Megabits per second to Megabytes per second Converter Mbit/s → MB/s

1 megabit per second (Mbit/s) = 0.125 megabytes per second (MB/s). Type a value below — the conversion happens instantly, entirely on your device.

1 Mbit/s = 0.125 MB/s

100 megabits per second = 12.5 megabytes per second

100 × 0.125 = 12.5

1 Mbit/s equals 0.125 MB/s, so multiplying by 0.125 converts the value. The result describes the exact same quantity — only the measuring stick changes.

How to convert megabits per second to megabytes per second

megabytes per second = megabits per second × 0.125 — multiply the megabit per second value by 0.125.

Example: 100 Mbit/s = 12.5 MB/s.

To convert the other way: megabits per second = megabytes per second ÷ 0.125 — or use the dedicated MB/s to Mbit/s converter .

This is the conversion everyone actually wants: your internet plan is sold in megabits (Mbps) but your downloads show megabytes per second (MB/s), and 1 byte = 8 bits — so you divide by 8. A 100 Mbps plan tops out around 12.5 MB/s, and that's normal, not a fault. Overhead usually shaves a little more off.

About the units

What is a megabit per second?

A megabit per second is 1,000,000 bits/s — the unit internet plans are sold in ("100 Mbps"). Divide by 8 for megabytes per second.

What is a megabyte per second?

A megabyte per second is 8 megabits/s (1,000,000 bytes/s). It's what your browser or download shows — an 80 Mbps line tops out near 10 MB/s.

Frequently asked questions

How many megabytes per second are in 1 megabit per second?

1 megabit per second (Mbit/s) = 0.125 megabytes per second (MB/s).

What is the formula to convert megabits per second to megabytes per second?

megabytes per second = megabits per second × 0.125 — multiply the megabit per second value by 0.125.

How do I convert Mbit/s to MB/s without a calculator?

Multiply by 0.125 for a close estimate. Exact factor: 1 Mbit/s = 0.125 MB/s.

Is this Mbit/s-to-MB/s converter accurate and private?

Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.

Why is my download speed lower than my internet plan?

Because plans are measured in megabits (Mbps) and downloads in megabytes per second (MB/s). There are 8 bits in a byte, so 100 Mbps is only 12.5 MB/s even before real-world overhead. It's the units, not necessarily a slow connection.
