BIL-y-uh-n/ˈbɪljən/
A billion is a thousand million (1,000,000,000) in modern UK and US use: £2 billion; billions of pounds. Million is a thousand thousand. Bn is the news abbreviation. Do not mix billion and million in a data description — examiners watch the noughts. Older UK “billion” once meant a million million; that meaning is obsolete in news.
Meaning
A thousand million (1,000,000,000).
Examples

Good to know
1 billion = 1,000,000,000. Abbreviation: bn. Do not confuse with million. Modern UK = US meaning.
