How many kbps is 1 GB/s?

1 GB/s equals 8,000,000 kbps. The factor comes from two steps: 1 GB = 1,000 MB = 1,000,000 KB, and 1 byte = 8 bits, so 1 GB/s = 1,000,000 KB/s × 8 bits = 8,000,000 kbps.

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

This tool uses SI decimal gigabytes (1 GB = 10^9 bytes = 1,000,000,000 bytes), which is standard for network speeds. If you need GiB/s (gibibytes, 1 GiB = 2^30 bytes), multiply the GB/s result by 1000/1024 × 1000/1024.

My ISP quotes speed in Mbps, not kbps. Can I still use this?

Yes — first multiply your Mbps value by 1,000 to get kbps, then enter that number. For example, 500 Mbps = 500,000 kbps ≈ 0.0000625 GB/s.

Why is the GB/s number so small for typical internet speeds?

Consumer broadband (10–1,000 Mbps = 10,000–1,000,000 kbps) translates to only 0.00000125–0.000125 GB/s. GB/s is a unit suited for internal storage buses (PCIe, RAM) that run at thousands of Mbps.

What is the difference between kbps and KB/s?

kbps (kilobits per second) is 1,000 bits/s. KB/s (kilobytes per second) is 1,000 bytes/s = 8,000 bits/s. They differ by a factor of 8. Download managers often show KB/s while routers show kbps.

Enter a speed in kbps and instantly get the equivalent in GB/s (1 GB/s = 8,000,000 kbps).

Convert Speed

Kilobits per second (kbps)

Gigabytes per second (GB/s)

Reference Values

Speed (kbps)	GB/s

Formula

GB/s = kbps ÷ 8,000,000

1 GB = 1,000,000 KB = 8,000,000 kbit (SI decimal)

Summary

Enter a speed in kbps and instantly get the equivalent in GB/s (1 GB/s = 8,000,000 kbps).

How it works

Enter a value in kilobits per second (kbps) in the input field.
The tool divides by 8,000,000 to convert to gigabytes per second.
Results appear instantly — no button click needed.
Use the swap button to reverse the conversion (GB/s to kbps).
Copy the result with one click.

Use cases

Check if a network link can sustain a target GB/s throughput.
Compare ISP speed tiers quoted in kbps against storage bandwidth in GB/s.
Estimate how fast a backup job runs when link speed is given in kbps.
Convert benchmark results between data-rate units for reports.
Verify NIC or SSD specs stated in different unit systems.
