How much is a trillion?

Answer 1

Under the current "short scale" of numeration, a "trillion" is one thousand billion or 1012. (The superceded "long scale" used names that increased by a factor of one million, making the old billion 1012 and the old trillion 1018.)

Answer 2

A trillion is commonly 1,000,000,000,000 or one million million. So half a trillion would be 500,000,000,000 or five hundred thousand million.

Less commonly, but still accepted in some places, a trillion is 1,000,000,000,000,000,000 or one million million million. So half a trillion would be 500,000,000,000,000,000 or five hundred thousand million million.

Answer 4
