As with most other measures used in ''[[Star Trek]]'' there are no direct conversions to real world measures given. However, given the units of measure is in kilograms and the technical manual figures provided, a hypothetical calculation of an isoton is as follows:
 
 
A ton of TNT (a metric ton = 1000 kg) is 4.184 × 10^9 Joules
 
A megaton of TNT is 4.184 × 10^15 Joules
 
c = 299 792 458 m/s
 
Using the equation for mass-energy conversion:
 
E = mc2
 
E = m*89875517873681764
 
 
With a standard Photon torpedo being 1.5kg matter and 1.5kg antimatter, this totals 3kg of reactants. Thus:
 
 
E = 3*89875517873681764
 
E = 269626553621045292 Joules
 
 
According to the technical manual, a standard photon torpedo yields a theoretical maximum of 25 isotons. Using the above theoretical maximum assuming all matter/antimatter is reacted, divided by the theoretical maximum for the torpedo's yield:
 
 
269626553621045292 / 25 = 10785062144841811.68 Joules/Isoton
 
 
This amount divided by the amount of energy in one megaton:
 
 
10785062144841811.68 / 4.184 × 10^15 = 2.578 megatons
 
 
Therefore, 1 isoton = 2.578 megatons.
 
 
The ‘usable’ yield from a photon torpedo is 18.5 isotons according to the tech manual, which is roughly 47.693 megatons,
 
while the theoretical maximum yield of 25 isotons is roughly 64.44 megatons.
 
A quantum torpedo has a yield of about 52 isotons, which is roughly 134 megatons.
 
 
 
In ''[[Star Trek: The Next Generation Technical Manual]]'' a figure of 1,5kg of antimatter is given as the maximum warhead material of a photon torpedo. (pg. 129) Using standard physics calculations a direct 1:1 explosion would equal to about 64.4 megatons.

An isoton was a measure of both mass and explosive yield used by at least Federation, Dominion, Borg and Malon science during the 24th century and Kyrian in the 31st century.

Comparative list of measure

Isogram = 1 one-millionth of an isoton

Isoton

  • 200 isotons was the explosive yield of a photon torpedo with a class-6 warhead. (VOY: "Scorpion, Part II")
  • 6 billion isotons of antimatter waste was produced daily, in 2375, by the Malon civilization as an industrial byproduct. (VOY: "Night")

Appendices

Background information

According to the Star Trek: Deep Space Nine Technical Manual, 25 isotons is the maximum theoretical yield of a matter-antimatter reaction in photon torpedoes and that quantum torpedoes have at least twice the yield at 50+ isotons. (pg. 85) These figures are not compatible with the canonical statements in "Scorpion, Part II" of 200 isotons as the yield of a class-6 photon torpedo warhead and in Star Trek Into Darkness of 320 isotons as the yield of a class-12 photon torpedo. As with most other measures used in Star Trek there are no direct conversions to real world measures given.

In Star Trek: The Next Generation Technical Manual a figure of 1.5 kg of antimatter is given as the amount of warhead material carried by a standard photon torpedo. (pg. 129) Using standard physics calculations a direct 1:1 detonation would generate 64.4 megatons of energy. Warhead materials are however premixed to achieves the level of destructive force of an antimatter pod rupture containing 100 cubic meters of antideuterium. (pg. 69) Antimatter is stored as liquid or slush on starships. (pg. 68) Density of mere liquid antideuterium is around 160 kg per cubic meter. According to this comparison the destructive effect in the high annihilation rate energy release would be comparable to the effects of a 690 gigaton blast. Furthermore it is not clear if the 1.5 kg should be compared to the 200 - 320 isoton figures given on screen later on, or the 25 isoton figure given in the Star Trek: Deep Space Nine Technical Manual reference book to make a conversion.
