Convert Megabit per second to Megabyte per second (decimal)

Convert megabits per second to megabytes per second for Internet plans, download bars, and disk-write speeds that mix bits with bytes.

Convert Mbps to MB/s

Enter a rate in megabit per second [Mbps] to see megabyte per second (decimal) [MB/s], or vice versa.

12.5

Formula: 1 Mbps = 0.125 MB/s

What this conversion means in practice

ISPs advertise Mbps; file managers think MB/s. Dividing by eight is only half the story, you also need consistent SI definitions for mega, which this page aligns with the main data-rate tool.

Express both units in bits per second, then divide: the multiplier from Mbps to MB/s is 0.125.

Megabit per second to Megabyte per second (decimal) FAQ

Mbps to MB/s for bandwidth tests and Steam-style throughput.

How many MB/s are in one Mbps?

Multiply Mbps by 0.125 to obtain MB/s. Factors align megabit-per-second SI prefixes with decimal megabyte-per-second (8 × 10⁶ bits per second).

Why involve bits per second internally?

Megabits per second counts bits; megabytes per second counts bytes (8 bits). Expressing both in bits per second removes ambiguity before dividing.

Does this include IEC binary prefixes?

This focused pair uses Mbps and decimal MB/s as implemented in the main Data Transfer Rate Converter’s SI column (not MiB/s). Toggle IEC there when you need KiB/s or MiB/s.
