Ten-thousand trillion has 16 zeros; this is also known as ten quadrillion

One trillion = 1,000,000,000,000 (12 zeros)

Ten trillion = 10,000,000,000,000 (13 zeros)

One-hundred trillion = 100,000,000,000,000 (14 zeros)

One-thousand trillion = 1,000,000,000,000,000 (15 zeros) (or one quadrillion)

Ten-thousand trillion = 10,000,000,000,000,000 (16 zeros) (or ten quadrillion)

That assumes the short scale (based on powers of a thousand plus 1) where thousand-trillion is not a normal moniker for a number - it would, as the answerer points out, be called ten quadrillion.

The long scale (based on powers of a million) does use the moniker thousand-...illion for numbers (which are alternatively called ..illiard, eg 1000 million = 1 milliard, 1000 billion = 1 billiard, etc). In this case:

10 thousand trillion = 10000 x (106)3 = 104 x 1018 = 1022 and so has 22 zeros.
