I played with regexp() some, but, could not find a pattern that matched just the characters within the parens.

I suggest matching from a paren, continuing along everything that is NOT a paren:

[s, e, te, m, t, nm, sp] = regexp(str,"[(]([^)]*)")

t =
{
  [1,1] =
  {
    [1,1] = 10^15 kg
  }
  [1,2] =
  {
    [1,1] = km
  }
  [1,3] =
  {
    [1,1] = kg/m^3
  }
}
