How much does it cost to run a 2.650w air conditioner per day or hour at 30c kwh?

Well, 2650w is 2.65kw, so it take 2.65kwh (kilowatt hours) per hour to run the heater. One kwh is 30c so 2.65kwh is 79.5c. It costs 79.5c to run the heater for an hour then multiply that by 24 to get the answer for a day. It comes to $19.08.

Well, that's what it costs in money, anyway. What it costs in terms of the environment is a whole other deal. You'd be better putting on a coat. :)

The cost of AC depends on various factors like:
1. Ac types
2.How long you use it every day
3.Price of energy or power
4. Air conditioner usage.
