# Free online data transfer rate converter

> Data transfer rate measures how fast data moves across a network or storage device. This converter handles both SI (1000-based) and IEC (1024-based) units used in networking and.

Convert between 10 data rate units including Mbps, Gbps, kbps, bytes per second, kibibits, mebibits, and more. Enter a value, choose units, and get the full conversion table instantly.

## Conversion factors (relative to bits per second)

| Unit | bps equivalent |
|------|---------------|
| bps | 1 |
| kbps | 1 000 |
| Mbps | 1 000 000 |
| Gbps | 1 000 000 000 |
| Tbps | 1 000 000 000 000 |
| Kibps | 1 024 |
| Mibps | 1 048 576 |
| Gibps | 1 073 741 824 |
| B/s (bytes/s) | 8 |
| kB/s (kilobytes/s) | 8 000 |

## Worked example

Your home internet connection is **500 Mbps**.

Converting to kbps: 500 × 1000 = **500 000 kbps**

Converting to MB/s: 500 ÷ 8 = **62.5 MB/s** (megabytes per second)

## Notes

- SI prefixes (kilo-, mega-, giga-) use powers of 1000 in networking standards (IEC 80000-13).
- IEC binary prefixes (kibi-, mebi-, gibi-) use powers of 1024, common in some storage contexts.
- 1 byte = 8 bits by definition; B/s and kB/s use this 8× multiplier.

## Frequently asked questions

### How does the data rate converter work?

Every unit is first converted to the base unit (bits per second) by multiplying by a fixed factor, then divided by the target unit's factor to get the result.

### What is the difference between Mbps and MBps?

Mbps means megabits per second (1 000 000 bits/s). MBps means megabytes per second, which is 8× larger. Internet speeds are typically advertised in Mbps while file transfer speeds often display in MBps.

### What is the difference between kilobits and kibibits?

Kilobits (kbps) uses the SI prefix: 1 kbps = 1000 bps. Kibibits (Kibps) uses the IEC binary prefix: 1 Kibps = 1024 bps. Networking hardware typically uses SI while some memory specs use IEC.

### How many kbps is 1 Mbps?

1 Mbps = 1000 kbps (using SI prefixes). Networks are rated in SI units.

### What units are supported?

Bits per second (bps), kilobits/s (kbps), megabits/s (Mbps), gigabits/s (Gbps), terabits/s (Tbps), kibibits/s (Kibps), mebibits/s (Mibps), gibibits/s (Gibps), bytes per second (B/s), and kilobytes per second (kB/s).
