How many gigabits per second are in a megabit per second?

1 Mbps = 0.001 Gbps. To convert any amount, multiply by 0.001.

How do you convert megabits per second to gigabits per second?

Multiply the number of megabits per second by 0.001 to get gigabits per second. The formula is shown in the "How it's calculated" section above.

Where does the conversion factor come from?

It's a published international standard. Most are defined exactly by international agreement (e.g. 1 inch = 25.4 mm exactly, 1 lb = 0.45359237 kg exactly). Source citations are listed under the formula above.

How it's calculated

Convert megabits per second to gigabits per second— the formula

Megabits per second convert to gigabits per second by multiplying by the published conversion factor. The factor below is exact to the precision shown, sourced from the citation under the formula.

Gbps = Mbps × 0.001

Mbps = Gbps × 1000

IEC 80000-13: decimal SI prefixes for bit rates. 1 Kbps = 1000 bps, 1 Mbps = 10⁶ bps, 1 Gbps = 10⁹ bps.
