   Even cutting and pasting 

   2 mg c^2 -> kilotons TNT

   Into the to: box didn't work?  I'll have to look at my web logs and see
what you were trying to do.

   These are basically correct.  Your terminology is off, by the way.  The
"k" prefix is *always* written as lowercase.  Maybe that's where it was going
wrong, but the web-based interface would have told you that explicitly, and
how to fix it, and pointed you here:

   This is wrong.  Total conversion of 2 mg (1 mg antimatter, 1 mg matter) is
equivalent to about 39000 kilograms of TNT.

   Agreed.
