FAQ
How many KB are in a GB?
1,048,576 KB. A gigabyte holds 1,024 megabytes and each megabyte holds 1,024 kilobytes, so 1 GB = 1,048,576 KB, or 2²⁰ KB. That is the binary gigabyte of Windows, RAM and this converter; the IEC calls it the gibibyte (GiB).
What is the formula to convert gigabytes to kilobytes?
Multiply the number of gigabytes by 1,048,576: KB = GB × 1,048,576. For example, 0.5 GB = 524,288 KB, 2 GB = 2,097,152 KB and 16 GB = 16,777,216 KB. Dividing by 1,048,576 takes kilobytes back to gigabytes.
Is a gigabyte 1,000,000 or 1,048,576 kilobytes?
Both are in use. Windows, RAM and this converter count in binary units: 1 GB = 1,048,576 KB. Drive packaging and mobile plans count in decimal (SI) units: 1 GB = 1,000,000 KB. That is why a file Windows calls 1 GB is 1,073,741,824 bytes, while the gigabyte on the box is 1,000,000,000 bytes.
