Joules (J):
Description: It is the base SI unit of energy. It tells work done in terms of the force in newton over a distance measured in a meter.
Conversion Factor: 1 (Base Unit)
Use it in: Calculation of energy, work, or heat encountered in physics, engineering, and other scientific calculations.
Kilojoules (kJ):
Description: 1 kilojoule = 1000 joules. This unit is mainly used to represent higher values of energy
Conversion Factor: 1000.000000
Common Applications: Nutrition labeling (calorie value of food), chemistry and physics.
Calories (small) (cal):
Definition: A small calorie (gram calorie) is the quantity of energy that is needed to raise the temperature of one gram of water by one degree Celsius.
Conversion Factor: 4.184000
Common Applications: Nutrition science, content of energy from foods, and chemistry.
Kilocalories (large) (kcal):
Description: A kilocalorie (also known as a large calorie or food calorie) is the energy needed to increase the temperature of one kilogram of water by one degree Celsius.
Conversion Factor: 4184.000000
Common Applications: Content of energy in food (frequently just "calories" on packages).
Watt-hours (Wh):
Description: Watt-hour is a unit of energy equivalent to watt of power spent during one hour of time.
Conversion Factor: 3600.000000
Watt-hours (Wh):
Definition: A Watt-hour is a measure for the energy that is supplied by one watt for one hour, or a power of one watt for a time of one hour, and it is typically used to express electrical energy usage
Conversion Rate: 1.000000.000000
Common Applications: Power consumption, energy consumption, battery size, and electricity usage
Kilowatt-hours (kWh):
Definition: A kilowatt-hour is the equivalent amount of 1,000 watt-hours. It is frequently employed in the calculation of electrical energy usage
Conversion Rate: 3600000.000000
Common Applications: Household electricity consumption, cost of energy, large power consumption
Electronvolts (eV):
Definition: An electronvolt is a unit of energy, equal to the energy gained by an electron when it moves through an electric potential difference of one volt.
Conversion Factor: Extremely small; mainly applicable to the atomic and subatomic level.
Applications: Particle physics, quantum mechanics, and chemistry
