Megabits per Second to Gigabits per Second Converter
1,000 Mbps = 1 Gbps
Whether you are working in computing or networking, converting from megabytes to gigabytes is a task you will encounter regularly. The megabyte became common in the 1980s with personal computers. For quick reference, 1 MB equals 0.001 GB.
Did you know? Did you know? The megabyte is commonly used for photo files, short audio clips, software downloads, and document sizes. A standard HD movie file is about 4 to 5 gigabytes - and knowing the conversion between these two units makes working across measurement systems effortless.
Conversion Formula
Gbps = Mbps / 1,000
To convert Mbps to Gbps, divide by 1,000. Both are units of data transfer rate measured in bits per second, with the SI prefix scaling.

About Megabytes to Gigabytes
The Mbps-to-Gbps conversion is increasingly relevant as internet speeds and network infrastructure move into the gigabit era. Understanding these units helps evaluate internet plans and network equipment.
Consumer internet context: basic broadband starts at 25 Mbps (0.025 Gbps). Most cable internet plans offer 100-300 Mbps (0.1-0.3 Gbps). Fiber plans commonly offer 500 Mbps to 1 Gbps (1,000 Mbps). The fastest residential plans reach 2-10 Gbps.
At 100 Mbps (0.1 Gbps), you can download a 1 GB file in about 80 seconds. At 1 Gbps, the same file downloads in 8 seconds. At 10 Gbps, it takes less than 1 second.
Data center networking operates at much higher speeds. Server connections are typically 1-25 Gbps (1,000-25,000 Mbps). Backbone connections between data centers use 100-400 Gbps links. Google's internal network operates at terabits per second.
WiFi standards illustrate the progression: WiFi 5 (802.11ac) theoretically supports up to 3,500 Mbps (3.5 Gbps). WiFi 6 (802.11ax) reaches 9,600 Mbps (9.6 Gbps). WiFi 7 promises up to 46,000 Mbps (46 Gbps). Real-world speeds are typically 30-50% of theoretical maximums.
Important: Mbps (megabits) and MBps (megabytes) are different. 1 byte = 8 bits, so 100 Mbps = 12.5 MBps download speed.
Frequently Asked Questions
How many Mbps is 1 Gbps?
1 Gbps equals 1,000 Mbps. A gigabit internet connection provides 1,000 megabits per second of bandwidth.
Is 100 Mbps fast enough for streaming?
Yes. Netflix recommends 25 Mbps for 4K streaming. 100 Mbps (0.1 Gbps) can support multiple simultaneous 4K streams plus other devices.
What is the difference between Mbps and MBps?
Mbps = megabits per second (lowercase b). MBps = megabytes per second (uppercase B). 1 byte = 8 bits, so 100 Mbps = 12.5 MBps. Internet speeds use Mbps; file downloads often show MBps.
How fast is gigabit internet in real-world use?
A 1 Gbps plan typically delivers 800-940 Mbps actual speeds. This allows downloading a 4K movie (20 GB) in about 3 minutes, or a full game (100 GB) in about 15 minutes.
