A thousand joules is equal to a British thermal unit. 1,000 joules = 1 Btu So, it would take 2 million joules to make a pot of coffee. The term "joule" is named after an English scientistJames Prescott Joulewho lived from 1818 to 1889. He discovered that heat is a type of energy...
Watch out: Be sure to start with the right BTUH rating from your equipment. Take a look at the data tag on your air conditioner or heat pump and notice that you may be given both input BTUH and output BTUH. EER is calculated as ratio ofoutputBTUH toinputelectrical energy in Watt Hours...
It is also equal to one watt of power emitted or dissipated for one second, or watt second (Ws). In various applications, British thermal units (BTU) are used to express the unit for energy. One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (...
