## How the conversion works

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

> Kilobyte: Decimal: 1,000 bytes.

## Common questions

### How many kilobytes are in one megabit?

One megabit equals 125 kilobytes. kB = Mb × 125.

### How do you convert megabits to kilobytes?

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

### How many megabits are in one kilobyte?

One kilobyte equals 0.008 megabits, which is the reverse of the conversion above.

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

Decimal: 1,000 bytes.
