What this converter does

A billion is 1,000,000,000 (10⁽) in the short scale used in the US, UK, and most of the world today. A trillion is 1,000,000,000,000 (10¹²), one thousand billion, the next scale step up used for the very largest economic and scientific figures.

Where trillion-scale figures actually come up

Unlike million and billion, which appear constantly in everyday business and finance, trillion-scale numbers are mostly reserved for national and global economic figures, government debt, GDP of large economies, and total global market capitalizations, contexts where getting the scale wrong by a factor of 1,000 would be a significant misreading of the underlying figure.
