Gigabit [Gb] to Megabit [Mb] Converter

Quick Reference

1 Gigabit (Gb) = 1024 Megabit (Mb)

1 Megabit (Mb) = 0.0009765625 Gigabit (Gb)

How to Convert Gigabit to Megabit

1 Gb = 1024 Mb
1 Mb = 0.0009765625 Gb

To convert Gigabit to Megabit, multiply the value by 1024. To convert Megabit back to Gigabit, divide by 1024.

Example: convert 10 Gb to Mb:
10 Gb = 10 x 1024 = 10240 Mb

↔ Convert Megabit to Gigabit

Gigabit

Definition: A gigabit (Gb) is a unit of data storage equal to 1,000,000,000 bits. It is a multiple of the bit and is commonly used to measure high-speed data transfer rates.

History/origin: Similar to the megabit, the gigabit uses the SI prefix 'giga' to denote one billion. Its usage grew with the increasing capacity and speed of digital communication technologies.

Current use: Gigabits are used to quantify very high data transfer rates, such as the speeds of Ethernet connections (e.g., Gigabit Ethernet) or fiber optic internet connections.

Megabit

Definition: A megabit (Mb) is a unit of data storage equal to 1,000,000 bits. It's a multiple of the bit, which is the fundamental unit of information in computing and digital communications.

History/origin: The megabit is based on the bit and uses the SI prefix 'mega' to denote one million. The concept of bits arose with the development of digital computers and information theory in the mid-20th century.

Current use: Megabits are commonly used to measure data transfer rates, such as network speeds or internet connection speeds. For example, internet service providers often advertise speeds in megabits per second (Mbps).
