Yeah is a lot!! already know about it! All this info is in the Book  Godzilla 1954-1999 Super Complete Works

Normal Atomic Breath was stated to have a temperature of 500,000 Celcius degrees in the Godzila Super Complete Works Book.

The same book also talks about the Spiral Breath A somewhat more powerful form of Godzilla's regular Atomic Ray which was used to defeat King Ghidorah. But don't provide any Temperature Info as the Red Spiral Ray.

[[1]] Another temperature, huh? Cool. We can actually gauge normal Heisei Godzilla's power compared to his red spiral ray forms now.

I read on another forum that the normal atomic breath was stated to be "less than half as powerful" as the red spiral ray, but the comment didn't state a temperature. I guess it should have really said "less than half as hot." Thermal radiation emitted by a body is proportional to the fourth power of temperature, so half the temperature actually means 1/16th the energy. That means the red spiral ray used against MechaGodzilla II is more than 16 times stronger than the normal atomic breath.

Actually, a quick plug-and-chug using an online calculator gives a 1,200,000 Kelvin beam 33 times the power output of a 500,000 Kelvin beam assuming all other parameters are the same.

(Also, a 500,000 K atomic breath would release the energy equivalent of hundreds to thousands of Megatons of TNT (hundreds of millions to billions of tons of TNT) depending on the length of the beam and its duration, so Godzilla really does live up to his reputation as a walking nuclear apocalypse.)

By the way, earlier in this thread I mentioned I made a calculation for Zilla Jr.'s atomic breath's temperature during one of its best feats. I had to re-do the calculation to get a more accurate result.

To create a (realistically-sized) warm front in such a short amount of time, his atomic breath would have had to reach temperatures well above 11,158,000 K, making Zilla Jr.'s atomic breath at its strongest more than 9 times hotter than the red spiral ray used against MechaGodzilla II.

Actually, I was thinking of the rage attack from Save the Earth. It was the "Finishing Breath" used by 90s Godzilla.

EDIT: Now I'm being told that the Showa-era atomic breath has a stated temperature of 100,000 degrees C.

(A 100,000 Kelvin beam would have an energy output of hundreds of thousands to millions of tons of TNT, significantly lower than the Heisei-era atomic breath.) Nice theory.
