How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Edit a calculated value to solve backwards, or lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Formula and method

1,000 Mb/s = 1 Gb/s = 0.125 GB/s. This uses decimal network prefixes and eight bits per byte. A line rate does not guarantee a file-transfer rate because protocol overhead and congestion also matter. Enter a known value in the units shown; editing a result solves the conversion in reverse.

1,000 Mb/s = 1 Gb/s = 0.125 GB/s

Worked example

Enter these known values and leave the other values blank.

Megabits per second
1000 Mbps
Gigabits per second
1 Gbps
Gigabytes per second
0.125 GBps

Assumptions and limitations

  • This uses decimal network prefixes and eight bits per byte. A line rate does not guarantee a file-transfer rate because protocol overhead and congestion also matter.
  • The worked example uses the starting units. A unit selection preserves the quantity, so check the unit before entering a new number.

Common questions

Which data rate convention does this conversion use?

This uses decimal network prefixes and eight bits per byte. A line rate does not guarantee a file-transfer rate because protocol overhead and congestion also matter.

How should I use a rounded result?

Keep enough digits for the accuracy of the original measurement. Display rounding changes the visible precision, while the calculation retains additional digits.
