Large numbers appear in finance, population statistics, and internet metrics. "1.5k" means 1,500; "2.3M" means 2,300,000. Converting between named scales (thousand, million, billion) and decimal form prevents order-of-magnitude errors.

US and UK billions both mean 10⁹ in modern usage, though historical British "long scale" differed. Our converters use the short scale (1 billion = 1,000 million) standard in contemporary English.
