Incredible: a significant subset of Firebug, also compatible with IE and Opera, in a bookmarklet.

Use self-raising flour instead; surprisingly tasty.

According to his calculations: 1TByte = 8Tbits
1 punch card =960 possible holes(bits), 12 rows X 80 columns.
8Tbits / 960 = 8,333,333,333 punch cards

A punch card is 7.375" X 3.25" X .007" = 0.1677812 cubic in
1 cubic ft = 1728 cubic in = 10,299 cards
8,333,333,333 cards / 10,299 cards = 809,140 cubic ft

and so 809,140 cubic ft x 12 = 9,709,680 cubic ft
(1 cubic mile = 147.2 billion cu ft.)

Glad to be of help.
