Data Transfer Rate Converter

Convert between Mbps, Gbps, MB/s and other bandwidth units.

Your internet plan says 100 Mbps, but downloads top out around 12.5 MB/s — and both numbers are correct. Network speeds are quoted in megabits per second while file sizes and download managers use megabytes, and with 8 bits to a byte the same connection looks 8× slower when the unit changes.

This converter translates between bits-per-second units (bps, Kbps, Mbps, Gbps) and bytes-per-second units (KB/s, MB/s, GB/s) instantly. Use it to sanity-check an ISP's advertised speed against real download rates, estimate how long a transfer will take, or spec network hardware without unit slip-ups.

How to use Data Transfer Rate Converter

  1. 1

    Enter the speed value

    Type the transfer rate you want to convert.

  2. 2

    Choose the source unit

    Bits-based (Mbps, Gbps) or bytes-based (MB/s, GB/s).

  3. 3

    Read the converted rate

    The result updates instantly as you type.

Frequently asked questions

Common mistakes to avoid

  • Reading Mbps (megabits) as MB/s (megabytes) — an 8× overestimate of download speed.
  • Forgetting protocol overhead: real-world throughput is typically 5–10% below the raw link rate.
