1,000,000,000,000
1,000,000,000,000 is one trillion on the short scale, and 10¹² exactly.
Where 1,000,000,000,000 fits
Why 1,000,000,000,000 is special
On the long scale still used across much of continental Europe, 10¹² is a billion, not a trillion — the two conventions disagree by a factor of a thousand at exactly this number. It is also where this catalogue stops computing: above 10¹², factorising a value on request would cost more than the page is worth, so a larger number keeps its exact identity and loses its mathematical analysis.
