Mbps to MB/s Converter

Convert Megabits per second (Mbps) to Megabytes per second (MB/s). Learn why your download speed in your browser is one-eighth of your ISP plan.

Direct Formula: To convert Mbps to MB/s, use MB/s = Mbps ÷ 8. For example, 100 Mbps equals 12.50 MB/s.

Value in Mbps

12.5 MB/s

Multiply Mbps by 0.125 to get MB/s. This converts units; it does not test your connection.

Formula

How to Convert Mbps to MB/s

MB/s = Mbps ÷ 8

1 Byte consists of 8 bits. Divide any Megabit value by 8 to get the equivalent Megabyte rate.

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.

AEO / Expert Answers

How many MB/s is 100 Mbps?

100 Mbps is exactly 12.5 MB/s under ideal conditions (100 ÷ 8 = 12.5). In practice, with network overhead, expect roughly 11.2 to 11.8 MB/s.

How do I convert Mbps to MB/s in my head?

Divide the number by 8. Alternatively, halve it three times: 100 -> 50 -> 25 -> 12.5 MB/s.

What is 500 Mbps in MB/s?

500 Mbps equals 62.5 MB/s theoretical transfer rate.
