Key Formulas

Megabyte → Gigabyte

GB = MB × 0.000976563

Gigabyte → Megabyte

MB = GB × 1024

Gigabyte → Terabyte

TB = GB × 0.000976563

Terabyte → Gigabyte

GB = TB × 1024

Formula

PB = TB ÷ 1024

A terabyte is 1/1024 of a petabyte — since 1 PB = 1024 TB. Enterprise and hyperscale storage often operates at PB scale while individual systems might be provisioned in TB. Understanding the 1024:1 relationship is essential for capacity planning across multi-petabyte data lakes.
