Bandwidth Converter

Convert a data rate between bits, kilobits, megabits and gigabits per second.

Calculations run in your browser. The tool does not send your inputs to a server.

01Your inputs

Your result will appear here. Choose an action after checking your inputs.

A quick guide

How to use this tool

  1. Check the example and the unit beside each input.
  2. Enter your values and choose Calculate.
  3. Review the result and assumptions, then copy what you need.

Reset example restores the starting values. Clear removes text and number inputs, returns choices to their first valid option, and removes the result.

Reference guide

Explanation and worked examples

These are decimal bit rates. Eight bits make one byte; 1,000 Mbps is 1 Gbps, not 1,000 megabytes per second.

Use in day-to-day IT work

Prepare addressing or transfer estimates for a network change, migration or support ticket.

Checks before applying the result

  • Compare the result with IPAM, VLAN boundaries, routes and DHCP reservations before allocating addresses.
  • Use measured sustained throughput for time estimates; link speed alone excludes contention and protocol overhead.
New to the terminology?
CIDR
An address block written with a slash and prefix length, such as /24.
Prefix
The number of address bits fixed to identify a network.
Mbps
Millions of bits per second. Divide by eight to compare with MB/s.
