Bandwidth Calculations

This page will help you understand how bandwidth is broken down between bits, bytes, and the other different speeds.

Here is a good calculator: http://www.matisse.net/bitcalc/

A chart of what various speeds are:

• 1 gigabyte = 8,589,934,592 bits
• 1 gigabit = 1,073,741,824 bits
• 1 megabits = 128 kilobytes
• 1 megabits = 1024 kilobytes

• T3 = 44,736,000 bits per second.
• T1 = 1,544,000 bits per second.
• 100 ethernet = 100,000,000 bits per second.

Data movement

A 100mb ethernet can move a gigabyte in:

85 seconds = 1.43 minutes

A T1 can move a Gigabyte in:

5563 seconds = 92.71 minutes
