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

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

What is the difference between kbps and kBps?

kbps (lowercase b) means kilobits per second. kBps (uppercase B) means kilobytes per second. Since 1 byte = 8 bits, 1 kBps = 8 kbps. This converter uses the common lowercase-b kilobits convention.

My ISP advertises 100 Mbps — what is that in MB/s?

100 Mbps = 100,000 kbps. Divide by 8,000 to get 12.5 MB/s. So a 100 Mbps connection can theoretically download about 12.5 megabytes every second.

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 file sizes are typically reported by operating systems and is the standard for network throughput.

Megabytes per second (MB/s) — reverse

Result in kbps appears on the right.

Result

kbps → MB/s

— MB/s

MB/s → kbps

— kbps

Formula: MB/s = kbps ÷ 8,000 | Uses SI decimal units (1 MB = 1,000,000 bytes).

Summary

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

How it works

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

Use cases

Translate ISP speed plan rates (e.g. 100,000 kbps) into MB/s for practical download estimates.
Calculate how fast a file will download given a connection speed in kbps.
Compare network interface specs stated in kbps with storage throughput in MB/s.
Convert video streaming bitrates from kbps to MB/s to estimate bandwidth consumption.
Evaluate VoIP and conferencing bandwidth requirements expressed in kbps.
