Enter the total power usage in (kW), the cost of electricity, and the hours of usage into the calculator to determine the kWH cost.

## 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)

## 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
