Fraid you did - it's TERA.
Another thing ... can I ask that terms like billion and trillion are
avoided as much as possible, as they differ in the USA and elsewhere?
(In the US, 1 billion = 10^9 and 1 trillion = 10^12; other places it's
1000 times this amount). (Except in France, who for some reason went for
a Russian television system and an American counting system!).
