How many 0 in 2.8 billion?

Answer 1

In Britain, a billion was once one million times one million, so 2.8 billion would be = 2,800,000,000,000 therefore, 11 zeroes.

In American it was one thousand times one million, so 2.8 billion would be = 2,800,000,000

therefore, 8 zeroes.

For sometime now, the UK has adopted the American standard that one billion is 1,000 x 1,000,000

which equals 1,000,000,000
