Mbps to KB/s Converter
1 Mbps = 125 KB/s. Enter a value. The result updates immediately.
Convert
Accuracy and rounding
Use bits per second for network rates and bytes per second for file transfer; the factor of eight matters.
Transfer-rate pages keep bits and bytes separate. One byte is eight bits, so Mbps and MB/s are not interchangeable.
For file-transfer estimates, round after converting between bits and bytes, then account for network overhead separately.
How to convert Mbps to KB/s
- Enter the value in Mbps.
- Select Mbps as the source unit.
- Select KB/s as the target unit.
- Read or copy the result.

| Mbps | KB/s |
|---|---|
| 1 Mbps | 125 KB/s |
| 5 Mbps | 625 KB/s |
| 10 Mbps | 1,250 KB/s |
| 50 Mbps | 6,250 KB/s |
| 100 Mbps | 12,500 KB/s |
Formula
KB/s = Mbps x 125
Example: 1 Mbps = 125 KB/s.

Fixed digital relationships: 1 byte = 8 bits, with decimal SI prefixes for transfer rates.
Common questions
How do I convert Mbps to KB/s?
Enter the Mbps value in the converter, or multiply by the factor shown in the formula. 1 Mbps = 125 KB/s.
What should I watch out for?
Network speeds are usually bits per second, while file transfers are often shown in bytes per second.
Where does this data rate conversion come from?
Fixed digital relationships: 1 byte = 8 bits, with decimal SI prefixes for transfer rates. ConverterBase uses stable definitions and fixed conversion factors, not live or rounded market data.
