A quinquagintacentillion is equal to \(10^{453}\) in the short scale and \(10^{900}\) in the long scale by the Conway and Guy's naming system[1][2][3][4] as it is the 150th -illion number.
In the long scale, \(10^{453}\) is called quinseptuagintilliard.
It is referred to as quinquaginticentillion in Cookiefonster's extension of Jonathan Bowers system of -illions[5].
