In science, the joule, the SI unit of energy, has largely replaced the BTU. Match consumed completely generates approximately 1 BTU). To raise the temperature of one pound of water by one degree Fahrenheit (Physical analogue: one four-inch wooden kitchen The British thermal unit (BTU or Btu) is a traditional unit of work equal to about 1055 joules. The "kwh" is a unit of energy, equivalent to the energy transferred or expended in one hour by one kilowatt (1000 watt) of power.Ībbreviation: kWh, kwhr. This is very important to keep in mind when purchasing an electric car.įor more science and physics calculators, click here.Conversion kwh to Btu or Btu to kWh - calculator convert kWh, BTU and joulesĮnter your value in one of the boxes and press enter, results are automatically calculated. This is because a more efficient and lighter car would require less power to move the same distance, and in turn, less KWH. An electric car with a lower KWH could still drive much further. The KWH of an electric car is usually specified as a metric to show off the power of a car, but in terms of range, it does not mean much. Since this power is consumed over time, the total energy can be calculated in kWh. This power is used to turn a motor, which turns an axle, which then turns the wheels to propel itself forward. Cars consume electricity in the form of power from batteries stored on the undercarriage. In the same way that appliances use electricity, so do electric cars. And what term is used with electricity? You guessed it, KWH. Electric cars are starting to appear more and more and you guessed it, they run on electricity. Electric cars have made a sudden surge in the last 5 years, due in part to the carmaker Tesla, which is delivering thousands of cars every week. 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. Now multiply that number by the cost per kWh of electricity to calculate the cost per week of your AC.Enter the hours and power into the formula to calculate KWH.We will assume a period of 7 days running 16 hours per day = 112 total hours. We will assume ours is a central air unit. A window unit likely runs closer to 500-1000 watts or less. An average central air unit likely runs at approximately 3500 watts.
