Calorie is the largest which equals to 4.16 joule. Of course calorie is not SI unit. It was used in olden days. Any way we use it till date in case of bio energy derived right from food.
Heat is molecular motion; the units are BTU and calories.
... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.
Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
The energy per unit mass required to complete a phase change is called the latent heat. It represents the energy needed to change the state of a substance without changing its temperature.
Quite simply, because heat is also a form of energy. It has been found that a certain amount of mechanical energy is equivalent to a certain amount of heat energy; it makes sense to use the same unit for all kinds of energy.

... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.
Heat is a energy form.So unit of heat is the same as energy
Work is transfer of energy; thus, the unit of work is the same as the unit of energy. The SI unit is called "Joule".Work is transfer of energy; thus, the unit of work is the same as the unit of energy. The SI unit is called "Joule".Work is transfer of energy; thus, the unit of work is the same as the unit of energy. The SI unit is called "Joule".Work is transfer of energy; thus, the unit of work is the same as the unit of energy. The SI unit is called "Joule".
the energy unit is called joules
The unit for energy is the joule. That's also the unit for work and for heat - both of which refer to energy transfers.
Heat is a form of energy and so the appropriate unit is a Joule.
Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
The energy per unit charge is called the potentialdifference.
Energy is measured in joules. Sometimes the older unit "calorie" is used instead - this is a unit defined on the basis of heat, but it is still a unit of energy.
The energy per unit mass required to complete a phase change is called the latent heat. It represents the energy needed to change the state of a substance without changing its temperature.
Heat is a form of energy. In terms of kinetic theory it can be defined asthe sum of kinetic energy of molecules in a sample of a substance.-- Its SI unit is the Joule.-- Its CGS unit is the erg = 10-7 joule.Comment'Heat' is energy in transit between a warmer body and a cooler body. The definition given in the original answer is for 'internal energy', not heat.
