15/6/17 Billion, Trillion, and Milliard
The names of large numbers can be ambiguous. In the U.S. a billion is a thousand million (9 zeros), but in most other countries a billion is traditionally a million million (12 zeros, which is what Americans call a trillion).
The British term for what Americans call a billion is a milliard, but that word has almost disappeared. The American meanings are now widely accepted in international finance and commerce.
