Gbps to MB/s formula and what each symbol means
MB/s = Gbit/s × 125
| Symbol | Meaning |
|---|---|
| Gbit/s | Gigabit per second |
| MB/s | Megabyte per second |
Gbps to MB/s examples
1 Gbit/s
1 Gbit/s × 125 = 125 MB/s.
10 Gbit/s
10 Gbit/s × 125 = 1,250 MB/s.
100 Gbit/s
100 Gbit/s × 125 = 12,500 MB/s.
Gbps compared with MB/s
One Gbit/s is 125 times as large as one MB/s, so your number gets bigger when you convert gbps to MB/s and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About gbps and MB/s
Gigabit per second (Gbit/s): One billion bits per second. Megabyte per second (MB/s): One million bytes per second, 8 Mbit/s.
Where gbps to MB/s conversions are used
Network equipment, Wi-Fi and fibre links are rated in Mbps or Gbps. Storage interfaces such as SATA, NVMe and USB list rates in MB/s or Gbps.
How to calculate Gbps to MB/s step by step
- Enter the value in Gbit/s (the starting unit).
- Multiply by 125, because 1 Gbit/s = 125 MB/s.
- The product is the value in MB/s. To go back, divide by 125 or multiply by 0.008.

Common mistakes when calculating Gbps to MB/s
- Expecting to download at the advertised line speed: protocol overhead lowers real throughput.
- Dividing when you should multiply: from Gbit/s to MB/s multiply by 125; from MB/s to Gbit/s divide by 125.
Gbps to MB/s FAQ
How many MB/s are in 1 Gbit/s?
1 Gbit/s equals 125 MB/s.
How many Gbit/s are in 1 MB/s?
1 MB/s equals 0.008 Gbit/s.
Is 1 Gbit/s = 125 MB/s an exact conversion?
Yes. The gigabit per second and the megabyte per second are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 125 is just that ratio shown to 7 significant figures.
What is a gigabit per second (Gbit/s)?
One billion bits per second.
How can I estimate gbps to MB/s in my head?
One Gbit/s is 125 times as large as one MB/s, so your number gets bigger when you convert gbps to MB/s and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 30 Gbit/s in MB/s?
30 Gbit/s = 3,750 MB/s (since 30 × 125).
What is 150 Gbit/s in MB/s?
150 Gbit/s = 18,750 MB/s (since 150 × 125).
What is 0.5 Gbit/s in MB/s?
0.5 Gbit/s = 62.5 MB/s (since 0.5 × 125).
How many decimals should I keep when converting Gbit/s to MB/s?
Match the precision of your original measurement. For example, 1,250 MB/s rounds to 1,250 MB/s at 3 significant figures; keep more digits only for engineering or scientific work.
