   Most of the calculation side can be done with equations that can be found on   
   Atomic Rockets.  No doubt we can also discuss calculations here, but it may   
   well be faster for you to look into the article on each of the areas you are   
   interested in to compile    
   your arsenal of formulae.     
      
   That said, I've been doing quite a lot of worldbuilding, myself, and there are   
   a few relatively minor points on which I would tend to distance myself from   
   Atomic Rockets.  The biggest, in my mind, is the way damage is always measured   
   purely in the energy    
   theoretically delivered to the target.  This is really mostly applicable   
   regarding kinetic weapons, in my mind.     
      
   Just because kinetics will begin carrying more energy per kilogram than a   
   given high-explosive compound or mixture does NOT mean high-explosive fillers   
   are suddenly useless.  Not all joules are created equal--or, more accurately,   
   not all joules will be    
   delivered to the target equally.     
      
   Just because a solid piece of tungsten or depleted uranium moving at a certain   
   velocity relative to its target carries much more energy than is needed to   
   perforate its hull does not automatically guarantee that it will not simply be   
   overmatched for its    
   target and pass straight through, failing to deliver much of its energy on   
   impact.     
      
   That notion isn't really related to the spreadsheet.  I just feel like that's   
   something to consider for general world building.
