Usage notes
- 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 1015 is expressed as mil biliões in African and European Portuguese, but as um quadrilhão/quatrilhão in Brazilian Portuguese.[1]
- The Angolan Government proscribes the use of long scale.[2]
- In Portugal, the alternative um quadrilhão/quatrilhão (“one septillion, 1024”) is an informal spelling of the preferred and proscribed um quadrilião/quatrilião.[3]
