Use the GB/s to Mbps Converter
GB/s to Mbps formula and what each symbol means
Mbit/s = GB/s × 8,000
| Symbol | Meaning |
|---|---|
| GB/s | Gigabyte per second |
| Mbit/s | Megabit per second |
GB/s to Mbps examples
1 GB/s
1 GB/s × 8,000 = 8,000 Mbit/s.
10 GB/s
10 GB/s × 8,000 = 80,000 Mbit/s.
100 GB/s
100 GB/s × 8,000 = 800,000 Mbit/s.
GB/s compared with Mbps
One GB/s is 8,000 times as large as one Mbit/s, so your number gets bigger when you convert GB/s to mbps and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About GB/s and mbps
Gigabyte per second (GB/s): One billion bytes per second. Megabit per second (Mbit/s): One million bits per second.
Where GB/s to mbps 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 GB/s to Mbps step by step
- Enter the value in GB/s (the starting unit).
- Multiply by 8,000, because 1 GB/s = 8,000 Mbit/s.
- The product is the value in Mbit/s. To go back, divide by 8,000 or multiply by 0.000125.

Common mistakes when calculating GB/s to Mbps
- Expecting to download at the advertised line speed: protocol overhead lowers real throughput.
- Dividing when you should multiply: from GB/s to Mbit/s multiply by 8,000; from Mbit/s to GB/s divide by 8,000.
GB/s to Mbps FAQ
How many Mbit/s are in 1 GB/s?
1 GB/s equals 8,000 Mbit/s.
How many GB/s are in 1 Mbit/s?
1 Mbit/s equals 0.000125 GB/s.
Is 1 GB/s = 8,000 Mbit/s an exact conversion?
Yes. The gigabyte per second and the megabit per second are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 8,000 is just that ratio shown to 7 significant figures.
What is a gigabyte per second (GB/s)?
One billion bytes per second.
How can I estimate GB/s to mbps in my head?
One GB/s is 8,000 times as large as one Mbit/s, so your number gets bigger when you convert GB/s to mbps and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 0.5 GB/s in mbps?
0.5 GB/s = 4,000 Mbit/s (since 0.5 × 8,000).
What is 25 GB/s in mbps?
25 GB/s = 200,000 Mbit/s (since 25 × 8,000).
What is 80 GB/s in mbps?
80 GB/s = 640,000 Mbit/s (since 80 × 8,000).
How many decimals should I keep when converting GB/s to Mbit/s?
Match the precision of your original measurement. For example, 80,000 Mbit/s rounds to 80,000 Mbit/s at 3 significant figures; keep more digits only for engineering or scientific work.
