Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000. Use the following formula to calculate kWh: Given torque in any unit, and speed in rpm, calculate power in watts or hp. Power = Current 2 * resistance. Bike Calculator. com Amplifier power: 80 watts continuous average power @ 4 ohms (2 channels driven, THD 0. It is possible the information provided by us may not be accurate for non EVGA power supplies of the same wattage. During an emergency is not the time to discover your home's wattage needs. Amps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Try our amps to watts calculator.. How to Convert Watts to Amps. Power Supply Calculator. This is a high-end calculator used for calculating power factor.The general formula used in this calculation is PF=P/S, where P - watts, S=V×I - volt-amperes. A version for US units is here. Cooler Master Power Supply Calculator will help you to select a suitable power supply unit for your system. Electric power is defined as the rate, per unit time, at which an electric circuit transfers its electrical energy. The calculator estimates both the idle and full load power consumptions and recommends a PSU wattage rating for the selected components. Power: Wavelength Photons: per: Add . Power = Energy / time And this is 488.36 Kilo Watts of power (since 1J/s = 1W) 1758120 kilojoule/hour = 488.36666667 kilowatt hour 488 kwh for 1 hour For 4 hours 488/4 = 122kw For 8 hours 488/8 = 61kw UPS Selector. Speaker cab unknown watts/ohms. The most essential of the equations the Speed&Power Calculator is based on: The following equations take into account all of the relevant resistance components: Rolling friction including the dynamic (speed-dependent) rolling friction, air drag including the influence of wind speed, mechanical losses, and uphill/downhill forces. P = I 2 * R. Watts = Amps 2 * Ohms. Power (P) in Watts is the resistance in ohms times of the current square. Just enter the two values of any parameter, to get remaining two.
