Why is the multiplier 8,000 and not 1,024?

Networking speeds use SI (decimal) prefixes: 1 MB = 1,000,000 bytes and 1 kbps = 1,000 bits/s. So 1 MB/s = 8,000,000 bits/s = 8,000 kbps. If your context uses binary megabytes (MiB), multiply by 8,192 instead.

What is the difference between MB/s and Mbps?

MB/s (uppercase B) means megabytes per second. Mbps (lowercase b) means megabits per second. Since 1 byte = 8 bits, 1 MB/s = 8 Mbps. Storage devices typically use MB/s; network plans typically use Mbps.

My SSD reads at 3,500 MB/s — what is that in kbps?

3,500 MB/s × 8,000 = 28,000,000 kbps (28 Gbps). This illustrates why modern NVMe drives far outpace typical internet connections.

Does this converter use SI or binary units for megabytes?

SI (decimal) units: 1 MB = 1,000,000 bytes = 1,000 kB. This matches how network throughput and most OS file-transfer dialogs report speeds.

Summary

Enter a MB/s value and instantly see the equivalent in kbps (1 MB/s = 8,000 kbps).

How it works

Enter a throughput value in megabytes per second (MB/s) in the input field.
The tool multiplies by 8,000 to convert MB/s to kbps (since 1 byte = 8 bits and 1 MB = 1,000 kB).
The result in kilobits per second (kbps) appears immediately.
Use the reverse field to convert kbps back to MB/s.
Click "Copy" next to any result to copy the value to your clipboard.

Use cases

Translate storage drive throughput (e.g. 500 MB/s SSD) into kbps for bandwidth comparisons.
Express download speeds reported by browsers or OS in kbps for streaming bitrate planning.
Compare file transfer rates in MB/s against network plan speeds advertised in kbps or Mbps.
Estimate how many kbps a given MB/s transfer rate consumes on a shared connection.
Convert video encoding output MB/s to kbps to match codec bitrate settings.
