# Megabytes to bytes

**1 megabyte in bytes: 1 MB = 1,000,000 B**

B = MB × 1,000,000

To convert megabytes to bytes, multiply by 1,000,000. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is B = MB × 1,000,000. Both units measure data, so the conversion is a fixed factor that never changes.

> Megabyte: Decimal: 1,000,000 bytes.

## Common questions

### How many bytes are in one megabyte?

One megabyte equals 1,000,000 bytes. B = MB × 1,000,000.

### How do you convert megabytes to bytes?

Use B = MB × 1,000,000. So 10 MB is 10,000,000 B.

### How many megabytes are in one byte?

One byte equals 0.000001 megabytes, which is the reverse of the conversion above.

### Is there more than one kind of megabyte?

Decimal: 1,000,000 bytes.
