Johannes,
Until you educate yourself on basic physics you will not be able to speak anything but gibberish on the topic... seriously, units and how to use them is covered in Jr. High... these are very basic things that are a pre-requisite to do any calculations.

If m = 2kg then I must multiply that by 2 and get 4 = 4*1 kg which is a square.

Why the extra factor of 2? Apparently you just felt like multiplying by 2 for some random reason...

Then this would indicate to me that 3.6*10^17 square meters would be radiated in one second if 2 kilograms of mass would be converted to energy.

That- in no way- makes even the remotest amount of sense- it is gibberish. It has no connection with reality.
The correct answer is ~1.79*10^17 joules is the energy equivalent of 2kg, this will be released over whatever period of time the conversion takes place.

This only takes into consideration of the energy from rest mass conversion.
The energy from the daughter elements are not calculated due to the fact that all of the 2kg would be converted to energy, the daughter elements would remain in the material that is left over.

This is- again- gibberish. If you convert 2 kg into energy, there are no 'daughter elements'... there would be no material left over from that 2 kg because you converted that material to energy.
You do not understand basic math, physics, dimensional analysis or basic reasoning, WHY do you insist on inflicting these delusional screeds upon us?

I mainly responded to demonstrate to newcomers here just how pointless it is- that has now been demonstrated. Every correction I have made here has been explained to you one way or another countless times before... you didn't listen then, and I fully expect that in 3 months you will be back here repeating the same errors.

You have had 20 years at this to learn so much- but here you are still, unable to grasp basic units... you really need to stop this nonsense.
