In many uninterruptible power supplies below 2000 VA, it is common to find a power factor less than 1.0 and, in many cases, as low as 0.6 for smaller systems. Note: It can not be converted from wat to dc watts, because the VA power only applies to AC currents 🎯Table of VA to Watts for UPS (Power factor of 0.8): 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. 1000va to watts converterġ000 VA equals 800Watts, with a power factor of 0.8 and using the formula: 1000VAx0.8 = 800Watts. Assuming a power factor of 0.8 the result would be 400Watts. To convert 500 VA to Watts you must have the power factor. Table of equivalences from watts to watts for systems that have a power factor equal to 0.8. Rta: // As the formula indicates, you must multiply the VA by the freezer power factor , as follows: 5000VAx0.89 = 4450Watts. Rta: // You must multiply the variables as indicated by the formula VAxF.p , resulting in: 500 × 0.92 = 460 Watts Example 3, conversion from going to watts for a freezerĪ freezer has a power of 5000VA and a power factor of 0.89 , how much power in Watts will the freezer have? Example 2, how much power a computer has in wattsĪ computer has a power of 500VA and a power factor of 0.92 , what is the power in Watts of the computer? Rta: // Only the VA must be multiplied by the power factor , as follows: 2800VAx0.91, the result will be: 2548 Watts. ☝How to convert from VA to WattsĪ clothes dryer has a power of 2800VA and a power factor of 0.91 , how much power in Watts does the dryer consume? It is always preferable that you obtain the value of the power factor with the equipment catalogs. The values required to perform the conversion are only 2 (VA and FP) , these two values can be obtained from the nameplates or by measuring with specialized equipment, such as multimeters or power meters, however you can also obtain estimated values of the Power factor here , these values are reference because each particular equipment will have a different value. The formula to perform the conversion comprises three variables (VA, Watts and power factor) , which are related in the previous formula. Fp = The power factor, is a value of each team, however there are some tables with reference power factors.VA = VoltAmpere (S), own value of each equipment, commonly are powers of the UPS, Transformers, motors, air conditioners, elevators and inductive equipment that have motors.
Watts = Active power (P) or watts, this is the value to be found.Therefore to convert BTU/h into Watts you need to divide by 3.41 to convert Watts into BTU/h you need to multiply by 3.41.To convert from VA to Watts you simply multiply the VA by the Load power factor , as shown by the formula of VA to Watts.Ĭommonly the power factor can be obtained by performing a search on the Internet with the references of the equipment , however another way is to use a table with common power factors . BTUs/h are normally used in the definition of the cooling power of air conditioning systems as well as of the heating power of fuel.įor W to BTU/h conversions, 1 W is equal to 3.41 BTU/h. A BTU is defined by the quantity of heat required to raise the temperature of 454 grams of water from 60 to 61 degrees Fahrenheit. This is a unit of measurement for energy, adopted in the United Stated and United Kingdom, and currently used instead of Watts (W). the consumption of an appliance per hour of use (the most frequently used is the kilowatt hour equal to 1000 Watts/h). The most interesting value is the watt hour i.e. Watts are used to measure the power of appliances and calculate energy consumption. Unit of measurement for power, used by the international system.
