Under the **short scale**, the one American English uses and the one UK official figures have followed since the 1970s, **one billion equals one thousand million (1,000,000,000)**, or nine zeroes if you’re counting. That works out to: - 1 billion = 1,000 million - 1 million = 0.001 billion To put that in perspective: earning $100,000 a year, it would take **10 years** to reach $1 million, and roughly **10,000 years** at that same pace to hit $1 billion. ### How to convert million to billion **Short-scale conversion (US / UK modern usage)** Just divide your million figure by **1,000**. Five million dollars comes out to 0.005 billion, and one thousand million lands exactly on one billion. ### How to convert billion to million **Reverse conversion** Multiply your billion figure by **1,000** instead. A $3.2 billion acquisition, for instance, comes out to $3,200 million. ### How many zeros in 1 billion? On the short scale, **1 billion equals 1,000,000,000**, or **nine zeros**. The UK historically used a long-scale billion (one million million, twelve zeros), but government statistics have since switched to the thousand-million definition, lining up with the US and most international finance reporting. ### Million to billion chart MillionBillionMillionBillion 1 million0.001 billion20 million0.02 billion 2 million0.002 billion30 million0.03 billion 5 million0.005 billion50 million0.05 billion 10 million0.01 billion100 million0.1 billion 100 million0.1 billion1,000 million1 billion ### Billion to million chart BillionMillionBillionMillion 1 billion1,000 million10 billion10,000 million 2 billion2,000 million20 billion20,000 million 5 billion5,000 million50 billion50,000 million ### What does a billion look like?
