Calculate the watt-hours for each electronic device. For each device, multiply the device watt rating by the average number of hours the devices is on for the set time period. For example, if your PC was rated at 20 watts and was on three hours per day, it would use 60 watt-hours o...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.
You can use either of the following equations to calculate power in watts, provided all quantities are expressed in in MKS (meters, kilograms, seconds) metric units. P=F×v P=Wt If you do your measurements on the CGS (centimeters, grams, seconds) system, force is expressed in dynes and ...
knowing how to convert amps to watts can help. Many household appliances have power ratings in watts, but the current they draw in amps is often listed instead. By understanding how to calculate watts from amps, you can easily figure outhow much energy your devices are using. ...

Here’s how to calculate: Let’s say you have a 55” LED TV that uses80 wattsper hour and you watch TV for5 hoursa day. Next, you need to know your local electricity rate. In South Africa, electricity rates can vary significantly depending on where you live, whether you’re supplied...
How to calculate the air conditioning power for a given surface area?When it comes to buying a domestic air conditioning system, the same question always arises: What power is the right one? How many frigories or watts do I need per square metre? Depending on the answer, the investment ...
Not all Watts used by a fixture go to lighting; some are lost in the form of heat. With that in mind, here’s how to calculate Lumens per Watt: Here, we use this formula… Lm/W = Lumens / Watts For example: If you have a standard 15W LED fixture that produces 1500 lumens of ...
To replenish the energy used in the extended example above (139.1 amp hours) you would need an array of panels totaling 500 watts. We arrive at this calculation from the guideline that each panel will produce about 30 amp-hours per day in ideal conditions. If using five 100 watt panels ...
We can calculate how much impact this will have on our monthly electricity bill. For that, we need to know the price of electricity. Let’s presume that we run a 1,000 W air conditioner continuously for 1 month, with the average price of electricity being $0.1319 per kWh. ...
