Instantly convert between Gigabytes (GB) and Kilobytes (KB) with our bidirectional tool. Free, fast, and accurate - no installation required!
Our bidirectional converter instantly calculates between GB and KB using precise conversion factors:
A Gigabyte (GB) is a unit of digital information storage equal to 1,073,741,824 bytes (2^30 bytes). A Kilobyte (KB) is equal to 1,024 bytes (2^10 bytes). This means 1 GB is equivalent to 1,048,576 KB.
There are two standards for data measurement:
- Binary (base 2): 1 GB = 1,048,576 KB (used by most operating systems)
- Decimal (base 10): 1 GB = 1,000,000 KB (used by storage manufacturers)
Our converter uses the binary standard which is more common in computing contexts.
