Cars consume electricity in the form of power from batteries stored on the under carriage. It's really important to take and regularly send accurate gas meter readings to your energy supplier – if you don’t know how to use your meters correctly, you can’t be sure you’re getting billed correctly. Enter the hours and power into the formula to calculate KWH. How to do a self meter read. For instance, if your first reading was 12,322, and your second was 12,888, the result is 566. At 300 watt-hours per day, you would be consuming 0.3 kWh per day with your television alone. For light bulbs this is almost always shown directly on the package in watts. Multiply power by times yields energy, and that’s why KWH is considered a derived unit of energy. In the menu go to Usage, then to “Read my own meter”. This could be over it’s life time, or over a shorter period like a day. For example, if you have 30,000 Btu, divide 30,000 by 3,413 to get 8.7899 kWh. Energy Bill Calculator. A kilowatt hour is simply 1,000 watts of electricity used for one hour. Multiply this by 30 to work out your average electric bill. kWh meter. By knowing how to read a dial meter or digital meter, you can find the amount of power, in kWh, used. Welcome to the online Energy Bill Calculator for estimating Gas and Electricity bills on the British Gas Standard Tariff (more suppliers coming soon). You will however pay for gas using a price per kWh. Here's how to convert cubic feet (ft3) to kWh from your gas meter reading. The term Kilowatt hours has become more and more prevalent over the last 5-10 years, and that’s mostly due to one thing…cars. If you have a two rate meter or economy 7 meter then press 6 on the keypad until you see ‘IMP R01’ followed by 8 digits. Kilowatts, abbreviated kW, are a measure of electric power. A watt is a measure of power, and hours is a measure of time. Phone calls: Calls may be monitored and/or recorded for security, quality or training purposes. Other questions we get asked. To convert your gas meter readings to kWhs feel free to use our free gas meter reading calculator. More specifically, electric cars. This quick view reviews reading the digital electric meter at home and making the two calculations needed to think about energy usage. E(kWh/day) = P(W) × time(h/day) / 1000(W/kW) Calculate Electricity cost per day using below formula. Divide the electrical meter reading in Btu by 3,413 Btu per kWh to convert to kWh. Learn how to read your electricity meter accurately in this short video. 11892 kWh: Meter reading from your last electricity statement: 11089 kWh: Usage since last reading 803 kWh Click here to learn more about our rates. The energy consumption is calculated by calculating the difference of the counter's reading in the specified period. Mark Kennan is a writer based in the Kansas City area, specializing in personal finance and business topics. Let’s take an example of trying to calculate the KWH usage of a light bulb. It’s not officially recognized by the SI unit system, although the derived unit of joules is. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. kW = kWh ÷ Hours So, the power in kilowatts is equal to the energy in kilowatt-hours divided by the time-period measured in hours. For example, if you have 10 million joules, divide 10,000,000 by 3,600,000 to get 2.78 kWh. If your meter is in cubic feet, 1 cu ft is 0.028 cu m. 0 And average central air unit likely runs at approximately 3500 watts. University of Wisconsin Stevens Point: What is Energy?
