# Bytes to megabytes

**1 byte in megabytes: 1 B = 0.000001 MB**

MB = B × 0.000001

To convert bytes to megabytes, multiply by 0.000001. 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 MB = B × 0.000001. Both units measure data, so the conversion is a fixed factor that never changes.

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

## Common questions

### How many megabytes are in one byte?

One byte equals 0.000001 megabytes. MB = B × 0.000001.

### How do you convert bytes to megabytes?

Use MB = B × 0.000001. So 10 B is 0.00001 MB.

### How many bytes are in one megabyte?

One megabyte equals 1,000,000 bytes, which is the reverse of the conversion above.

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

Decimal: 1,000,000 bytes.
