Gbps to GB/s formula and what each symbol means
GB/s = Gbit/s × 0.125
| Symbol | Meaning |
|---|---|
| Gbit/s | Gigabit per second |
| GB/s | Gigabyte per second |
Gbps to GB/s examples
1 Gbit/s
1 Gbit/s × 0.125 = 0.125 GB/s.
10 Gbit/s
10 Gbit/s × 0.125 = 1.25 GB/s.
100 Gbit/s
100 Gbit/s × 0.125 = 12.5 GB/s.
Gbps compared with GB/s
One GB/s is 8 times as large as one Gbit/s, so your number gets smaller when you convert gbps to GB/s and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About gbps and GB/s
Gigabit per second (Gbit/s): One billion bits per second. Gigabyte per second (GB/s): One billion bytes per second.
Where gbps to GB/s conversions are used
Storage interfaces such as SATA, NVMe and USB list rates in MB/s or Gbps. Internet plans are sold in megabits per second, while downloads display megabytes per second.
How to calculate Gbps to GB/s step by step
- Enter the value in Gbit/s (the starting unit).
- Multiply by 0.125, because 1 Gbit/s = 0.125 GB/s.
- The product is the value in GB/s. To go back, divide by 0.125 or multiply by 8.

Common mistakes when calculating Gbps to GB/s
- Mixing decimal (MB/s) and binary (MiB/s) units.
- Dividing when you should multiply: from Gbit/s to GB/s multiply by 0.125; from GB/s to Gbit/s divide by 0.125.
Gbps to GB/s FAQ
How many GB/s are in 1 Gbit/s?
1 Gbit/s equals 0.125 GB/s.
How many Gbit/s are in 1 GB/s?
1 GB/s equals 8 Gbit/s.
Is 1 Gbit/s = 0.125 GB/s an exact conversion?
Yes. The gigabit per second and the gigabyte per second are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 0.125 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 gbps to GB/s in my head?
One GB/s is 8 times as large as one Gbit/s, so your number gets smaller when you convert gbps to GB/s and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 75 Gbit/s in GB/s?
75 Gbit/s = 9.375 GB/s (since 75 × 0.125).
What is 300 Gbit/s in GB/s?
300 Gbit/s = 37.5 GB/s (since 300 × 0.125).
What is 12 Gbit/s in GB/s?
12 Gbit/s = 1.5 GB/s (since 12 × 0.125).
How many decimals should I keep when converting Gbit/s to GB/s?
Match the precision of your original measurement. For example, 1.25 GB/s rounds to 1.25 GB/s at 3 significant figures; keep more digits only for engineering or scientific work.
