Calculation Results

Calculation Formula

Energy (kWh) = Power (W) × Time (h) / 1000

Where:
Power (W) - The power of the electrical appliance in watts.
Time (h) - The usage time of the electrical appliance in hours.
Energy (kWh) - The energy consumption of the electrical appliance in kilowatt-hours.

Learn how to use the Kilowatt per Hour Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the power of the electrical appliance in watts in the "Power (Watts)" field.
  2. Enter the usage time of the electrical appliance in hours in the "Usage Time (Hours)" field.
  3. Click the "Calculate" button to calculate the energy consumption in kilowatt-hours.
  4. The result will be displayed in the "Energy Consumption (kWh)" field.

Example

If you have a 1000W (1kW) heater and use it for 5 hours, the energy consumption would be:

Energy (kWh) = 1000W × 5h / 1000 = 5 kWh

Principle Explanation

The Kilowatt per Hour Calculator calculates the energy consumption of electrical appliances based on the power and usage time. The formula used is:

Energy (kWh) = Power (W) × Time (h) / 1000

This formula helps in understanding the energy consumption of electrical appliances, which is useful for managing electricity bills and making energy-efficient choices.
