kW to kWh Cost Conversion
The following formula is used to convert a power usage (kW) into the cost (kWh cost).
kWh-c = TC / (P*T)
- Where kWh-c is the kWh cost ($/kWh)
- TC is the total cost of the electricity used ($)
- P is the power usage (kW)
- T is the total time of usage (hr)
To calculate the kWh cost, divide the total cost by the product of the kW and time of usage.
What is kWh Cost?
A kWh cost is a metric used to describe the total cost of using electricity per kWh.
A kWh, short for kilowatt-hour, is a metric that describes power usage per hour.
Example Problem
How to calculate kWh cost from kWh?
The first step in calculating a kWh cost from kWh is to determine the total cost of the electricity/power usage over a period of time.
For this example, the total cost of electricity was $100.00.
Next, determine the total power consumption that the device or household was running at on average for the time period.
In this case, the entire household was averaging a power consumption of 10kW.
Next, determine the total number of hours that the cost and power usage occurred during.
For this example, the power usage was for a full 24 hours.
Finally, calculate the kWh cost using the formula above:
kWh-c = TC / (P*T)
kWh-c = $100 / (24*10)
kWh-c = $.416/kWh
