Etymology edit
Borrowed from French quintillion.
Pronunciation edit
- Hyphenation: quin‧ti‧lhão
Noun edit
quintilhão m (plural quintilhões)
- (Brazil, cardinal number) quintillion (1018)
- Synonym: (Angola, Portugal) trilião

Usage notes edit
- Portuguese-speaking countries follow the traditional long scale, with the exception of Brazil which adopted the short scale used in the UK and US. The number 1018 is expressed as mil triliões in African and European Portuguese, but as um trilhão in Brazilian Portuguese.[1]
- The Angolan Government proscribes the use of long scale.[2]
- In Portugal, the alternative um quintilhão (“1030”) is an informal spelling of the preferred and proscribed um trilião.[3]
