Convert bandwidth and data-rate units

The Bandwidth Converter converts between every common data-rate unit — bits per second (bps, Kbps, Mbps, Gbps) and bytes per second (B/s, KB/s, MB/s, GB/s). Enter a value, pick your units, and get an instant, accurate result. It clears up the constant confusion between bits and bytes that trips up so many speed calculations.

Bits vs bytes: the core idea

Network speeds are measured in bits per second, while file sizes and download speeds are usually in bytes per second. One byte equals eight bits, so to convert Mbps to MB/s you divide by eight. That's why a "100 Mbps" connection downloads at about 12.5 MB/s. This converter does the factor-of-eight math for you in both directions.

How to use it

  1. Enter a value in the From field.
  2. Choose the unit you have and the unit you want.
  3. Read the converted bandwidth instantly.

Where this helps

  • Comparing internet plans quoted in different units.
  • Estimating download speeds in MB/s from an Mbps connection.
  • Network capacity planning across bits and bytes.
  • Understanding why your "fast" connection downloads files slower than expected.

A quick mental shortcut

To roughly convert Mbps to MB/s, divide by 8 (or, even simpler, divide by 10 for a conservative real-world estimate that also accounts for overhead). So a 200 Mbps line is about 25 MB/s in theory, and perhaps 20 MB/s in practice. The converter gives you the exact figure whenever you need precision.

Frequently asked questions

How do I convert Mbps to MB/s?

Divide by 8. One byte is 8 bits, so 100 Mbps equals 12.5 MB/s.

Why are internet speeds in bits, not bytes?

Network throughput has traditionally been measured in bits per second, while file sizes use bytes — hence the confusion.

What units does it support?

bps, Kbps, Mbps, Gbps and B/s, KB/s, MB/s, GB/s — converting freely between bits and bytes.

Is it free?

Yes, completely free with no sign-up, running entirely in your browser.
