The calculator works by filling in any of two of the three fields (volts amps watts) to calculate the value of the third field. Converting voltage to power measured in watts is easy using a simple Watt’s Law formula. The user must fill one of the two fields and the conversion will become automatically. Mathematically, the real power (watts) is related to the apparent power (VA) using a numerical relationship called power factor (PF) , which is expressed in decimal format and always has a value between 0 and 1.0. If a device has a nominal capacity of 300 VA and is powered by an AC line voltage of 120 V RMS , you can calculate the maximum expected current of 300 VA / 120 V RMS = 2.5A . You must obtain the VA of the load you want to convert to Watts , for this you can go to the nameplate or catalogs of the equipment (s) , you can also perform an Internet search with the reference of the equipment (s), commonly the power of these electrical devices They come in watts , however there are some inductive loads that have motors and a load assignment in VA. Find the power factor of the equipment for which you want to convert the power of VA to Watts. Watts calculation. It’s also possible to convert volts to watts if you know the resistance of the circuit. We design professional systems for home, business and government. Example 2: To convert watts to amps for a 12V DC 500mA power supply, enter 12 volts and .5 amps. As an example, a device with a nominal power of 525 Watts (watts) and a power factor of 0.7 results in a load of 750 VA. Differences, definition and what the VA and Watts are used for. The energy in watts consumed is related to the resistance in an electrical circuit. dBm, Volts, Watts Conversion dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). How to Convert Watts to Volts. Manage Cookies. Since many types of equipment are classified in watts or watts, it is important to consider the PF when sizing them. Rta: // As the formula indicates, you must multiply the VA by the freezer power factor , as follows: 5000VAx0.89 = 4450Watts. Convert the amps to watts with our electrical conversion calculator, plus learn the formulas for DC, single-phase AC, and three-phase AC circuits. The Volt amps and Watts are two different units and cannot be converted directly without including the power factor. Typically, electronic products display one or both of these values to provide information on the amount of energy they will consume or the amount of current they will consume. For example, let’s convert 24 volts to watts, for a DC circuit with 12 ohms of resistance. It is always preferable that you obtain the value of the power factor with the equipment catalogs. You can also use power factor reference tables . Privacy Policy | This table shows the commercial values of some UPS with power factors equal to 0.8: Both watts (Watts) and volts-amps (VA) are units of measurement of electrical energy. A freezer has a power of 5000VA and a power factor of 0.89 , how much power in Watts will the freezer have? Example 2: To convert watts to amps for a 12V DC 500mA power supply, enter 12 volts and .5 amps. These values are useful if you have to eliminate the heat generated by the device that consumes the watts or if you want to know how much you will pay your utility company for using your equipment, since it pays per kilowatt-hour (energy used for a period of time ). Watts to VA calculator VA to watts calculation. This calculator is only meant to convert the volt amps to watts and therefore alternating the values may give you wrong results. You can view more details on each measurement unit: mA or watt/volt The SI base unit for electric current is the ampere. A computer has a power of 500VA and a power factor of 0.92 , what is the power in Watts of the computer? This tool can convert any value as long as you enter the two other values. phase current I in amps (A): VL-L(V) = P(W) / (√3 Note that rounding errors may occur, so always check the results. The easy response is 4.8Watts, taking into account a power factor of 0.8 and using the VA conversion formula to watts: 6VAx0.8 = 4.8Watts. resistance. current / 99 $109.99 $109.99. An example of energy consumed in watts is the filament in a bulb. power factor PF times the watts (W), divided by the The sizing of a UPS, transformer or power plant to operate at 75 percent of its capacity results in equipment with a lower rating than what you expected . Manage Cookies.
