GB to KB
Converts gigabytes to kilobytes using both 1000 and 1024 and shows both answers exactly.
You convert gigabytes to kilobytes through a million: multiply by 1,000,000 or by 1,048,576. One gigabyte holds 1,048,576 KB under the binary rule.
Kilobytes matter where a program accepts sizes only in them, for example in cache settings or server quotas.
Formula
Decimal (1000): KB = GB × 1,000,000. Binary (1024): KB = GB × 1,048,576.
