person who has a net worth of at least one billion (1,000,000,000) units of a given currency
Would a 900,000 pound net worth person be an American billionaire if they exchange currency June 2020?
The exchange rate in June of 2020 between dollars and pounds is 1 Euro= 1.23 dollar. 900000 pounds is equal to about 1,107,000.00
What is the minimum amount one must have to be called a billionaire? As of  June 2020, how many dollars make a pound? Is #2 times 900000 at least equal to #1?
