1,000 kilobytes

= 0.001 GB= 1,000,000 B

equals 1,000 kilobytes

Formula: kB = MB × 1000

Megabyte to Kilobyte formula

kB = MB × 1000

Convert 5 megabytes to kilobytes

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

Unit definitions

What is a megabyte?

The megabyte (decimal) is one million bytes (1000²) under the SI convention. Photos, songs, and documents are commonly sized in megabytes. It differs from the mebibyte, which is 1,048,576 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
