How many Mbps is 1 Gbps?

1 Gbps equals 1000 Mbps. Data rates use decimal SI units, so multiply gigabits by 1000 to get megabits. A 2.5 Gbps link is 2500 Mbps.

Should I use 1000 or 1024 to convert?

Use 1000. Data transfer rates (Gbps, Mbps) are decimal — 1 Gbps = 1000 Mbps. The 1024 (binary) convention applies to storage capacity like GiB, not to link speeds.

How do I convert Mbps back to Gbps?

Divide megabits per second by 1000. For example, 2500 Mbps ÷ 1000 = 2.5 Gbps. Switch the direction selector to convert this way.

How many MB/s is 1 Gbps?

About 125 MB/s. Megabits convert to megabytes by dividing by 8, so 1000 Mbps ÷ 8 = 125 MB/s of real file throughput.

What is 2.5 Gbps in Mbps?

2.5 Gbps equals 2500 Mbps (2.5 × 1000). That's the speed of common multi-gig fibre and 2.5GbE ports.

Why divide by 8 for MB/s?

There are 8 bits in a byte. Link speeds are quoted in bits per second, but file sizes are in bytes, so you divide the megabit rate by 8 to get megabytes per second.

Is my data sent anywhere?

No. The converter is privacy-first and runs entirely in your browser — nothing you enter leaves your device.

This free converter turns gigabit-per-second (Gbps) network and internet link speeds into megabits per second (Mbps) and back, and also shows the equivalent file-transfer throughput in MB/s. It is handy for comparing fibre plans, switch ports, and data-centre uplinks quoted in different units.

How it works

Data transfer rates use decimal SI units, not the binary (1024) convention used for storage capacity. The gigabit-to-megabit conversion is a simple factor of 1,000:

Mbps = Gbps × 1000 (and Gbps = Mbps ÷ 1000)

To estimate real file throughput, the tool divides the megabit figure by 8 — because there are 8 bits in a byte:

MB/s = Mbps ÷ 8

Speed reference table

Link speed	Megabits/s	Megabytes/s	Typical use case
100 Mbps	100 Mbps	12.5 MB/s	Fast Ethernet port
0.5 Gbps	500 Mbps	62.5 MB/s	Basic 500M broadband
1 Gbps	1,000 Mbps	125 MB/s	Gigabit fibre, 1GbE NIC
2.5 Gbps	2,500 Mbps	312.5 MB/s	2.5GbE (common in modern routers)
10 Gbps	10,000 Mbps	1,250 MB/s	10GbE switch port or NAS uplink
25 Gbps	25,000 Mbps	3,125 MB/s	Data-centre server NIC
100 Gbps	100,000 Mbps	12,500 MB/s	Data-centre backbone

Why MB/s matters more than Mbps for most people

Internet plans and switch ports are marketed in Mbps or Gbps, but the files on your computer are measured in megabytes (MB) or gigabytes (GB). The divide-by-8 conversion bridges those worlds:

A 1 Gbps fibre plan downloads at up to 125 MB/s — a 1 GB file in about 8 seconds under ideal conditions.
A 100 Mbps cable connection maxes out at 12.5 MB/s — that same 1 GB file takes about 80 seconds.
A 10 Gbps NAS uplink can sustain up to 1,250 MB/s — limited in practice by the NAS drive speed, not the network.

Common gotchas

Advertised vs real speed. ISP speeds are “up to” figures measured on a clean connection. Protocol overhead (TCP/IP headers, encryption for HTTPS, etc.) typically eats 3–5% of raw bandwidth. Real download speeds are usually 85–95% of the link rate.

Half-duplex limitations. Older Wi-Fi standards and some copper Ethernet links are half-duplex — you cannot send and receive at full speed simultaneously. Gigabit Ethernet and Wi-Fi 5/6 are full-duplex.

NIC and switch bottlenecks. A 2.5 Gbps capable router connected to a laptop with a 1GbE NIC still maxes at 1 Gbps. The slowest link in the chain sets the ceiling.
