🔗 Yottabyte

🔗 Computing 🔗 Numbers 🔗 Measurement

The yottabyte is a multiple of the unit byte for digital information. The prefix yotta indicates multiplication by the eighth power of 1000 or 10²⁴ in the International System of Units (SI), and therefore one yottabyte is one septillion (one long scale quadrillion) bytes. The unit symbol for the yottabyte is YB. The yottabyte, adopted in 1991, is the largest of the formally defined multiples of the byte.

1 YB = 1000⁸bytes = 10²⁴bytes = 1000000000000000000000000bytes = 1000zettabytes = 1trillionterabytes

A related unit, the yobibyte (YiB), using a binary prefix, is equal to 1024⁸bytes (approximately 1.209 YB).
