Mbps to MB/s Converter

Calculate your actual file download speed from your advertised internet bandwidth.

How to convert Mbps to MB/s

  • 1Enter your internet speed in Mbps
  • 2Divide the number by 8
  • 3The result is your actual download speed in MB/s
MB/s = Mbps ÷ 8

Converting Mbps to MB/s: What You Need to Know

When you sign up for a new internet plan, the speed is almost always advertised in Megabits per second (Mbps). However, when you use a download time calculator or download a game, your computer shows the speed in Megabytes per second (MB/s).

Why the difference? Bits (b) are used by networking equipment to measure data transfer speed, while Bytes (B) are used by computers to measure file sizes.

Since there are 8 bits in a byte, you must divide your internet speed by 8 to find your actual download speed.

For example, if you have a 100 Mbps internet connection, your maximum theoretical download speed is 100 / 8 = 12.5 MB/s. To calculate the reverse, use our MB/s to Mbps converter.

Frequently Asked Questions

Why divide by 8 to get MB/s?
Because there are 8 bits in one Byte. ISPs advertise speeds in Megabits (Mbps), but computers save files in Megabytes (MB/s). So dividing by 8 gives you your actual download speed.
Is 100 Mbps the same as 100 MB/s?
No, they are very different. 100 Mbps (Megabits per second) equals 12.5 MB/s (Megabytes per second). A 100 MB/s download speed would require an 800 Mbps internet connection.
What is a good Mbps speed for home internet?
For a family of four using streaming services, gaming, and working from home, a connection of 300 Mbps (which equals 37.5 MB/s) is generally considered excellent.
How many MB/s is 1 Gbps?
1 Gbps is 1000 Mbps. When you divide 1000 by 8, you get a maximum theoretical download speed of 125 MB/s.
Why is my speed test showing Mbps?
Speed tests measure network throughput, which has traditionally always been measured in bits. File managers use Bytes because they measure data storage capacity.
