Terabytes Gigabytes Petabytes and Exabyte: how big is all this?

You must have heard about Terabytes, Megabytes, Gigabytes, Petabytes and exabytes etc. But do you know what all these terms mean and what is the difference between Terabyte Gigabyte Petabyte and exabytes?

Terabyte, Gigabyte, Petabyte and Exabytes difference?

How many Gigabytes are there in 1 Terabytes? You must know all these things before buying a Hard Drive and Memory Card.


Here we are talking about Bytes. You must have heard about Bits at some time or the other. Let us first know the difference between Bytes and Bits.

1 BYTE has 8 BITS

A bit is a binary digit or small unit of a computerized data. A bit is very small, but it is also smaller than the size of the single character of an email.

These formulas convert 8 megabits into megabytes using 8 bits = 1 byte and also convert megabytes into megabits. Meaning 1 Byte has 8 Bits and 1 Bit has 0.125 Byte.


Because we know that the value of 1 Megabyte is 8 Megabit, so we can multiply Megabit by 8 and calculate the value of Megabyte.

Here we are giving some easy examples:

8 megabits = 1 megabyte (8 Mb = 1 MB)

1 megabit = 1/8 megabyte = 0.125 megabyte (1Mb = 1/8 MB = 0.125 M)

The easiest way to remember about the Size Difference between Megabits and Megabytes is that all you have to do is remember when its Units are equal (meaning when you are comparing Mb to Mb, or Mb to Mb). Is, then the number of megabit (Mb) will be larger (since 1 Byte has 8 Bits).

The easiest way to do megabit and megabyte conversion is to use Google. For example, if you search 1000 megabits to megabytes in Google, then you will get the answer without calculating it. In the same way, you can convert more different numbers using Google.

NOTE: Although 1 megabyte contains 1 million (10 lakh) bytes, this conversion is only in “million to million” as both are “megas”. So this means that we can use 8 as the conversion number instead of 8 Million.

Terabytes, Gigabytes, Petabytes and Exabytes: Which of the following is the largest?

You must first know who is the largest and the youngest of all these terms. We understand it in easy language below.

 An exabytes (EB) is larger than a petabyte.

A petabyte (PB) is larger than a terabyte ..

A terabyte (TB) is larger than a gigabyte ..

A gigabyte (GB) is larger than a megabyte ..

A megabyte (MB) is larger than a kilobyte.

A kilobyte (KB) is larger than a byte…

How many Gigabytes (GB) does a Terabyte (TB) contain?

There are 1024 GB in 1 TB.

1 TB = 1,024 GB = 1,048,576 MB = 1,073,741,824 KB = 1,099,511,627,776 B

If we look at it from the other side ..

A TB is 1024 times larger than a GB. To convert TB to GB, take the number of TB and multiply it by 1024, which will remove the number of GB. And to convert GB to TB, take the number of GB and divide it by 1024.

How many megabytes (MB) does a Gigabyte (GB) contain?

1 GB contains 1024 MB ..

1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 B

A GB is 1024 times larger than an MB. To convert GB to MB, take the number of GB and multiply it by 1024, which will remove the number of MB. And to convert MB to GB, take the number of MB and divide it by 1024.

2. Watching an HD Movie on Netflix can take up to 4 GB of data. 4K version may take close to 20 GB.

3. Most of the smartphones have 64 GB or 128 GB of storage.

We hope you have come to know about Terabyte Gigabyte Petabyte difference.

How big is an exabytes (EB)?

Talking about an Exabytes (EB) can be a bit crazy because it is so big. But some situation comes when the world also needs so much data.

However, an Exabytes (EB) is large enough to tell people about it. To store just 1 Exabyte (EB), 763 billion Floppy disks will be required or 1.5 billion CD ROM disks. Can you imagine how big it can be?

Here are some points about how big an Exabyte (EB) is:

 In 2010, the traffic of the Internet was 21 EB per month and after 7 years it became 122 EB which was almost 6 times more than in 2010.

2. 11 Million Movies can be stored in 4K Format in 1 EB storage device.

3. The entire Library of Congress can be stored more than 3000 times in 1 EB Storage.
