What this large number name generator does
Enter a whole number or a power of ten to identify its English short-scale and traditional long-scale name. Compare terms such as billion, milliard, trillion, nonillion, and googol without counting zeros by hand.
How to use it
- Enter a 1 followed by zeros, such as 1000000000, or scientific notation such as 1e9.
- Read the scientific notation and number of zeros.
- Compare the modern English or US short-scale name with the traditional European long-scale name.
Examples
- 109 is a billion in the short scale and a milliard in the long scale.
- 1012 is a trillion in the short scale and a billion in the long scale.
- 10100 is called a googol in both scales.
Why number names can differ
Most modern English uses the short scale, where each new -illion is 1,000 times the previous one. Some languages and traditional European usage use the long scale, where the same words can refer to different powers of ten. For important figures, include digits or scientific notation as well as the written name.
Frequently asked questions
How do I find the name of a large number?
Enter a whole number beginning with 1 and followed by zeros, or use scientific notation such as 1e12. The generator shows the corresponding name when it is included in the reference table.
What is the difference between billion and milliard?
In modern English short scale, 10^9 is a billion. In traditional long-scale usage, 10^9 is a milliard and 10^12 is a billion.
How many zeros are in a nonillion?
In the modern English short scale, a nonillion is 10^30, or 1 followed by 30 zeros. In the traditional long scale, nonillion can refer to a different power, so include digits when precision matters.
