100000000000

100000000000 is the natural number that follows 99999999999 and precedes 100000000001. In scientific notation, it equals 1 × 10^11, and in decimal form it is 100,000,000,000. It is a 12-digit number composed of a 1 followed by eleven zeros. Its prime factorization is 2^11 × 5^11, so it is divisible by 2 and 5 and by powers of ten.

In English usage, this quantity is read as one hundred billion in the short scale. In countries using the long scale, it is often described as one hundred milliards or as one hundred thousand million, reflecting naming differences for large numbers.

The magnitude places the number in the hundreds of billions, between 10^10 and 10^12, and it is a common benchmark for data sizes and large-scale counts. For example, 100,000,000,000 bytes equals about 100 decimal gigabytes; in binary terms that storage amounts to about 93.1 gibibytes.

In natural phenomena and estimation contexts, figures near this scale appear in astronomy and cosmology discussions—e.g., rough estimates of the Milky Way's star count have been stated on the order of 100 billion, though precise figures vary by method and model.

As a mathematical object, 10^11 is a composite, even integer that factors as 2^11 × 5^11, illustrating its relation to powers of ten.
