Formula and method

1,000 million = 1 billion = 1,000,000,000. This uses the short-scale billion of one thousand million. Older or regional long-scale usage can give the word billion a different meaning. Enter a known value in the units shown; editing a result solves the conversion in reverse.

1,000 million = 1 billion = 1,000,000,000

Assumptions and limitations
