68719476736

68719476736 is the decimal representation of the number 2^36. In binary it is a 1 followed by 36 zeros, and in hexadecimal it is 0x1000000000. This value corresponds to 64 gibibytes (64 GiB) of data, since 1 GiB equals 2^30 bytes.

In computing, 2^36 is a common boundary used to describe memory and storage capacities and address spaces. For example, a 36-bit addressing scheme can address up to 2^36 bytes, which equals 64 GiB, assuming byte-addressable memory. Although modern systems typically employ larger address spaces, 2^36 remains a notable milestone as an exact power-of-two boundary.

The number may appear in discussions of digital storage, memory capacity, or file sizes, particularly when distinguishing between binary-based units (gibibytes) and decimal-based units (gigabytes).
