Convert Megabits per Second (Mbps) to Megabytes per Second (MB/s)
Your internet plan is sold in megabits per second (Mbps), but downloads show megabytes per second (MB/s) — and the difference is a factor of 8. 100 Mbps equals just 12.5 MB/s.
Formula
1 Mbps = 0.125 MB/s
To convert Mbps to MB/s, divide the value by 8.

Common Mbps to MB/s Examples
- 1 Mbps = 0.125 MB/s
- 5 Mbps = 0.625 MB/s
- 10 Mbps = 1.25 MB/s
- 25 Mbps = 3.125 MB/s
- 50 Mbps = 6.25 MB/s
- 100 Mbps = 12.5 MB/s
- 500 Mbps = 62.5 MB/s
- 1000 Mbps = 125 MB/s
About Mbps to MB/s
A byte is 8 bits, so divide Mbps by 8 to get MB/s: 50 Mbps → 6.25 MB/s, 300 Mbps → 37.5 MB/s, 1000 Mbps (gigabit) → 125 MB/s. This is why a "100 meg" connection downloads a 6 GB file in about 8 minutes, not one.
If your download speed looks lower than advertised, check the units first: a browser showing 11–12 MB/s on a 100 Mbps line is actually delivering full speed. Real-world throughput also loses a few percent to protocol overhead, so 94–95% of the nominal figure is normal.
Frequently Asked Questions
How many MB/s is 100 Mbps?
12.5 MB/s. Divide megabits per second by 8, because one byte is 8 bits.
Why is my download in MB/s slower than my plan in Mbps?
They are different units: a 200 Mbps plan can never exceed 25 MB/s. Seeing about 23–24 MB/s means the connection is performing normally after protocol overhead.
Where does the unit MB/s come from?
Megabytes per Second is a Data Transfer Rate unit with its own historical and regional roots, now defined in relation to internationally agreed reference standards.
Where does the unit Mbps come from?
Megabits per Second is a standard Data Transfer Rate unit used in specific regions or fields. Its definition has been refined over time to match international measurement standards.
What is the formula to convert Mbps to MB/s?
The formula is 1 Mbps = 0.125 MB/s. To convert any value, divide the value by 8.
How much is 1 Mbps in MB/s?
1 Mbps equals 0.125 MB/s. This ratio applies to every conversion between the two units.
Is the conversion from Mbps to MB/s exact?
The ratio 0.125 is defined to high precision and is exact for most practical purposes. Rounding only matters when many decimal places are needed.
How do I convert Mbps to MB/s by hand?
Take the value in Mbps and divide the value by 8. The result is the same value expressed in MB/s.
