title: Units of energy text: unit used for everyday electricity, particularly for utility bills, is the kilowatt-hour (kWh); one kWh is equivalent to 3.6×10 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, i.e., the average rate at which energy is transferred. One kWh/yr is about 0.11 watts. Natural gas in the US is sold in Therms or 100 cubic feet (100 ft = 1 Ccf). One Therm is equal to about 105.5 megajoules. In Australia, natural gas is sold in megajoules. In the most of the title: Kilowatt hour text: Kilowatt hour The kilowatt hour (symbol kWh, kW⋅h or kW h) is a unit of energy equal to 3.6 megajoules. If energy is transmitted or used at a constant rate (power) over a period of time, the total energy in kilowatt hours is equal to the power in kilowatts multiplied by the time in hours. The kilowatt hour is commonly used as a billing unit for energy delivered to consumers by electric utilities. The kilowatt hour (symbolized kW⋅h as per SI) is a composite unit of energy equivalent to one kilowatt (1 kW) of power sustained for one hour. One title: Kilowatt hour text: a sustained power of about 114 megawatts for a period of one year. The symbol "kWh" is commonly used in commercial, educational, scientific and media publications, and is the usual practice in electrical power engineering. Other abbreviations and symbols may be encountered: To convert a quantity measured in a unit in the left column to the units in the top row, multiply by the factor in the cell where the row and column intersect. All the SI prefixes are commonly applied to the watt hour: a kilowatt hour is 1,000 W⋅h (symbols kW⋅h, kWh or kW h; a megawatt hour title: Kilowatt hour text: of 1 MW from 0 MW in 15 minutes has a ramp-up rate of 4 MW/h. Hydroelectric power plants have a very high ramp-up rate, which makes them particularly useful in peak load and emergency situations. The proper use of terms such as "watts per hour" is uncommon, whereas misuse may be widespread. By definition of the units, a consumption of 1 kWh/100 km is exactly equivalent to a resistance force of 36 N (newtons), an idea taken up by the von Kármán–Gabrielli diagram. Several other units are commonly used to indicate power or energy capacity or use in specific title: Watt text: of a watt. A typical laser pointer outputs about five milliwatts of light power, whereas a typical hearing aid for people uses less than one milliwatt. Audio signals and other electronic signal levels are often measured in dBm, referenced to one milliwatt. The kilowatt (kW) is equal to one thousand (10) watts. This unit is typically used to express the output power of engines and the power of electric motors, tools, machines, and heaters. It is also a common unit used to express the electromagnetic power output of broadcast radio and television transmitters. One kilowatt is approximately equal to 1.34
