How to convert Mbps to MB/s
- 1 Type a value in the megabits per second box; the megabytes per second appear as you type.
- 2 Or type in the megabytes per second box to convert the other way.
- 3 Use the conversion table for common values.
Estimating download time
Divide the plan speed in Mbps by 8 for MB/s, then divide the file size in MB by that speed for seconds. A 4 GB file is 4,000 MB; at 100 Mbps (12.5 MB/s) it takes about 5 minutes 20 seconds. Convert file sizes with GB to MB and times with the Time Converter.
- Run a speed test near the router and again in the room you use most.
- Use a cable for large downloads; it is usually faster than Wi-Fi.
- Real speeds are often 70% to 90% of the advertised figure.
Features
Divide by 8
The exact relationship between bits and bytes.
Two-way
Type MB/s to get Mbps.
Plan speeds
Common plans from 1 Mbps to 10 Gbps in the chart.
When to use it
Choosing a plan
A 50 Mbps plan gives up to 6.25 MB/s. Converting file sizes too? Use GB to MB.
Download time
Divide the file size in MB by the speed in MB/s. A 2 GB file at 6.25 MB/s takes about 5 minutes 20 seconds.
Checking your speed
Speed tests report Mbps, while Steam and browsers show MB/s; convert before comparing.
Uploads and video calls
An HD video call needs about 1.5 to 3 Mbps up and down.

Frequently asked questions
How do I convert Mbps to MB/s?
Divide by 8. 200 Mbps is 25 MB/s.
Why is my download slower than my plan?
Plans are in megabits, downloads in megabytes, so divide by 8. Wi-Fi, network traffic and server speed reduce it further.
How fast is 1 Gbps in MB/s?
1,000 Mbps is 125 MB/s.
What is the difference between Mb and MB?
Mb is megabits, MB is megabytes. A byte is 8 bits.
How long does it take to download 1 GB at 100 Mbps?
At 12.5 MB/s, about 80 seconds, in ideal conditions.
Is MBps the same as MB/s?
Yes. Both mean megabytes per second.
What speed do I need for 4K streaming?
Streaming services recommend about 15 to 25 Mbps for 4K video.
Does Wi-Fi reduce speed?
Often. Distance, walls and older routers can cut real speeds well below the plan.
Why do providers use Mbps?
Network equipment has always been measured in bits per second, and the larger number looks better in adverts.
What is a good internet speed for a home?
For one or two people browsing and streaming, twenty-five to fifty megabits per second is usually enough. Larger families who stream, game and work from home often prefer one hundred or more.
Why is upload speed lower than download?
Many home connections are built for downloading, so they give less capacity for uploading. Fibre plans often offer equal speeds both ways.
Why does a speed test show a different result each time?
Network traffic, Wi-Fi interference and the server chosen for the test all change from moment to moment. Run the test a few times at different hours to see your typical speed.
Does the number of devices affect speed?
Yes. Every phone, laptop and television using the connection shares the available speed, so several streams at once can make each one slower.
