A googolbell is equal to 105000 or 1 followed by 5,000 zeros. The name was coined by Sbiis Saibian.[1] It is the 50th power of a googol and the fifth power of a googolchime. It is the square root of a googoltoll. It is also called one hundred milliquinsexagintasescentillion in the short scale. It is 5,001 digits long.

Googolbell is also known as "one hundred milliasescenquinsexagintillion" according to Landon Curt Noll's The English name of a number.

Its full decimal expansion is shown below:
