In this article, you’ll learn to answer questions like knowing how many KB are in a GB – you can also find it written as “How many kilobytes in a gigabyte”. We’ll also dive into other file sizes explanations and their conversions.
Understanding file sizes is not always that simple. There are a bunch of different units regarding computer storage space and that can lead to a lot of confusion.
The “kilo“, “mega“, “giga” and “tera” prefixes that we use before a are similar to their use in any other of measurement, like meters or watts. They were established long before the computer era, along with many more units used in the metric system too, such as “centi”, “milli”, “micro”, and others. They were all based on powers of 10.
Roughly, this is how the conversions are done:
 1 B = 1 byte;
 1 kB = 1000 bytes;
 1 MB = 1000 kB or 1 000 000 000 bytes;
 1 GB = 1000 MB or 1 000 000 000 bytes;
 1 TB = 1000 GB or 1 000 000 000 000 bytes.
However, to make things a little bit more confusing, in the tech world, a factor of 1,000 is actually 1,024, 1,000,000 is 1,048,576 and 1,000,000 is in fact 1,073,741,824. That happens because computer components are built around binary numbers, they don’t make use of decimals.
Computers do use powers of 2 instead of powers of 10. When talking about computer memory, considering the way it is conceived, it became common in the computer world to use those prefixes to refer to the nearest multiple of 1024.
This is because semiconductor memory doubles in size for each one of the address lanes added to an integrated circuit package. As a result, it favors counts that are powers of two.
Historical review
In today’s world, terms like bytes, kilobytes, or even megabytes are gradually disappearing from the tech vocabulary of the younger generations as is increasing.
It’s not common anymore to find a (or even SSDs) with less than some hundreds of gigabytes of . Even most smartphones are now offering at least 64 or 128GB so they’re able to allocate .
But, if we go back to the 90s, it was a very common practice to use floppy disks, the thumb drives of the era. It was the preferred back then. Those floppy disks, also known as “diskettes” used to have a of up to just 1440 KB (roughly 1,44 MB).
It was also during the 90s that most computers started to be equipped with drives, with just a couple of megabytes of at first.
Focusing on RAM (Random Access Memory), most computers from the late 80s and early 90s were equipped with just 512 KB or 640 KB. Only during the late 90s that we started to see “bigger” capacities of 8 MB, 16 MB, 32 MB, and 64 MB. Higher than that was only reserved for servers and higherend machines of the era, even if it’s hard to imagine it now.
How many kB in a GB will you find (How many kilobytes in a gigabyte) and other file sizes explained (Bytes, kB, MB, GB, TB)
Before we start with some practical examples to get things clearer in your mind, let’s answer one of the most common questions about .
How many Kilobytes are there in a Gigabyte?
Well, there are 1,048,576 Kilobytes in a Gigabyte.
What is a byte?
A byte is the smallest unit of memory in the computer architecture and it is represented by a “B”. It consists of 8bits (a series of eight zeros and ones), which is the number of bits used to encode one single text character in the computer world.
One byte can be used to represent 256 different values. The byte was originally created to store and symbolize a single text character since 256 different values were enough to represent all lowercase and uppercase letters, numbers, and symbols in western alphabets.
As a byte contains so little information, the measuring of storage capacities of computer hardware is usually given in megabytes, and more commonly in gigabytes or even in terabytes.
How many bytes in a kilobyte?
Roughly you can say that there are 1 000 bytes in a KB, but that is not precise as we have pointed above.
Stating the facts with precision, the kilobyte is traditionally used to refer to 1024 bytes. So 1 KB equals 1024 bytes.
How many bytes in a megabyte?
What is a megabyte? The megabyte or MB is commonly used to measure 1024^{2} bytes. Like the previous examples, 1 MB equals 1024 x 1024 which is 1,048,576 bytes.
How many bytes in a gigabyte?
What is a gigabyte? One gigabyte is roughly one billion bytes. To be precise, 1 GB equals 1024³, or 1024 x 1024 x 1024, which is 1,073,741,824 bytes.
How many bytes in a terabyte?
How big is a terabyte? The prefix tera represents the fourth power of 1000. 1 TB equals 1024^{4} bytes, or 1024 x 1024 x 1024 x 1024 which is 1,099,511,627,776 bytes.
What comes after a terabyte?
What is bigger than a ? “Tera” is the fourth power of 1000 or 10004 as stated above. The prefix after tera when considering tech, is 10245, or “peta“. So, after a , comes the as a .
Wrap Up
Computer storage units can lead to a lot of confusion. Especially because computer components don’t make use of decimals, they’re built around binary numbers instead.
We hope that by reading this article you get things clearer on your mind and understand easily how you can convert Gb to Mb, Gb to Tb, Tb to Gb, Mb to Tb, etc.
