Kilobytes to Gigabytes formula
Converting kilobytes to gigabytes is a single multiplication by 1e-06.
GB = KB × 1e-06
Why this factor: the kilobyte and the gigabyte are both defined against the byte, so dividing one definition by the other gives 1e-06 directly. Both definitions are set out in full below.
To go the other way, divide by 1e-06 — or use the Gigabytes to Kilobytes converter, which is the same calculation reversed.
Worked example
Start with 500 KB. Multiply by 1e-06 to get 0.0005 GB.
500 KB × 1e-06 = 0.0005 GB
The converter above does this for any value you type, in either direction.
What is a kilobyte?
A kilobyte is 1,000 bytes in the decimal convention used by storage manufacturers and standards bodies.
Definition: Exactly 1,000 bytes under SI prefixes. The binary equivalent, 1,024 bytes, is properly the kibibyte (KiB).
Where it is used: Small file sizes, text documents, and web page weights.
Worth knowing: This decimal-versus-binary split is why a '1 TB' drive shows as about 931 GB in Windows: the drive uses 10¹², the OS displays 2⁴⁰.
What is a gigabyte?
A gigabyte is one billion bytes — the everyday unit of storage and memory capacity.
Definition: Exactly 1,000,000,000 bytes under SI prefixes. The binary gibibyte (GiB) is 1,073,741,824 bytes.
Where it is used: Phone and laptop storage, RAM capacity, video file sizes, and cloud storage plans.
Kilobytes vs Gigabytes
The kilobyte and the gigabyte belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
