How to convert gigabits per second to megabits per second
Worked example: convert 512 gigabits per second to megabits per second. Using megabits per second ← gigabits per second × 1,000, we get 512 × 1,000 = 512,000 Mbps. To check the result, convert back: 512,000 Mbps ÷ 1,000 = 512 Gbps.

About the gigabit per second and the megabit per second
Gigabits per second is used for fiber internet, Ethernet and Wi-Fi 6 link rates. One Gbps is 1,000 Mbps.
Megabits per second is the unit internet providers use to advertise speed. A bit is one eighth of a byte, so 8 Mbps moves 1 MB of data each second.
One gigabit per second is 1,000 times the size of one megabit per second, so it takes fewer gigabits per second than megabits per second to express the same amount.
Everyday sizes in gigabits per second and megabits per second
| Everyday example (approximate) | In gigabits per second | In megabits per second |
|---|---|---|
| HD video streaming | 0.005 Gbps | 5 Mbps |
| 4K video streaming | 0.025 Gbps | 25 Mbps |
| A basic broadband plan | 0.1 Gbps | 100 Mbps |
| Gigabit fiber | 1 Gbps | 1,000 Mbps |
| A fast SATA SSD | 4.4 Gbps | 4,400 Mbps |
| Wi-Fi 6 top link rate | 9.6 Gbps | 9,600 Mbps |
Gigabits per second to megabits per second FAQ
How many megabits per second are in one gigabit per second?
One gigabit per second equals exactly 1,000 megabits per second. In the other direction, one megabit per second equals 0.001 gigabits per second.
How do I convert gigabits per second to megabits per second without a calculator?
convert 512 gigabits per second to megabits per second. Using megabits per second ← gigabits per second × 1,000, we get 512 × 1,000 = 512,000 Mbps. To check the result, convert back: 512,000 Mbps ÷ 1,000 = 512 Gbps. For a quick estimate, round the factor to 1,000. Then 512 Gbps is about 512,000 Mbps, compared with the exact 512,000 Mbps (an error of 0%). That is close enough for planning, but use the calculator above when the number matters.
What is a basic broadband plan in megabits per second?
A basic broadband plan is about 0.1 gigabits per second, which is 100 megabits per second. Treat that as an approximate everyday figure rather than an official measurement.
Are the gigabits per second and megabits per second the same in every country?
One Gbps is exactly 1,000 Mbps (decimal prefixes are used for network speeds). Mbps (megabits) is not MB/s (megabytes): the byte version is 8 times larger.
