1 gigabyte = 10⁹ bytes (as defined by hard drive manufacturers) or 2³⁰ ≈ 1.074×10⁹ bytes (as used by operating systems). Widely used to indicate storage capacity of smartphones, USB drives, and hard disks. Used globally in daily life, though confusion exists between decimal and binary interpretations (IEC recommends using GiB for binary).
