Un billiard vaut 10 : 1 000 000 000 000 000, soit 1 000 billions. Par exemple, « 1 288 269 950 042 115 » représente 1 billiard 288 billions 269 milliards 950 millions 42 mille 115. Pour exprimer un nombre de cet ordre de grandeur, la notation scientifique est préférée. Par exemple, 124 billiards est équivalent à en notation scientifique ou 124×10 en notation ingénieur.

En biljard (äldre stavning billiard) betecknar det mycket stora talet 1 000 000 000 000 000 eller 10¹⁵ i tiopotensnotation och 1000⁵ i tusenpotensnotation. Ordet är bildat från latinets bis, två gånger, och milliard. Samma antal kan anges som tusen biljoner eller en miljon miljarder. En biljard kan också anges med prefixet peta (P) och en biljarddel med prefixet femto (f). Ordets användning i svenska språket är omtvistad.
