# Megabits to bytes

**1 megabit in bytes: 1 Mb = 125,000 B**

B = Mb × 125,000

To convert megabits to bytes, multiply by 125,000. The table below gives the values people look up most often, and the converter works for any number.

| 40 Mb | 5,000,000 |
| 50 Mb | 6,250,000 |
| 75 Mb | 9,375,000 |
| 100 Mb | 12,500,000 |
| 250 Mb | 31,250,000 |
| 500 Mb | 62,500,000 |
| 1,000 Mb | 125,000,000 |

## How the conversion works

The relationship is B = Mb × 125,000. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bytes are in one megabit?

One megabit equals 125,000 bytes. B = Mb × 125,000.

### How do you convert megabits to bytes?

Use B = Mb × 125,000. So 10 Mb is 1,250,000 B.

### How many megabits are in one byte?

One byte equals 0.000008 megabits, which is the reverse of the conversion above.
