Download Time Calculator
Estimates how long a file takes to download at a given speed.
Mbps to MB/s Converter
Convert Mbps to MB/s to see what your internet plan means in the units a download manager shows. It also converts Kbps, Gbps, KB/s, GB/s, and MiB/s.

How to use the Mbps to MB/s Converter
- Enter the Value of the speed. Decimals are allowed.
- Pick its Unit, such as Mbps for an internet plan or MB/s for a download manager.
- Press Convert. The main result is MB/s for bit-based units and Mbps for byte-based units, with every other unit listed underneath. Use Swap to reverse the direction.
How it works
The speed is converted to bits per second, then to each unit.
| Unit | Bits per second |
|---|---|
| Kbps | 10^3 |
| Mbps | 10^6 |
| Gbps | 10^9 |
| KB/s | 8 × 10^3 |
| MB/s | 8 × 10^6 |
| GB/s | 8 × 10^9 |
| MiB/s | 8 × 2^20 |
So Mbps ÷ 8 = MB/s, and MB/s × 8 = Mbps.
Examples
- 100 Mbps = 12.5 MB/s = 11.92 MiB/s.
- 1 Gbps = 125 MB/s.
- 50 MB/s = 400 Mbps.
Common internet plans in MB/s
| Plan | MB/s | MiB/s |
|---|---|---|
| 10 Mbps | 1.25 | 1.19 |
| 25 Mbps | 3.125 | 2.98 |
| 50 Mbps | 6.25 | 5.96 |
| 100 Mbps | 12.5 | 11.92 |
| 300 Mbps | 37.5 | 35.76 |
| 500 Mbps | 62.5 | 59.6 |
| 1,000 Mbps | 125 | 119.21 |
| 2,500 Mbps | 312.5 | 298.02 |
These are the maximum rates before network overhead.
Limitations
- Negative values give an error.
- Some download managers show binary MiB/s but label it "MB/s", which makes the speed look about 5% lower than the figures here.
- The results are ideal rates. Real transfers are slower because of overhead, Wi-Fi, and congestion.
Frequently asked questions
How do I convert Mbps to MB/s?
Divide by 8, because one byte is 8 bits. For example, 100 Mbps ÷ 8 = 12.5 MB/s.
What is the difference between Mbps and MBps?
Mbps (lowercase b) is megabits per second, used for internet plans. MBps or MB/s (uppercase B) is megabytes per second, used for download speeds and file sizes.
What is 1 Gbps in MB/s?
125 MB/s, in ideal conditions before any network overhead.
Why is my download slower than my plan?
Overhead, Wi-Fi, congestion, and server limits all reduce the real speed. The Download Time Calculator has an overhead option for a realistic estimate.
