MB/s to Mbps converter
To convert MB/s to Mbps, multiply by 8. A game launcher showing 25 MB/s is pulling 200 Mbps, and 12.5 MB/s is a full 100 Mbps connection.
Tip: paste a reading like “12.4 MB/s” and the unit is picked for you.
1 MB/s equals:
- bps8,000,000
- kbps8,000
- Mbps8
- Gbps0.008
- B/s1,000,000
- kB/s1,000
- MB/s1
- GB/s0.001
- MiB/s0.953674
Runs entirely in your browser. Nothing you type is sent anywhere.
Formula
1 MB/s = 8,000,000 bits and 1 Mbps = 1,000,000 bits, so:
Common conversions
| MB/s | Mbps |
|---|---|
| 0.5 MB/s | 4 Mbps |
| 1 MB/s | 8 Mbps |
| 5 MB/s | 40 Mbps |
| 10 MB/s | 80 Mbps |
| 12.5 MB/s | 100 Mbps |
| 25 MB/s | 200 Mbps |
| 50 MB/s | 400 Mbps |
| 100 MB/s | 800 Mbps |
| 125 MB/s | 1,000 Mbps |
Examples: is my download using my full plan?
Game launchers, browsers, app stores and cloud-drive clients report download speed in megabytes per second, while your provider sells megabits per second. Multiplying by 8 puts both on the same scale.
- Steam on a 500 Mbps plan. The download page shows 60 MB/s. 60 × 8 = 480 Mbps, or 96% of the plan. That is as good as it gets.
- A browser download on 100 Mbps. The file comes in at 11.2 MB/s. 11.2 × 8 = 89.6 Mbps, about 90% of the plan, which is normal once overhead is counted.
- A console update on gigabit. The reading is 45 MB/s, which is 360 Mbps. That is well below a 1,000 Mbps plan. Try a wired connection, a different time of day, or compare a speed test with the speed test checker; the download server itself may be the cap.
Pitfall: MiB/s shown as MB/s
Some operating systems and download tools measure in mebibytes (1,048,576 bytes) but label the result "MB/s". One MiB/s is 8.388608 Mbps, so a reading of 50 MiB/s is really 419.43 Mbps rather than 400. If your figure looks about 5% worse than expected, this is often why. Choose MiB/s in the converter above when you know the app counts in 1,024s.
Also expect a real download to land a little below the plan: about 85–95% is typical on a good wired connection. On Wi-Fi, lower figures are common and are not always a fault of the line.
When to use which unit
Use Mbps to compare with plans and speed tests; use MB/s to predict how long files take. To go from a plan speed to what the download bar should show, use Mbps to MB/s. For storage and 10 GbE speeds in the gigabyte range, GB/s to Mbps keeps the numbers readable. The full story is in Mbps vs MB/s.
Frequently asked questions
Is 1 MB/s faster than 1 Mbps?
Yes, eight times faster. 1 MB/s is one million bytes per second and each byte is 8 bits, so it equals 8 Mbps.
Why is my download in MB/s so much lower than my plan in Mbps?
Usually it is not. Divide the plan by 8 first: a 200 Mbps plan peaks at 25 MB/s. If the download shows 22 MB/s, that is 176 Mbps, or 88% of the plan.
What MB/s should a 1 Gbps plan show?
The maximum is 125 MB/s. With typical overhead on wired gigabit, a speed test around 940 Mbps corresponds to about 117.5 MB/s, and real downloads often land between 100 and 117 MB/s if the server can keep up.
Can I make Steam show Mbps instead of MB/s?
Yes. Steam's download settings include an option to display download rates in bits per second, which you can then compare directly with your plan.
