons.
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 watt-hour; for instance, a 60 watt light bulb uses 60 watt-hours of power every hour, or 1.44 kwatt-hrs per day).

There is a direct correlation between watts and btu's, and that is:

watts * 3.413 = btu
