To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
To calculate the cost, you need to know the cost per kilowatt-hour (kWh) from your utility provider. Multiply the kWh of the shower unit (9 kWh) by the duration (0.5 hours) to get the total energy used. Then multiply this by the cost per kWh to get the total cost.
To calculate the cost, you need to know your electricity rate. If the rate is $0.12 per kWh, then using a 5-watt device for 24 hours a day for 31 days would consume 3.72 kWh (5 watts * 24 hours * 31 days / 1000) and cost around $0.45 (3.72 kWh * $0.12).
About 11.75 cents per kWh for residential use (7.53 cents/kWh for industrial), as of September 2010:
The average KWH is 0.1099 per hour. In order to determine how an electric bill is calculated for a home is to use an online calculator. This will explain how much electricity is used by different things in your home.
Coal cost about $o.o54 cents per kwh
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.

The energy cost depends on the size of the system. Large concentrated systems cost $0.10-$0.15 per kWh. Medium and small scale systems can cost from $0.25-$0.50 per kWh, when averaged.
A full charging cycle of the Segway batteries consumes 1.04 kWh. At a winter, residential rate of .085, this computes to $ 0.0884 ( 8.84 cents ) per full charge. At a summer rate of .105, the cost is $ 0.1092 . Round it off to 10 cents per charge.
To calculate the cost, you need to know the cost per kilowatt-hour (kWh) from your utility provider. Multiply the kWh of the shower unit (9 kWh) by the duration (0.5 hours) to get the total energy used. Then multiply this by the cost per kWh to get the total cost.
Divide the dollars per kWh by 3,412.14163
A 60W bulb will use 60W X 1 hour / 1000. this will give you the KWh - the units your electricity company uses to charge you.So 60 X 1 =6060/1000 =0.060 Kwh
4-8 cents
