Amps to Kilowatts (kW) Electrical Conversion Calculator, Capacitance to Charge Electrical Conversion Calculator. The higher the wattage is, the more power and output from the appliance. I have a small 800W max space heater in the garage. current = 10A. Watt’s Law states that current = power ÷ voltage. For three-phase AC circuits where the line to line voltage is known, the formula to convert watts to amps is: The current I in amps is equal to the power P in watts divided by the line to line voltage V in volts multiplied by the power factor PF multiplied by the square root of 3. Ten feet give you 60 watts, so divide that by your supply voltage to get the current in amps. For AC power supply, amps are equal to watts divided by power factor times volts. So, below are ‘back of a napkin’ calculations. All Rights Reserved. A block heater will use as many watts as is stamped on the unit. how many amps does a water heater draw I have a 220 volt water heater with I believe a 1500 watt elements, how many amps does it draw ?? (For example: 30 minutes per day is 0.5) Power Use (Watts): Enter the average power consumption of the device in watts. Click to see full answer. It is not possible to convert watts directly to amps without also knowing voltage or resistance. The Xantrex 813-5000-UL power inverter is an excellent performer in the industry with its ability to supply 5000 watts of power in a single output. Ed Janowiak. Here you go! Because 1 kilowatt is equal to 1,000 watts, it is possible to use the formulas above to also convert kW to amps, but watts need to be converted to kW first. Given this, to find amps given power and voltage use the following formula: Thus, the current I in amps is equal to the power P in watts divided by the voltage V in volts. Most of the time it works fine, but occasionally it will trip the 15 amp breaker it's on. amps = 1000W / 12V = 83.333A. The formula will solve for current in amps. Part numbers, wattage and installation instructions for each. For three-phase AC circuits where the line to neutral voltage is known, the formula to convert watts to amps is: The current I in amps is equal to the power P in watts divided by the voltage V in volts multiplied by the power factor PF multiplied by 3. For example, find the amperage of 1200 watts at 120 volts, current = power ÷ voltage Plus, check out the formula for the conversion with example calculations. Use our electrical conversion calculators to calculate electrical properties given other known values. Are You Planning a Home Improvement Project? If you’re unsure what the power factor is then a power factor calculator can help. They are not all the same. How Many Watts Does An Electric Space Heater Use? Therefore, it is important to know how much electricity the alternative, infrared heaters, use then weigh your options.Like In other words, the current I in amps is equal to the power P in watts divided by the voltage V in volts multiplied by the power factor PF.
