kWh to kW Calculator

How to Calculate Kilowatts (kW) from Kilowatt-Hours (kWh)

Converting kilowatt-hours (kWh) to kilowatts (kW) is a fundamental calculation in electrical engineering and power systems. This conversion is essential for understanding the relationship between energy (kWh) and power (kW) in electrical systems. Our calculator simplifies this process, but it's important to understand the underlying principles.

Calculation Formula

The formula to calculate kilowatts from kilowatt-hours is:

\[kW = \frac{kWh}{t}\]

Where:

• kW is the power in kilowatts
• kWh is the energy in kilowatt-hours
• t is the time in hours

Calculation Steps

1. Identify the energy in kilowatt-hours (kWh)
2. Determine the time period over which the energy was consumed (in hours)
3. Divide the kWh value by the time to get kilowatts

Example Calculation

Let's convert 10 kWh consumed over 2 hours to kW:

1. Identify the given values: \[kWh = 10\] \[t = 2 \text{ hours}\]
2. Apply the formula: \[kW = \frac{10}{2} = 5 \text{ kW}\]

Therefore, 10 kWh consumed over 2 hours is equal to 5 kW.

The height of each bar is proportional to its value, illustrating the relationship between kWh and kW in electrical systems. Note that the actual height difference may vary depending on the scale used.
