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.
A large unit of heat energy is called a British Thermal Unit (BTU). It is commonly used to measure the amount of heat energy needed to raise the temperature of one pound of water by one degree Fahrenheit.
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.

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 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.

Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
Heat is a form of energy and so the appropriate unit is a Joule.
The energy per unit charge is called the potentialdifference.
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.
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.
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.
