Joule

A joule is a unit of energy, named after scientist James Prescott Joule. An explosion of 4.184 gigajoules is the equivelant amount of energy to that released by one metric ton explosion.

Comparative list of energies

Millijoule = 0.001 joule

• Tom Paris used a cardio-stimulator to cajole the heart of Brin's son to life. Although the initial charge of 3 millijoules was unsuccessful, the second charge set at 5 millijoules was successful. (VOY: "Friendship One")

Kilojoule = 1 thousand joules

• The deflector shield protecting the Lysian Central Command had an output of 4.3 kilojoules and could have easily been taken out with a single photon torpedo. (TNG: "Conundrum")

Megajoule = 1 million joules

• The disruptor capacity of 24th century Lysian destroyers were rated at 2.1 megajoules. (TNG: "Conundrum")

• In an attempt to activate a scanner discovered in the Gamma Quadrant, Data suggests transferring 20 megajoules of energy from the dilithium chamber into the plasma inputs of the device. (TNG: "Birthright, Part I")

Gigajoule = 1 billion joules

• The Breen CRM 114 was capable of cutting through shields with an output of up to 4.6 gigajoules. (DS9: "Business as Usual")

• 22nd century Earth Starfleet phase cannons were rated for a maximum power output of 500 gigajoules. (ENT: "Silent Enemy")
