Every computer owner has a questions about data storage metrics like what is terabytes, gigabytes, petabytes, megabytes etc.
We know these terms commonly, but we might not know how many gigabytes are in a terabyte? What does one terabyte stands for? It’s good to know the answer of these questions before you buy any storage media like external hard drives, internal hard drive, solid state drive, USB drive, memory card and so on.
Terabytes, Gigabytes, & Petabytes
As a matter of fact, these all are measuring units and are easily convertible from one to another, and are simple concepts allowing you to understand the difference.
Terabytes, Gigabytes, and Petabytes
The basics involves the bigger, smaller, abbreviations, and numbers. All of these computer technology storage units of measurements has one base which is a byte made up of 8 bits and it’s the amount of storage to store one character of text.
- An exabyte (EB) is larger than a…
- petabyte (PB), which is larger than a…
- terabyte (TB), which is larger than a…
- gigabyte (GB), which is larger than a…
- megabyte (MB), which is larger than a…
- kilobyte (KB), which is larger than a…
- byte (B)
We generally don’t talk about bits or zettabytes and yottabytes. Though these are not far but right now it’s not impressive to talk about these. Every level is the multiple of 1,024 which takes from one unit to another. You will get idea from the table given below.
There are some online resources which tells that each new level is 1,000 times greater than smaller while negating the 1,024. Practically it’s true but the real math is with 1,024.
Let’s do some practical stuff to know more about the storage capacities.
How Many Gigabytes (GB) in a Terabyte (TB)?
There are 1,024 GB in 1 TB.
1 TB = 1,024 GB = 1,048,576 MB = 1,073,741,824 KB = 1,099,511,627,776 B
Let me explain it…
A TB is 1,024 times bigger than a regular GB. You can know GBs in a TB by simply multiplying the number of TBs with 1,024 and to get TBs from GBs you can divide 1,024 by the number of TBs.
How Many Megabytes (MB) in a Gigabyte (GB)?
There are 1,024 MB in 1 GB
1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 B
A GB is 1,024 times bigger than a regular MB. You can know MBs in a GB by simply multiplying the number of GBs with 1,024 and to get GBs from MBs you can divide 1,024 by the number of GBs.
How Big Is a Terabyte?
Terabyte is the commonly used unit for hard drive size and you might still be using one in your computer.
A single TB is a lot of space. It would take 728,177 floppy disks or 1,498 CD-ROM discs to store just 1 TB worth of information.
Today in 2018 there are several hard drives available from 1 to 3 TB range. Many ISPs has monthly 1TB data usage. The Hubble Space Telescope generates around 10 TB of data every year. You can store 130,000 digital photos in 1TB space. Watson the famous supercomputer by IBM has 16TB of RAM. You should also know GB to TB that 1 TB has more than one trillion bytes.
How Big Is a Petabyte?
The petabyte (PB) is much larger storage space which is getting popular now a days. A single PB is capable of storing data similar to 745 million floppy disks or 1.5 million CD-ROM discs. Though not a good way to collect a petabyte but it’s sill amazing.
The movie Avatar needed 1PB to render the graphics. The human brand can store around 2.5PB of memory data. 1PB can hold 3.4 years of 24/7 Full HD video recording. In 2016 wayback machine was using 15PB of data. 1 PB allows you to store 4,000 digital photos per day for your whole life. A single PB contains 1,024 TB which is 1 quadrillion bytes.
How Big Is an Exabyte?
Exabyte is another higher number of data storage which can store 763 billion floppy disks or 1.5 billion CD-ROM discs.
In 2010 internet was handling 21 EB per month and 4.5 times higher in next six years. You can store 11 million 4k movies in 1 EB. A single EB can hold 3,000 times the entire Library of Congress. A gram fo DNA can hold 490 EB in a minute. A single EB hold around 1,024 PB which is 1 quadrillion bytes.
How Big Is a Gigabyte?
A gigabytes is the most commonly used storage metric around. We can commonly see movies in GB, memory cards, smartphone data plans and so on.
A single GB is equivalent to 700 floppy disks and a single CD. A single GB can store 300 MP3 songs. Single netflix HD movie can take 4GB space and the 4K version in 20GB. A DVD movie disc hold about 9.4 GB. Most smartphones store 64GB or 128 GB of data. You can subscribe wireless network on your mobile in 5GB, 10GB or more sizes in a month.
So now you have good idea of MB to GB conversions.
The Byte Table
Here it all is together, which helps to illustrate just how big some of those big numbers get!
The Yottabyte is not the end, there’s a bronotbyte which is 1,024 times Yottabyte and 1,024 times of brontobyte is geopbyte and the digits cannot be written here.
