Mbps to Gbps Converter

One gigabit per second is 1,000 megabits per second. Fibre broadband and network switches are often marketed in Gbps.

How to use the Mbps to Gbps Converter

1. Type the number of megabits per second into the Megabits per second field. Decimals such as 500 are fine.
2. Read the answer in Gigabits per second. It updates as you type, with no button to press. The same amount is also shown in MB/s, kbit/s.
3. To go from gigabits per second back to megabits per second, type into the Gigabits per second field instead. Every field also has a unit menu with all 9 data rate units, for example bit/s, kbit/s, B/s, kB/s, MB/s, GB/s.

Results update as you type, and everything is calculated in your browser.

How it works

Both units measure data rate, so they are always in the same ratio: one megabit per second equals 0.001 gigabits per second. The calculator multiplies the number of megabits per second you type by 0.001 to give gigabits per second, and when you type into the gigabits per second field it divides by the same factor to give megabits per second. Because the ratio never changes, doubling the megabits per second always doubles the gigabits per second, for example 2,000 Mbit/s is 2 Gbit/s.

How to convert megabits per second to gigabits per second

1. Write down the value in megabits per second, for example 1,000 Mbit/s.
2. Multiply by the conversion factor 0.001 (because 1 megabit per second = 0.001 Gbit/s).
3. 1,000 × 0.001 = 1 Gbit/s.
4. To go back from gigabits per second to megabits per second, divide by 0.001, or multiply by 1,000.

Data rate units explained

Megabit per second (Mbit/s)

Megabits per second (Mbps) is the unit internet providers use to sell connection speed. Divide by 8 for megabytes per second.

Gigabit per second (Gbit/s)

Gigabits per second (Gbps) is 1,000 Mbps, used for fibre broadband and network equipment.

Common mistakes to avoid

Reading Mbps (megabits) as MB/s (megabytes); divide megabits by 8 to get megabytes.
