After that take difference of the two readings and multiply it by unit rate of electricity to get the actual amount of electricity bill. If you want to cross verify your electricity bill, you just need to take the kWh reading of your energy meter at the beginning and end of month. Therefore, the total electricity bill for one month If the cost of per Unit electrical energy is $R, then the total amount charged for the consumption of electrical energy is given by the multiplication of $R and number of Units consumed. Since, 1 Unit Electricity 1 kWh 1 kW x 1 Hour 1000 W x 3600 seconds 3. 1 kWh is the amount of energy consumption by 1 kW load in one hour. 1 kWh (kilo watt hour) and 1 Unit are same. The rate of electricity is given in terms of per unit cost. It is basically measurement unit of electrical energy consumption in Joule. Total Units of electrical energy consumed = (y-x) Units Then, total kWh consumed for that month = (y-x) Let the initial reading of energy meter at the beginning of month = x kWhįinal reading of energy meter at the end of month = y kWh The difference between the two consecutive kWh readings of energy meter taken over a time period gives the number of Units of electrical energy consumed during that period. You can easily see the power consumption in kWh in your energy meter. The power consumption of electrical appliances is measured in term of Units. The amount of time and power that each appliance is used varies significantly between households, so for the best results, adjust the usage for each appliance to most accurately reflect your personal usage. Thus, when we talk of power consumption calculation, we basically mean to calculate the energy consumption for a certain time period. Electricity Calculator Use the calculator below to estimate electricity usage and cost based on the power requirements and usage of appliances. Power consumption is basically the energy consumption. Tip: if you want a rate including fixed fees, enter the total charged including. Enter the total amount charged for electricity. Date / name of bill (optional) Total amount charged for electricity in Rands (required). Work out how much you are being charged for electricity per kWh or unit. The bill amount is based on the cost of 1 Unit Electricity and the number of Units consumed. Simple Electricity Calculator: Cost per kWh calculator. You might have seen the electricity bill of your home. What is your average Electricity Cost : Rs. Therefore, 1 Unit Electricity is equal to 3.6×10 6 Joule of electrical energy consumption. Choose any one of the following Total Roof Top Area (OR) Solar Panel Capacity you want to install (OR) Your budget 2.
