How to convert megabits per second to gigabits per second
Worked example: convert 12 megabits per second to gigabits per second. Using gigabits per second ← megabits per second ÷ 1,000, we get 12 × 0.001 = 0.012 Gbps. To check the result, convert back: 0.012 Gbps ÷ 0.001 = 12 Mbps.

About the megabit per second and the gigabit per second
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.
Gigabits per second is used for fiber internet, Ethernet and Wi-Fi 6 link rates. One Gbps is 1,000 Mbps.
One gigabit per second equals 1,000 megabits per second, which makes the gigabit per second the faster unit of the two.
Everyday sizes in megabits per second and gigabits per second
| Everyday example (approximate) | In megabits per second | In gigabits per second |
|---|---|---|
| HD video streaming | 5 Mbps | 0.005 Gbps |
| 4K video streaming | 25 Mbps | 0.025 Gbps |
| A basic broadband plan | 100 Mbps | 0.1 Gbps |
| Gigabit fiber | 1,000 Mbps | 1 Gbps |
| A fast SATA SSD | 4,400 Mbps | 4.4 Gbps |
| Wi-Fi 6 top link rate | 9,600 Mbps | 9.6 Gbps |
Megabits per second to gigabits per second FAQ
How many gigabits per second are in one megabit per second?
One megabit per second equals exactly 0.001 gigabits per second. In the other direction, one gigabit per second equals 1,000 megabits per second.
How do I convert megabits per second to gigabits per second without a calculator?
convert 12 megabits per second to gigabits per second. Using gigabits per second ← megabits per second ÷ 1,000, we get 12 × 0.001 = 0.012 Gbps. To check the result, convert back: 0.012 Gbps ÷ 0.001 = 12 Mbps. For a quick estimate, round the factor to 0.001. Then 12 Mbps is about 0.012 Gbps, compared with the exact 0.012 Gbps (an error of 0%). That is close enough for planning, but use the calculator above when the number matters.
What is hD video streaming in gigabits per second?
HD video streaming is about 5 megabits per second, which is 0.005 gigabits per second. Treat that as an approximate everyday figure rather than an official measurement.
Are the megabits per second and gigabits per second the same in every country?
Mbps (megabits) is not MB/s (megabytes): the byte version is 8 times larger. One Gbps is exactly 1,000 Mbps (decimal prefixes are used for network speeds).
