One kilowatt-hour (kWh) is equivalent to approximately 3,412 British Thermal Units (BTUs). This conversion is based on the energy content, where 1 kWh represents the energy used when one kilowatt of power is consumed for one hour. Therefore, to convert kWh to BTUs, you can multiply the number of kWh by 3,412.
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
One megawatt is equal to 1,000 kilowatts (kW), so one megawatt-hour (MWh) is equivalent to 1,000 kilowatt-hours (kWh).
To convert refrigeration tons (RT) to kilowatt-hours (kWh), you need to know the efficiency of the refrigeration system. Multiply the RT by 12,000 (which is the number of BTUs per hour in one refrigeration ton) to get the BTUs per hour. Then, divide the BTUs per hour by the system's efficiency to get the kWh required.
7.2×106 J. 1 kWh is equal to 3.6×106 J, and 1 J is equal to 2.778×10-7 kWh. 2 kWh is about 1/18 the amount of energy released from the combustion of a gallon of gasoline, and about 1.6 times the amount of energy released by the detonation of one kilogram of TNT. As of November, 2010, that amount of energy would cost about $0.36 to a resident of New York -- up from about $0.26 in 1990.
approximately 40 kWh
kWh is usage, while kW is power. One kW for one hour is one kWh, one kW for 30 minutes is 0.5 kWh ASO
1 kilowatt (kW) is equal to 1 kilowatt-hour (kWh) when used continuously for one hour. So, if you use a 1 kW appliance for one hour, it will consume 1 kWh of electricity.
There are 3.6 million joules in one kilowatt-hour (kWh).
There are 277.778 kilowatt-hours (kWh) in one petajoule (PJ).
The number of BTUs per cord of wood depends on the type of wood. One cord of cottonwood is equal to 16.1 million BTUs. One cord of hard maple is equal to 23.7 million BTUs, and one cord of red oak wood is equal to 24.4 million BTUs.
One ton of TNT is equivalent to approximately 4.184 billion British Thermal Units (BTUs).
There are 1 million kilowatt hours (kWh) in one terawatt hour (tWh).
