# Bits to megabytes

**1 bit in megabytes: 1 bit = 1.25 × 10^-7 MB**

MB = bit × 1.25 × 10^-7

To convert bits to megabytes, multiply by 1.25 × 10^-7. 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 = bit × 1.25 × 10^-7. 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 bit?

One bit equals 1.25 × 10^-7 megabytes. MB = bit × 1.25 × 10^-7.

### How do you convert bits to megabytes?

Use MB = bit × 1.25 × 10^-7. So 10 bit is 0.00000125 MB.

### How many bits are in one megabyte?

One megabyte equals 8,000,000 bits, which is the reverse of the conversion above.

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

Decimal: 1,000,000 bytes.
