## 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
