Frequently Asked Questions
What energy units are supported by this converter?
Our tool supports a wide range of energy units, including Joules (J), kilojoules (kJ), megajoules (MJ), gigajoules (GJ), watt-hours (Wh), kilowatt-hours (kWh), megawatt-hours (MWh), gigawatt-hours (GWh), calories (cal), kilocalories (kcal or Cal), British Thermal Units (BTU), foot-pounds (ft-lb), and electronvolts (eV).
How accurate is the Energy Converter for scientific and engineering calculations?
Our online Energy Converter uses precise, standard mathematical conversion factors, ensuring high accuracy suitable for physics, chemistry, engineering calculations, and technical applications requiring reliable energy conversions.
Is the Energy Converter tool completely free?
Yes, our Energy Converter is 100% free to use online. There are no costs, subscriptions, or limitations on the number of energy conversions you can perform.
How do I convert kilowatt-hours (kWh) to Joules?
To convert kilowatt-hours to Joules, select 'kilowatt-hours (kWh)' as your 'Convert From' unit and 'Joules (J)' as your 'Convert To' unit. Enter the value in kWh, and the converter will instantly show you the equivalent in Joules. (1 kWh = 3,600,000 Joules).
Can I use this converter for nutritional Calories?
Yes, you can convert nutritional Calories (often capitalized as Cal) to other energy units like Joules or kilojoules. Note that 1 nutritional Calorie (Cal) is equivalent to 1000 small calories (cal) or 1 kilocalorie (kcal). Our tool handles this distinction.
What is the difference between energy and power?
Energy is the capacity to do work or produce heat, representing a total amount (e.g., the energy stored in a battery). Power is the *rate* at which energy is transferred or used (e.g., how quickly a device uses energy). Power is energy per unit time (e.g., Joules per second = Watts). This tool converts units of *energy*, not power.
