Enter the power rating, time, and number of units into the calculator to determine the power consumption.

Home Power Formula

The following formula is used to calculate the power consumption of a home.

PC = P * T * U

Variables:

  • PC is the power consumption (kWh)
  • P is the power rating of the appliance (kW)
  • T is the time the appliance is used (hours)
  • U is the number of units of the appliance used

To calculate the power consumption, multiply the power rating of the appliance by the time the appliance is used, then multiply the result by the number of units of the appliance used.

What is a Home Power?

A Home Power refers to the energy or electricity used in a residential setting for various purposes such as lighting, heating, cooling, cooking, and powering electronic devices. This power can be sourced from the grid, renewable sources like solar panels or wind turbines, or backup generators. The management and efficient use of home power is crucial for energy conservation and reducing utility bills.

How to Calculate Home Power?

The following steps outline how to calculate the Power Consumption for a Home Power.


  1. First, determine the power rating of the appliance (P) in kilowatts (kW).
  2. Next, determine the time the appliance is used (T) in hours.
  3. Next, determine the number of units of the appliance used (U).
  4. Finally, use the formula PC = P * T * U to calculate the power consumption (PC) in kilowatt-hours (kWh).
  5. After inserting the variables and calculating the result, check your answer with a power consumption calculator.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Power rating of the appliance (P) = 1.5 kW

Time the appliance is used (T) = 4 hours

Number of units of the appliance used (U) = 2
