Result

1,000,000 bytes

= 0.001 GB= 0.000001 TB

equals 1,000,000 bytes

Formula: B = MB × 1000000

Megabyte to Byte formula

B = MB × 1000000

Convert 5 megabytes to bytes

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

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 byte?

The byte is eight bits, the basic addressable unit of computer memory and storage. One byte can represent a single text character in older encodings. It is the reference unit from which kilobytes, megabytes, and their binary counterparts are built.

Frequently asked questions

How many bytes are in one megabyte?

One megabyte equals 1,000,000 bytes (1 MB = 1,000,000 B).

How do I convert megabytes to bytes?

Multiply the value in megabytes by 1,000,000. For example, 10 MB × 1,000,000 = 10,000,000 B.

Which is bigger — a megabyte or a byte?

A megabyte is bigger: one megabyte contains 1,000,000 bytes.

Is this megabyte to byte converter free?

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