One Btu/h is equal to 0.29307107 watt. Convert 20000 BTU/hr to watts: P (W) = 20000 BTU/hr / 3.412141633 = 5861.42W Let’s do an example for California: Most … What is 10,000 btus per hour in kilowatts? Its symbol is kW/m². Example. The answer is 29.31 We’ve received a lot of questions about which generators are best for a certain capacity of an air conditioner. For this example, let’s take a 10,000 BTU portable AC with EER 12 and powered by 115. P (BTU/hr.) The EER is a simple ratio of the BTUs of the unit to the amount of power it consumes in Watts. One Btu/h is equal to 0.29307107 watt.
