How to convert gigabytes to kilobytes
Lowercase b means bit; uppercase B means byte (8 bits). Decimal kB, MB and GB use powers of 1000; binary KiB, MiB and GiB use powers of 1024. Choose the label that matches the source measurement.
kB = GB × 1000000One gigabyte is 1000000 kilobytes, so a single multiplication converts any value.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
