About Energy Conversions
Energy conversion is important in physics, nutrition, engineering, and electricity. The Joule (J) is the SI unit of energy. A calorie (cal) is the energy needed to raise 1 gram of water by 1°C; a kilocalorie (kcal) is 1000 calories and is used in food nutrition labels. One kilowatt-hour (kWh) equals 3.6 million joules and is commonly used for electrical energy billing. The British Thermal Unit (BTU) measures energy in heating and air conditioning systems - one BTU equals approximately 1055 joules.
