Usage notes

• Brazil (along with the US and UK) uses the short scale large-number naming system, while Portugal uses the long scale. The number 10¹⁸ (one quintillion) is expressed in Brazilian Portuguese as um quintilhão but in European and African Portuguese as [um]] trilhão.[1]
• In Portugal, um quintilhão means "one nonillion" (10³⁰) but is considered an informal spelling; quintilião is preferred in most circumstances.[2]
