Megabits per Second to Megabytes per Second (Mbps to MB/s)
1 megabit per second = 0.125 megabytes per second (MB/s). Turn your internet plan's Mbps into the MB/s your downloads show, with both charts.
Megabyte per Second (MB/s) = Megabit per Second (Mbps) × 0.125
Megabit per Second (Mbps): A megabit per second is 1,000,000 bits per second. Broadband and Wi-Fi speeds are advertised in Mbps; divide by 8 to get megabytes per second.
Megabyte per Second (MB/s): A megabyte per second is 1,000,000 bytes or 8 megabits per second. A 100 Mbps connection downloads at most 12.5 MB/s.
| Megabit per Second (Mbps) | Megabyte per Second (MB/s) |
|---|---|
| 1 | 0.125 |
| 5 | 0.625 |
| 10 | 1.25 |
| 25 | 3.125 |
| 50 | 6.25 |
| 100 | 12.5 |
Internet providers, Wi-Fi routers and speed tests measure in megabits per second, but browsers, game launchers and file managers show download progress in megabytes per second. A byte is 8 bits, so a 100 Mbps plan can deliver at most 12.5 megabytes per second, and that factor of eight is why the two numbers never seem to match.
Real downloads land a little below that ceiling, because part of each packet is taken up by headers and the line is shared with everything else on the network. A gigabit connection that tests at about 940 Mbps over wired Ethernet is working normally, since that is the usual usable rate once protocol overhead is subtracted.
How to use this tool
- Type a value in the Megabit per Second box to see it in megabytes per second, or type in the Megabyte per Second box to convert the other way.
- Press ⇄ to swap the two units, or Load example for a typical value.
- Check the charts below for common values; for other units, open the Data Transfer Rate converter.
Formula
Megabyte per Second (MB/s) = Megabit per Second (Mbps) × 0.125
Megabit per Second (Mbps) = Megabyte per Second (MB/s) × 8
Both factors come from exact definitions: 1 megabyte per second = 8 megabits per second and 1 megabit per second = 0.125 megabytes per second (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
100 Mbps × 0.125 = 12.5 MB/s
50 MB/s × 8 = 400 Mbps

| FCC broadband benchmark before 2024, download | 25 | 3.125 |
| FCC broadband benchmark since 2024, download | 100 | 12.5 |

Quick mental estimate
Divide by 8 by halving three times: 100 → 50 → 25 → 12.5, so a 100 Mbps plan tops out at 12.5 megabytes per second. Expect real transfers to run roughly 5 to 10% below that figure.
Use the converter or the charts when the exact figure matters.
The two units
Megabit per Second (Mbps): A megabit per second is 1,000,000 bits per second. Broadband and Wi-Fi speeds are advertised in Mbps; divide by 8 to get megabytes per second.
Megabyte per Second (MB/s): A megabyte per second is 1,000,000 bytes or 8 megabits per second. A 100 Mbps connection downloads at most 12.5 MB/s.
Frequently asked questions
How many MB/s is 100 Mbps?
100 megabits per second is 12.5 megabytes per second at most. In practice a download on that plan usually shows somewhere around 11 to 12 MB/s.
Why does my gigabit plan download at only about 110 MB/s?
A gigabit per second is 125 megabytes per second before overhead, and about 117 MB/s is the practical ceiling on wired Gigabit Ethernet. A result near 110 MB/s is normal; over Wi-Fi it is often lower.
Is Mbps the same as MBps?
No. Mbps (lowercase b) means megabits per second, while MBps or MB/s (uppercase B) means megabytes per second, eight times larger. The capital letter is the only clue, so read speed figures carefully.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
