How many Gbps is 1 GB/s?

1 GB/s equals 8 Gbps. This is because 1 byte = 8 bits, so you multiply the GB/s value by 8 to get Gbps.

What is the difference between GB/s and Gbps?

GB/s (gigabytes per second) measures data in bytes; Gbps (gigabits per second) measures data in bits. Since 1 byte = 8 bits, 1 GB/s = 8 Gbps. Storage devices commonly use GB/s while network speeds use Gbps.

Why do storage and networking use different units?

Storage manufacturers historically quoted throughput in bytes per second because files are measured in bytes. Networking standards use bits per second because serial links transmit one bit at a time. Both are valid; just keep the factor-of-8 difference in mind when comparing them.

Is this converter using SI (decimal) or binary gigabytes?

It uses SI (decimal) gigabytes where 1 GB = 1,000,000,000 bytes and 1 Gbps = 1,000,000,000 bits. Most storage specs and all networking specs use this convention. Binary gibibytes (GiB) use a different base and are not standard in networking contexts.

How do I convert Gbps back to GB/s?

Divide Gbps by 8 to get GB/s. For example, 40 Gbps ÷ 8 = 5 GB/s. Use the swap button in this tool to do that automatically.

Summary

Convert gigabytes per second (GB/s) to gigabits per second (Gbps) instantly. Formula: Gbps = GB/s × 8.

How it works

Enter a value in gigabytes per second (GB/s) in the input field.
The converter multiplies your value by 8 (since 1 byte = 8 bits) to get Gbps.
The result appears instantly in the Gbps output field.
Use the swap button to reverse the conversion from Gbps back to GB/s.
Copy either result to the clipboard with one click.
Use the reset button to clear both fields and start over.

Use cases

Compare NVMe SSD throughput (e.g. 7 GB/s) against a 40 Gbps network uplink.
Check whether a storage array can saturate a 100 Gbps backbone link.
Convert memory bandwidth figures from GB/s to Gbps for architecture documents.
Verify that a PCIe Gen 4 x4 link (about 7.88 GB/s) fits within a 100 Gbps switch port.
Convert cloud storage egress rates quoted in GB/s to Gbps for billing comparisons.
Plan data migration timelines by matching disk throughput to network transfer rates.
