How many kbps are in 1 Gbps?

1 gigabit per second equals exactly 1,000,000 kilobits per second using the SI (decimal) prefix system. This is the standard used by ISPs and networking equipment vendors: 1 Gbps = 1,000 Mbps = 1,000,000 kbps.

Is Gbps the same as GB/s?

No. Gbps (gigabits per second) measures data rate in bits. GB/s (gigabytes per second) measures in bytes. Since 1 byte = 8 bits, 1 GB/s = 8 Gbps. This tool converts between Gbps and kbps only.

Why does my 1 Gbps connection show only ~940 Mbps in tests?

Protocol overhead (TCP/IP headers, Ethernet framing) consumes a few percent of raw capacity. A "1 Gbps" port can deliver roughly 940–960 Mbps of usable throughput, which equals roughly 940,000–960,000 kbps.

How do I convert kbps to Mbps or Gbps?

Divide kbps by 1,000 for Mbps, or by 1,000,000 for Gbps. For example, 500,000 kbps = 500 Mbps = 0.5 Gbps. Use the reverse field on this page to go directly from kbps to Gbps.

Summary

This tool converts gigabits per second (Gbps) to kilobits per second (kbps) using the SI decimal standard, where 1 Gbps equals exactly 1,000,000 kbps. It is useful when comparing fiber optic link speeds with legacy DSL or cable quotations, or when network monitoring tools report throughput in different units. Enter any Gbps value for an immediate result, or use the reverse field to convert kbps back to Gbps.

How it works

Type a value in gigabits per second (Gbps) into the top input field.
The converter multiplies your value by 1,000,000 to produce kilobits per second.
The result updates instantly as you type — no button required.
Use the reverse field to convert kbps back to Gbps.
Click the copy button next to any result to copy it to your clipboard.

Use cases

Compare a 10 Gbps fiber uplink to a plan quoted in kbps.
Translate backbone throughput figures from network monitoring dashboards.
Verify ISP speed tier marketing (e.g. "1 Gbps" = 1,000,000 kbps).
Convert hardware NIC speeds to kbps for legacy reporting systems.
Cross-check cable modem or DSL aggregation capacity in consistent units.
