The number "one million" has six zeros after a one and before the decimal point. It is written out like this: "1,000,000." This is true in both the short-scale and long-scale naming systems.
These two systems are used to name large numbers. While one million is the same in either scale, the short scale and the long scale diverge with numbers greater than a million. For example, 1 billion has nine zeros in the short scale and 12 zeros in the long scale. Therefore, a billion in the long scale represents a larger number than a billion in the short scale. The short scale is found in American, Canadian and modern British usage. The long scale is found in continental European and older British usage.
