This page uses the modern English short scale: million = 10⁶, billion = 10⁹, trillion = 10¹² and quadrillion = 10¹⁵. The numerical relationship is the same whether you are reading an English-language finance report in the United States, United Kingdom, Canada, Australia, Singapore or another international market; only local digit separators may display differently.

This conversion changes the size label attached to a number, while keeping its underlying value the same. On the short scale used by this tool, a million is 10⁶, a billion is 10⁹ and a trillion is 10¹². To change a value expressed in billion into trillion, divide by 1,000.
| Starting amount | Converted amount |
|---|---|
| 1 billion | 0.001 trillion |
| 2.5 billion | 0.0025 trillion |
| 10 billion | 0.01 trillion |
| 250 billion | 0.25 trillion |
Keep currency and unit conversion separate
For example, converting an amount labeled in dollars from billion to trillion changes the number's scale. It does not change dollars into another currency. The same arithmetic can describe revenue, a count or a measurement if the underlying unit stays consistent.
Check rounding and abbreviations
A small decimal result can still represent a large underlying amount. Keep the trillion label with the result, and retain enough decimal places before copying it into a report. Confirm whether an abbreviation such as M, B or T uses the same short-scale meaning as the source document. Multiplying the converted number by its target scale should reproduce the original full number.
