What is 10 million in billions?

Answer 1

Depending upon where you are:

• In those countries that use the long scale (based on powers of a million), like Europe:

1 billion = (10^6)^2 = 10^6 × 10^6 = 10^6 million = 1,000,000 million = 1 million million

→ 10 million = 10 million ÷ (10^6 × 1 million) billion = 10^-5 million = 0.00001 billion

• In those countries that use the short scale (based on powers of a thousand plus one), like USA:

1 billion = (10^3)^(2+1) = 10^9 = 10^3 × 10^6 = 10^3 million = 1,000 million = 1 thousand million

→ 10 million = 10 million ÷ (10^3 × 1 million) billion = 10^-2 billion = 0.01 billion
