Here's a quick Mbps-MB/s converter. Enter either field and it instantly converts the other field.

Mbps or MBPS? Which is correct for network speed?

I hope you haven't forgotten the basics:

  • Internet speed is measured in bits
  • Bits are represented with lower case b
  • File size is measured in bytes
  • Bytes are represented with capital B
  • Megabyte =MB and Megabit=Mb
  • 1 MB (Megabyte) = 8 Mb (Megabit)
  • MBps or MB/s = Mega Bytes per second
  • Mbps = Mega bits per second

People often forget that the internet speed is measured in bits, but they know that the file size is measured in bytes. And that often creates a confusion.

When you have an internet speed of 40 Mbps, you may wrongly assume that you can download 40 MB per second.

A byte is equal to 8 bits so the internet speed you see as 40 Mbps can only download a maximum of 5 MB of data per second.

Of course that is also not entirely true because if your service provider promises an internet speed of 100 Mbps, you may not really get 100 Mbps all the time. That’s the maximum bandwidth you get for all the connected devices. Moreover, your file download speed is also affected by the server you are downloading from.

To avoid confusion between Mbps (internet speed) and MBps (file transfer speed), MBps is often written as MB/s.

This Mbps to MBps converter is a simple tool. It helps you learn that if your file download speed is displaying in Mbps, how long will it really take to download a file of certain MB.

The conversion formula is simple if you can recall the basics:

  • Mbps: Megabit per second (Mbps)
  • MBps: Megabyte per second (MBps or MB/s)
  • 1 Byte = 8 bits
  • 1 MBps = 8 Mbps
  • 1 Mbps = 0.125 MBps
