Gigabits per second to Megabytes per second Converter
1 Gbit/s equals 125 MB/s, and 1 MB/s equals 0.008 Gbit/s. Enter a value in either box to convert gigabits per second to megabytes per second and back. Formula: bits per second = value x unit factor (1 byte = 8 bits; decimal prefixes 1 Mbit/s = 1,000,000 bit/s).

Gigabits per second to Megabytes per second Conversion Table
| Gigabits per second | Megabytes per second |
|---|---|
| 1 Gbit/s | 125 MB/s |
| 8 Gbit/s | 1,000 MB/s |
| 10 Gbit/s | 1,250 MB/s |
| 25 Gbit/s | 3,125 MB/s |
| 50 Gbit/s | 6,250 MB/s |
| 100 Gbit/s | 12,500 MB/s |
| 250 Gbit/s | 31,250 MB/s |

Megabytes per second to Gigabits per second Conversion Table
| Megabytes per second | Gigabits per second |
|---|---|
| 1 MB/s | 0.008 Gbit/s |
| 8 MB/s | 0.064 Gbit/s |
| 10 MB/s | 0.08 Gbit/s |
| 25 MB/s | 0.2 Gbit/s |
| 50 MB/s | 0.4 Gbit/s |
| 100 MB/s | 0.8 Gbit/s |
| 250 MB/s | 2 Gbit/s |
| 500 MB/s | 4 Gbit/s |
| 1,000 MB/s | 8 Gbit/s |
Worked example: 10 Gbit/s = 1,250 MB/s. A 100 Mbit/s plan is 100 / 8 = 12.5 MB/s, so a 1 GB file needs at least 1,000 / 12.5 = 80 seconds.

Formula
bits per second = value x unit factor (1 byte = 8 bits; decimal prefixes 1 Mbit/s = 1,000,000 bit/s)Understanding Data Transfer Rate Conversion
Internet plans quote speed in megabits or gigabits per second, while browsers and download managers show megabytes per second. Because a byte is eight bits, a 100 Mbit/s connection can move at most 12.5 MB/s. Real throughput is lower because of protocol overhead, Wi-Fi conditions and server limits, so treat the converted figure as the ceiling rather than the speed you will see in practice.
Tips and Best Practices
- 1Divide megabits per second by 8 to get megabytes per second.
- 2A gigabit connection tops out near 125 MB/s in theory.
- 3Lowercase b is bits and uppercase B is bytes; check which one a plan or app uses.
Real-World Example
A 100 Mbit/s plan is 100 / 8 = 12.5 MB/s, so a 1 GB file needs at least 1,000 / 12.5 = 80 seconds.
Common Mistakes to Avoid
- Comparing a Mbit/s plan to an MB/s download figure without dividing by 8.
- Assuming advertised speed equals measured speed.
- Using binary prefixes for network rates; network rates are decimal by convention.
How to Use
- Type a number in the Gigabits per second box.
- The Megabytes per second result appears instantly; you can also edit the Megabytes per second box to convert backwards.
- Use the swap button to reverse the direction and Copy result to copy the answer.
