What is a BTU per hour?
The rate US heating and air conditioning is sold in. A 12,000 BTU/h unit is one "ton" of cooling and about 3.5 kilowatts of heat moved.
What is a watt?
The SI unit: one joule every second. A watt is a rate, not an amount, which is the distinction between it and the watt-hour on your electricity bill.
How many watts are in a BTU per hour?
One BTU per hour is 0.29307107 watts. Going the other way, one watt is 3.4121416 BTU per hour. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
