Ever wondered what a gigabyte (GB) really means when you're buying a new phone, choosing a mobile data plan, or saving a file? A gigabyte is one of the most common measurements of digital capacity.
In this guide, we'll break down exactly what a GB is, what you can fit into it, and why the storage space you buy isn't always what you see on your device.
A gigabyte (GB) is a unit of digital data storage, equal to one billion bytes. The plural form is gigabytes.
While a gigabyte (GB) is commercially defined as 1 billion bytes (109 bytes), operating systems like Windows often measure storage using a binary system.
In this system, the correct term is a gibibyte (GiB), which is equal to 230 or 1,073,741,824 bytes.
This ~7.4% difference is why a hard drive advertised as 500 GB might appear as only 465 GiB on your computer.
This discrepancy exists because manufacturers sell storage using the decimal system (powers of 10), while most operating systems measure it using the binary system (powers of 2).
A single gigabyte (1GB) offers a substantial amount of storage for everyday use.
For perspective, 1 GB can typically hold:
This capacity makes it a standard unit for measuring file sizes, app downloads, and mobile data plans.
In the early 1980s, a gigabyte of storage was an immense, costly amount of data, primarily found in multi-million dollar supercomputers.
The first gigabyte-capacity hard disk drive, IBM's 3380, was released in 1980. It weighed over 500 pounds and cost tens of thousands of dollars.
Today, gigabytes are a routine measure for devices that fit in our pockets, such as smartphones, SD cards, and USB drives, showcasing the exponential growth of data technology.
A megabyte (MB) is a unit of digital information equal to one million bytes (106 bytes).
The plural form is megabytes.
While a megabyte is commonly defined as one million bytes (1,000,000 bytes), especially for data storage devices like hard drives and USB sticks, computer operating systems often use a different measurement.
In this binary system, a "megabyte" actually refers to a mebibyte (MiB), which is 220 or 1,048,576 bytes.
This difference is why a 100 MB file on your computer takes up more than 100,000,000 bytes of space, and why a hard drive advertised as 500 GB might appear as approximately 465 GB in your operating system.
So, how big is a megabyte in practical terms?
To put its size into perspective, a single MB can hold a surprising amount of information depending on the file type. A megabyte is roughly equivalent to:
It's crucial not to confuse megabytes (MB) with megabits (Mb).
A megabyte (MB) is a unit of data size used for files.
A megabit (Mb) is a unit of data transfer speed, commonly used to measure internet connection speeds.
Since there are 8 bits in 1 byte, you need to divide the megabit value by 8 to find the maximum transfer speed in megabytes per second.
For example, a 100 Mbps (megabits per second) internet connection has a maximum theoretical download speed of 12.5 MBps (megabytes per second).
