Gigabytes per Second to Bytes per Second (GB/s to B/s)
1 gigabyte per second (GB/s) = 1000000000 bytes per second (B/s). 1 B/s = 1 × 10⁻⁹ GB/s. Example: 15 GB/s = 15 × 1000000000 = 15000000000 B/s.

How to Convert Gigabyte per Second to Byte per Second
- 1 GB/s = 1000000000 B/s
- 1 B/s = 1 × 10⁻⁹ GB/s
- Example: convert 15 GB/s to B/s: 15 GB/s = 15 × 1000000000 B/s = 15000000000 B/s
Formula
B/s = GB/s × 1000000000
Derivation from SI units:
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 B/s = 8 bit/s.
- 1 GB/s = 8000000000 bps ÷ 8 bps per B/s = 1000000000 B/s
Both units are defined exactly, so the factor is exact. Gigabyte per Second definition: gigabyte per second; Byte per Second definition: byte per second.
Worked examples
- A reading of 2 GB/s converts to 2000000000 B/s.
2 GB/s × 1000000000 = 2000000000 B/s - A value of 7 GB/s is 7000000000 B/s.
7 GB/s × 1000000000 = 7000000000 B/s

Frequently asked questions
How many bytes per second are in 1 gigabyte per second?
1 GB/s = 1000000000 B/s.
How do I convert gigabytes per second to bytes per second?
Multiply the value in GB/s by 1000000000. For example, 15 GB/s × 1000000000 = 15000000000 B/s.
