How the Bandwidth Calculator Works

Bandwidth = Data Volume / Target Duration

Bandwidth defines maximum theoretical data throughput per unit of time across a physical or wireless transmission channel.

Mbps (Megabit per second)Used by ISPs and Speedtests. Lowercase 'b'. 1 Mbps = 1,000,000 bits/s.
vs
MB/s (Megabyte per second)Used by Steam, Chrome, Windows. Uppercase 'B'. 1 MB/s = 8,000,000 bits/s.

Frequently Asked Questions About Bandwidth Calculator

What is the difference between bandwidth and internet speed?

Bandwidth is the maximum capacity or volume of data that can pass through a pipe per second, while speed represents how rapidly packets travel from source to destination.
