Gigabytes to Kilobytes formula
One gigabyte is 1,000,000 kilobytes, so kB = GB × 1,000,000. For the reverse, multiply kilobytes by 0.000001, or use the Kilobytes to Gigabytes converter.
Kilobytes, megabytes, gigabytes and terabytes here are decimal, as on drive labels: 1 kB = 1,000 bytes, 1 MB = 1,000 kB and 1 GB = 1,000 MB. Memory sizes and Windows count in binary units instead, where 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB and 1 GiB = 1,024 MiB, which is why a 1 TB drive shows as about 931 GiB. To switch between the two, use the gibibytes to gigabytes converter or the byte converter guide.
