There are many more than two units in common use for energy.
Some of them are:
-- newton-meter
-- joule
-- foot-pound
-- calorie
-- watt-second
-- kilowatt-hour
-- horsepower-hour
Energy
The total energy input is 100 units. If 20 units are used for light energy and 30 units for sound energy, then the remaining energy would be 100 - 20 - 30 = 50 units. Based on the principle of conservation of energy, this remaining energy would likely be converted mainly into heat energy.
The most popular two heat energy units are: Calorie and BTU (British Thermal Unit).Both these units are obsolete. These days, allforms of energy are measured in joules.
If 20 units are used for light and 30 units are used for sound, then a total of 50 units are used for those two purposes. This means 50 units are left to be converted into heat. So, the number of units of electric energy converted into heat is 50.
Heat energy is energy, so its quantity can appropriately be described in terms of any convenient unit of energy. These include . . . -- calorie -- Calorie -- erg -- BTU -- Newton-meter -- Joule -- watt-second -- kilowatt-hour -- foot-pound
You can use the same units (energy units) for both.
The units for Gibbs free energy are joules (J) in the International System of Units (SI).
The units of energy in the equation Emc2 are joules (J).
You use the same units as for any other type of energy.You use the same units as for any other type of energy.You use the same units as for any other type of energy.You use the same units as for any other type of energy.
The energy needed to break a bond between two atoms is the called the bond energy. The SI units for bond energy are kJ/mol.
Energy has units of joules.
In the SI system the units are Joules. You can also use ftlbf (footpoundforce). For thermal energy use calories or BTU
