Megabits to Gigabytes conversion

Note: Above conversion to GB is base 10 decimal unit. If you want to use base 2 (binary unit) use Megabits to Gibibytes (Mb to GiB) (which results to 0.0001164153218269 GiB). See the difference between decimal (Metric) and binary prefixes

How to convert megabits to gigabytes?

To convert Megabits (Mb) to Gigabytes (GB), you need to understand both the decimal (base 10) and binary (base 2) systems.

Base 10 (Decimal System)

In the base 10 system:

  • 1 Megabit (Mb) = 1,000,000 bits
  • 1 Byte = 8 bits
  • 1 Megabyte (MB) = 1,000,000 Bytes
  • 1 Gigabyte (GB) = 1,000,000,000 Bytes

Steps for conversion:

  1. Convert Megabits to bits: 1 Mb = 1,000,000 bits
  2. Convert bits to Bytes: 1,000,000 bits ÷ 8 = 125,000 Bytes
  3. Convert Bytes to Gigabytes: 125,000 Bytes ÷ 1,000,000,000 = 0.000125 GB

So, in base 10, 1 Megabit (Mb) is 0.000125 Gigabytes (GB).

Base 2 (Binary System)

In the base 2 system:

  • 1 Megabit (Mb) = 1,048,576 bits (since 1 Megabit = 2^20 bits)
  • 1 Byte = 8 bits
  • 1 Megabyte (MB) = 1,048,576 Bytes (since 1 Megabyte = 2^20 Bytes)
  • 1 Gibibyte (GiB) = 1,073,741,824 Bytes (since 1 Gibibyte = 2^30 Bytes)

Steps for conversion:

  1. Convert Megabits to bits: 1 Mb = 1,048,576 bits
  2. Convert bits to Bytes: 1,048,576 bits ÷ 8 = 131,072 Bytes
  3. Convert Bytes to Gibibytes: 131,072 Bytes ÷ 1,073,741,824 = 0.0001220703125 GiB

So, in base 2, 1 Megabit (Mb) is approximately 0.0001220703125 Gibibytes (GiB).

Real-World Examples

  1. Internet Speed: Internet service providers often advertise speeds in Megabits per second (Mbps). For example, a 100 Mbps internet connection means that 100 Megabits of data can be transferred every second.

  2. File Downloads: If a file is 800 Megabits (Mb) and you want to know its size in Gigabytes (GB):

    • Base 10: 800 Mb = 800 × 0.000125 = 0.1 GB
    • Base 2: 800 Mb = 800 × 0.0001220703125 ≈ 0.09765625 GiB

  3. Streaming Videos: A high-definition (HD) video stream might use 5 Megabits per second (Mbps). Watching it for one hour (3600 seconds) would use:

    • Base 10: 5 Mbps × 3600 s = 18,000 Megabits = 18,000 × 0.000125 = 2.25 GB
    • Base 2: 5 Mbps × 3600 s = 18,000 Megabits = 18,000 × 0.0001220703125 ≈ 2.197265625 GiB

These examples illustrate the practical difference between base 10 and base 2 conversions, which can be significant depending on the context and the amount of data being measured.

See below section for step by step unit conversion with formulas and explanations. Please refer to the table below for a list of all the Gigabytes to other unit conversions.

What is megabits?

Megabits (Mb) is a unit of measurement used to express digital data, particularly in the context of internet connectivity and digital communication.

In simple terms, a megabit is a large amount of binary information that can be transmitted or stored digitally. Here's how it breaks down:

  • 1 bit = 0 or 1 (a single binary digit)
  • 1 kilobit (kb) = 1,000 bits
  • 1 megabit (Mb) = 1,000 kilobits (kb) = 1,000,000 bits

To put it in perspective, here are some examples of data sizes:

  • A typical image on your phone might be around 2-5 megabits ( Mb)
  • An hour-long movie at low quality could be around 10-20 gigabits (Gb), which is equivalent to tens of thousands of megabits
  • A full-length, high-definition TV show can take up hundreds of gigabytes (GB) or millions of megabits

In internet connectivity, megabits are often used to describe the maximum data transfer rate that a network connection can handle. For example:

  • DSL internet might have speeds ranging from 1-10 megabits per second (Mbps)
  • Cable internet may offer speeds up to 100 Mbps or more
  • Fiber-optic connections can reach speeds of 1 gigabit per second (Gbps), which is equivalent to 1,000 Mbps

In summary, megabits are a measure of digital data and are often used in the context of internet connectivity, storage capacity, and digital communication.

What is a Gigabyte?

Gigabyte, GBGB, is a unit of digital information. Giga is used as a unit prefix in metrics system. It represent a numerical value 10910^9 or 1,000,000,0001,000,000,000. List of SI prefix can be found on Wikipidia.

There are two common ways unit of information is represented. One is in decimal (base 10) form and the other is in power of 2 (binary). GigabyteGigabyte is referring to the base 10 format, unlike GigibyteGigibyte which is referring to base 2 format.

1 Gigabyte=>1 GB (shorthandform)1\,Gigabyte => 1\, GB\,(shorthand form)
