What is the basic practical unit of energy?

Answer 1

The unit of energy in the SI system is the [ Joule ].

In the 'customary' system, it could be the [ foot-pound ], the [ inch-pound ], etc.

Other useful energy units are the watt-second, the dyne-centimeter,

the horsepower-hour, and the Kilowatt-hour.

Answer 2

The standard metric system in use is the International System of Units, ("Système International d'Unités"), commonly abbreviated to the SI system. In this system, the unit of energy is the "Joule", named after the British physicist James Joule. One Joule is the energy trasnferred when a force of one Newton acts through a distance of one metre.

One Joule is exactly 10000000 ergs, or approximately 0.7376 foot-pound force.

Answer 3

The SI unit of energy is the Joule. It represents the amount of energy required to heat one gram of water by one degree Celcius. Other forms of energy are referenced to the Joule, for example, it is the amount of energy used with a 1 amp electrical current passing across 1 volt for one second.
