Advertisements Watts to amps conversion examples Power supplied to homes and businesses uses AC supply. In Europe, the UK, East Japan and most of Australia, South America, Africa andĪsia, the current changes direction 50 times per second, which is 50Hz.
In Northern America and Western Japan, this usually happens 60 times per second, or 60Hz / hertz. A flashlight with a battery uses a direct current.ĪC stands for alternating current, when the current periodically changes direction. North American homes typically use 120V for their electrical supply, whilst 230V is common acrossĭC stands for direct current, when the current flows in one single direction. In the hose analogy, the volts would be the water pressure.
They measure the force required to make the electrical current (amps) flow. It uses increased water volume and higher water pressure the same applies to the wattage if amps and volts are increased. Power (P) is the rate of energy transfer with the SI unit of 1 Watt 1 J/s. A water wheel would turn faster and longer, generating more energy if Need a quick unit conversion from wavelength (nm) to photon energy (eV). Multiplying amps (water volume) by volts (water pressure) gives you the wattage (the resulting power or energy). Watts represent the amount of energy produced by the amps and volts working together. In this analogy, the quantity (volume) of water would be the amps. Many people ask us for conversions between microwave measurement units so that they can compare the units we use, volts per metre (V/m), with watts per. It can be helpful to imagine electrical current as water in a hose. What are amps?Īmps are amperes, a unit which measures electrical current. To help understand the conversion of watts to amps, let's go through what each of these units represent. They were left in this form so that you could calculate a more accurate conversion factor.Advertisement Understanding watts, amps and volts For example, converting calorie per hour (IT) to watts, 4.0 is 4.1868 divided by 60, divided by 60 which is equal to 0.001163. Note that you must first complete the operations in the Multiply By column in order to have the correct factor. So, to convert directly from BTU/h (th) to cal/s (th) you multiply by 0.069998829. Or, you can find the single factor you need by dividing the A factor by the B factor.įor example, to convert from BTU/h (th) to cal/s (th) you would multiply by 0.2928751 then divide by 4.184. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into W then divide by the factor for B to convert out of W. To convert from W into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.ġ4.653555 W / 0.2930711 = 50 BTU/h Convert kilowatt-hour to watt-hour, megawatt-hour, BTU, kiloBTU, joules, kilojoules, megajoules, gigajoules, Enter the energy in one of the text boxes and. One kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour. Multiply by the value in the right column in the table below.ĥ0 BTU/h * 0.2930711 = 14.653555 W Kilowatt-hour is an energy unit (symbol kWh or kWh). To simply convert from any unit into W, for example, from 50 BTU/h, just Where S is our starting value, C is our conversion factor, and
