For reference, the wavelength of ultraviolet light is in the range 100-400 nm, visible light is in the range 400-800 nm, and infrared light is in the range of 800 nm - 10 microns and beyond. It is possible the information provided by us may not be accurate for non EVGA power supplies of the same wattage. See the links at right for other calculators. The watts equation for an electrical circuit takes into account the voltage across the circuit V, measured in volts, and the current I, measured in amps, passing through it.In mechanics, the definition of power is the rate of doing work W.It's defined as W/t, where t is the time it takes for the work to be completed. Electric power is defined as the rate, per unit time, at which an electric circuit transfers its electrical energy. h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Power: Wavelength Photons: per: Add . On the home page. This calculator has led to easier conversions from Amps to Watts. Effortlessly compute speed or power for all important parameters, such as weight, grade, position and tire type. The standards for racing cyclists are also divided into different categories. The formula is. Converting watts to amps can be done using the power formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts.. Figure out how much power you are consuming. Calculating the AC single phase watts to amps I (A) = P (W) / (PF x V (V), where the phase current in amps is calculated by dividing the real power in watts by the power factor multiplied by voltage in volts For example; If the power consumption is 186 watts and the power factor is 0.4. Use this power converter to convert instantly between horsepower, kilowatts, megawatts, volt amperes, watts and other metric and imperial power units.
