* In those countries that use the long scale (based on powers of a million) like Europe:
7 billion = 7 × (10^6)^2 = 7 × 10^12 = 7,000,000,000,000
* In those countries that use the short scale (based on powers of a thousand plus one) like USA:
7 billion = 7 × (10^3)^(2+1) = 7 × 10^9 = 7,000,000,000
The UK uses the same scale as the US.
7,000,000,000 is 7 billion
