Femtillion

Femtillion is equal to \(10^{3\text{ quadrillion }3}\).Illion Numbers by Jonathan Bowers The term was coined by Jonathan Bowers. The value of quadrillion is intended to be given in the short scale, and hence the femtillion us intended to coincide with \(10^{3\times10^{15}+3}\), i.e. a 1 followed by 3,000,000,000,000,003 zeros. If we interpret quadrillion in the long scale instead, then the femtillion coincides with \(10^{3\times10^{24}+3}\), i.e. a 1 followed by 3,000,000,000,000,000,000,000,003 zeros. As a conclusion, it is 3,000,000,000,000,004 digits long in the short scale, or 3,000,000,000,000,000,000,000,004 digits long in the long scale.
Written out as a power of 10, femtillion (in the short scale) is:
In long scale:
Femtillion is also known as one milliamilliamilliamilliamilliatillion according to Landon Curt Noll's The English name of a number.
== Etymology ==
The name of this number is based on the suffix "-illion" and the SI prefix "femto-".
