How to convert millions to billions
billions = millions ÷ 1,000
millions = billions × 1,000
A million is 10⁶ and a billion is 10⁹, so a billion is three powers of ten, or 1,000 times, larger. Move the decimal point three places left to go from millions to billions.
Number names

- Million: 1,000,000 (10⁶)
- Billion: 1,000,000,000 (10⁹)
- Trillion: 1,000,000,000,000 (10¹²)
Worked examples
- A company with $6,600 million in revenue: 6,600 ÷ 1,000 = $6.6 billion.
- A population of 1,400 million: 1.4 billion people.
- A budget of $0.75 billion: 0.75 × 1,000 = $750 million.
