Formula

How the Mbps to GB Converter Works

Data in GB = (Speed in Mbps ÷ 8) × Seconds Elapsed ÷ 1,000

Divide your Mbps speed by 8 to determine MB/s, multiply by duration in seconds, and divide by 1,000 (or 1,024 for binary GiB) to get total Gigabytes.

Mbps (Megabit per second)Used by ISPs and Speedtests. Lowercase 'b'. 1 Mbps = 1,000,000 bits/s.

MB/s (Megabyte per second)Used by Steam, Chrome, Windows. Uppercase 'B'. 1 MB/s = 8,000,000 bits/s.
