Result

1,000,000 kilobytes

= 1,000,000,000 B= 1,000 MB

equals 1,000,000 kilobytes

Formula: kB = GB × 1000000

Gigabyte to Kilobyte formula

kB = GB × 1000000

Convert 5 gigabytes to kilobytes

  1. Start with 5 gigabytes.
  2. Multiply by the conversion factor: 5 × 1,000,000 = 5,000,000.
  3. So 5 GB = 5,000,000 kB.

Unit definitions

What is a gigabyte?

The gigabyte (decimal) is one billion bytes (1000³) under the SI convention that drive and phone makers use. Movies, apps, and storage capacities are usually quoted in gigabytes. It is smaller than a gibibyte (1,073,741,824 bytes).

What is a kilobyte?

The kilobyte (decimal) is exactly 1000 bytes under the SI convention used by storage manufacturers and networking. It should not be confused with the kibibyte (1024 bytes). Small text files and icons are measured in kilobytes.

Frequently asked questions

How many kilobytes are in one gigabyte?

One gigabyte equals 1,000,000 kilobytes (1 GB = 1,000,000 kB).

How do I convert gigabytes to kilobytes?

Multiply the value in gigabytes by 1,000,000. For example, 10 GB × 1,000,000 = 10,000,000 kB.

Which is bigger — a gigabyte or a kilobyte?

A gigabyte is bigger: one gigabyte contains 1,000,000 kilobytes.

Is this gigabyte to kilobyte converter free?

Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
