| 2.5 billion | 2,500 million |
| 10 billion | 10,000 million |

Keep currency and unit conversion separate
For example, converting an amount labeled in dollars from billion to million 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 million 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.
