To successfully implement the formula in the calculator, the consumer or the buyer of the appliance should note the elements of the formula and their units and do any necessary conversion to fit the formula.
Note that rounding errors may occur, so always check the. You can view more details on each measurement unit: kilowatt-hours or TJ The SI derived unit for energy is the joule. The consumer will estimate the cost of energy an appliance will consume even before buying any appliance by considering the power rating provided for the appliance and applying the above formula. We assume you are converting between kilowatt hour and terajoule. Divide the 50 watts by 1000 to get 0.05kW In the case of an appliance rated at 50 watts and used for 1 hour the energy consumption (kWh) calculation is Ĭonvert the watts into kilowatts. In the case the appliance X is used for 15 minutes, the energy calculation is as follows Ĭonvert the minutes into hours. Since these two units of measurement represent different quantities you must also use the number of hours in your equation to get proper values. For instance, taking an appliance X rated at 3kW that is used for 4 hours, the energy consumed (kWh) is 12kWh. The Formula The formula for converting kWh to kW is very simple but it requires knowing over how many hours you would like the Kilowatts for.
Calculation:įor the calculation of kWh, all you need to have and the note is the power and the number of hours of consumption. It is important to note that the power rating should be in kilowatts (kW), and time should be in hours (h). P = Power defined as the rating for an appliance (kW). Kilowatts to kilowatt-hour conversion can apply the formula:Įnergy (E) is equal to electrical power (P) times time (T) in hours.Į = energy defined by the amount of electricity used (kWh). Conversion Chart Conversion is easy: Need help x This converter is very easy. Below is a sample conversion table for w to kw. Conversion Chart / Units of Power Converter, International System (SI) kilowatt: 1 Measurement Conversion > Engineering Converters > Units of Power Converter > International System (SI) kW - Kilowatt. To convert watts to kilowatts, divide the watts by 1000 to get the kilowatts. So, the answer to the question what is 50 watts in kilowatts is 0.05 kw. The conversion involves watts to kilowatts and kilowatts to kilowatts-hour. Kilowatts to kilowatt-hours is a significant conversion in electricity billing as it reflects the rate of electricity used and the total amount of energy used. Kilowatt-hour is the basic unit for energy bills as it’s used to calculate the energy costs and a way to quantify the amount of energy used. Kilowatt-hours (kWh) is the electricity demand for an appliance to run over a given period. Kilowatts (kW) is equivalent to 1000 watts. The power in kilowatts P (kW) is equal to the power in milliwatts P (mW) divided by one million: P (kW) P (mW) / 1000000.
#Kwh to kw conversion how to
Watt is the standard unit of electrical power. kW to mW conversion calculator How to convert milliwatts to kilowatts. It is very vital for a consumer when purchasing the appliance as the consumer can estimate the energy supply required and the cost of the energy to use. The appliance manufacturer labels the power rating during the packaging of the equipment. = 2655223.Electrical appliances have a power rating given in watts or kilowatts that indicates the amount of electricity the device requires to run and provide the necessary output. Therefore, in other words, one kilowatt times one second, or one kilowatt-second, is the same as 1000 joules. In relation to the base unit of => (joules), 1 Kilowatt Hour (kWh) is equal to 3600000 joules, while 1 Terajoules (TJ) = 1000000000000 joules. How to convert Kilowatt Hour to Terajoules (kWh to TJ)?Īlways check the results rounding errors may occur. 1 Background Toggle Background subsection 1.1 1988: Alternative Motor Fuels Act 1.2 1994: Gasoline gallon equivalent 1.3 2000: Petroleum-equivalent fuel economy 1.4 2007: X Prize 1.
