## Units of energy – wikipedia electricity deregulation wikipedia

###########

The energy unit used for everyday electricity, particularly for utility bills, is the kilowatt-hour (kWh); one kWh is equivalent to 3.6×10 6 J (3600 kJ or 3.6 MJ). Electricity usage is often given in units of kilowatt-hours per year (kWh/yr). This is actually a measurement of average power consumption ag gaston funeral home birmingham al, i.e., the average rate at which energy is transferred. One kWh/yr is about 0.11 watts.

The calorie equals the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree, from a temperature gaz 67 of 14.5 degrees Celsius, at a pressure of 1 atm. For thermochemistry a calorie of 4.184 J is used, but other calories have also been defined electricity billy elliot instrumental, such as the International Steam Table calorie of 4.1868 J. Food energy is measured in large calories or kilocalories, often simply written capitalized as Calories (= 10 3 calories).

In spectroscopy and related fields it is common to measure energy levels in units of reciprocal centimetres. These units (cm −1) are strictly speaking gas in oil not energy units but units proportional to energies, with h c ∼ 2 ⋅ 10 − 23 J c m {\displaystyle \ hc\sim 2\cdot 10^{-23}\ \mathrm {J} \ \mathrm {cm} } being the proportionality constant.
