• gigabytes: A gigabyte is usually 1,073,741,824 bytes. Phones ship with 128–512 GB; a 4K movie is ~10–25 GB.
• kilobytes: A kilobyte is often 1,024 bytes (binary), but drive makers use 1,000 — the classic "missing space" mystery.
• Storage uses binary: 1 KB = 1,024 B. Drive makers often quote decimal (1 KB = 1,000 B), so real capacity looks smaller.
1 GB = 1,048,576 KB. Use the converter above to compute any value, or multiply GB by 1,048,576.
