Convert megabits per second (Mbps) to gigabits per second (Gbps), or switch directions to convert Gbps back to Mbps.

Decimals and correctly grouped commas are supported. Negative rates are rejected.
Mbps and Gbps both measure data transfer rate in bits per second. The only change here is the SI prefix.
Mega means 10⁶ and giga means 10⁹, so one gigabit per second equals exactly 1,000 megabits per second.
The lowercase b means bits. A byte contains eight bits, so Mbps and MB/s are different units.
Mbps means megabits per second and Gbps means gigabits per second. Both describe a data transfer rate: how many bits can be transferred in one second. They are commonly used for internet connections, Ethernet links, network equipment, and other communication speeds.
The conversion is decimal because mega and giga are SI prefixes. Mega represents 10⁶ and giga represents 10⁹, so a gigabit contains 1,000 megabits. That gives the exact relationship 1 Gbps = 1,000 Mbps.
You may see binary prefixes such as mebi and gibi in computing, but those are different prefixes with different symbols. They do not change the Mbps-to-Gbps conversion on this page.
Example: 750 Mbps ÷ 1,000 = 0.75 Gbps.
Example: 2.5 Gbps × 1,000 = 2,500 Mbps.
Mbps uses a lowercase b, so it means megabits per second. MB/s uses an uppercase B, so it means megabytes per second. A byte contains eight bits.
To convert a bit rate to the corresponding byte rate, divide by 8. For example, 1 Gbps is 1,000 Mbps, which corresponds to 125 MB/s as a raw unit conversion. That does not guarantee a 125 MB/s application download speed because real transfers can include protocol overhead and other bottlenecks.
Likewise, Mbps cannot be converted directly to a storage amount such as MB or GB unless a time interval is also known. A rate tells you how fast data moves; storage units describe an amount of data.
Exactly 1,000 Mbps. Giga is 1,000 times mega, so 1 Gbps = 1,000 Mbps.
Divide 500 by 1,000. The result is 0.5 Gbps.
Multiply 2.5 by 1,000. The result is 2,500 Mbps.
No. Mbps and Gbps use decimal SI prefixes, so 1 Gbps equals 1,000 Mbps. Binary prefixes use different names and symbols, such as mebi and gibi.
No. Mbps means megabits per second, while MB/s means megabytes per second. Since one byte contains eight bits, 800 Mbps corresponds to 100 MB/s as a raw unit conversion.
Not without a time interval. Mbps is a rate, while GB is an amount of data. You need to know how long the transfer lasts before calculating a data amount.
No. It expresses the same transfer rate on a different numeric scale. For example, 1,000 Mbps and 1 Gbps describe the same rate.
The unit conversion gives the mathematical relationship between bits and bytes. Real application throughput can be lower because of protocol overhead, network conditions, server limits, device limits, or other bottlenecks.
