file sizes

All computers and other digital computer storage devices have file sizes in which their data and information and software and other memory-consuming things are stored that’s why Understanding file sizes | Bytes, KB, MB, GB, TB, PB, EB, ZB, YB is important.

In the field of computers, these phrases are typically used to refer to system memory, disc space, and data storage space. Megabytes (MB) were common units used to measure computer storage in past. We used to refer to hard disc space using the term Megabytes years ago.

But the most popular phrase today for describing a hard drive’s size and even smartphones is ” gigabyte” and “terabyte.” Terabyte had become a well-known term in the not-too-distant future. A kilobyte (KB) is 1,024 bytes, not the 1,000 bytes that one may believe because computers use binary (base two) math instead of a decimal (base ten) system.

One megabyte is not one million bytes, but rather 1,024 kilobytes, or 1,048,576 (1024×1024) bytes. To know in detail about these file sizes read the below given so you can easily understand these. SO LETS START!




Before understanding the all file sizes you need to should know the term bit so what is a bit? The smallest unit of data that a computer can process and store is a bit (binary digit). Then now comes the file sizes which are described below:

File sizes are typically measured in bytes, with larger files having a higher number of bytes. The size of a file is determined by the amount of data it contains.

Here are some common units of measurement for file sizes:

  • Bytes (B): A byte is the smallest unit of measurement for file size. It is equal to 8 bits.

  • Kilobytes (KB): A kilobyte is equal to 1,024 bytes. It is often used to measure the size of small files such as text documents or images.

  • Megabytes (MB): A megabyte is equal to 1,024 kilobytes or 1,048,576 bytes. It is often used to measure the size of larger files such as videos or software programs.

  • Gigabytes (GB): A gigabyte is equal to 1,024 megabytes or 1,073,741,824 bytes. It is often used to measure the size of very large files or collections of files such as music libraries or photo albums.

It’s important to keep file sizes in mind when designing and maintaining a website. Large file sizes can slow down the loading times of a website, which can be frustrating for users. It’s generally recommended to keep file sizes as small as possible without sacrificing quality.

There are various tools and techniques that can be used to optimize file sizes, such as compressing images or using streamlined code. By optimizing file sizes, you can help improve the loading times and overall performance of your website.


A byte is an amount of data used in computer systems and there are 8 bits in a byte. Computers utilize bytes to represent characters like letters, numbers, and typographic symbols. A byte is the most frequent kind of storage in computers. Hard drives, DVDs, CDs, and USB sticks all have capacities that are expressed in terms of bytes rather than bits.


Because the humble computer bit can only describe one of two things only: on or off, 1 or 0, true or false, and so on. Dealing with higher-level units is much simpler than constantly designating things in bits. So, instead of using bits as the fundamental unit of information in computers, it uses bytes. As a result, there are now many byte sizes like kilobytes, megabytes, gigabytes, etc.

Binary data is stored in numerous units called kilobytes (KB) and KB to MB is 0.001 MB. the most used unit for gauging the size of small files is the kilobyte.  In computer science, a kilobyte is frequently defined as 1,024 (210) bytes, even though “kilo” normally refers to 1,000. Depending on the context, it may also be used to refer to 1,000 bytes, and kb to GB is 1e-6 GB.


A plain text document, for instance, might have a file size of 10 KB and contain 10 KB of data. Small website visuals often range in size from 5 KB to 100 KB. Modern file systems like NTFS (Windows) and HFS+ (Mac) have a cluster size of 4 KB, even if some files only have 4 KB or less of data.

This metric is frequently used to define disc storage and memory capacity. The International System of Units (SI) converts a kilobyte to 8,000 bits, making it a simple way to indicate a high number of bits (or 8096 bits for computer programming and IT applications).

1 KB Kilobyte =

1,024 Bytes



MB meaning- MB means a data measuring unit used for digital computer or media storage which stands for the megabyte if we convert MB to KB  then ( 1MB = 1024KB ). A megabyte is one of the units that make up the SI or International System of Units. However, the value of a megabyte varies depending on the application.

Although it is used in other fields, this unit essentially measures data volume in the computing industry. Megabytes are still used in a variety of measuring contexts, such as memory, software, and digitally supported computer and media data, depending on the file format, drive capabilities, and compression. MB counts text files, bitmap images, media files, compressed or uncompressed audio, and video files.

1 MB Megabyte =


1,048,576 Bytes



The letter GB stands for gigabytes and there are 1024 MB in a GB. For computers, tablets, smartphones, game consoles, and other digital computing devices, a gigabyte is a unit of measurement for data storage. The gigabyte is one of the most well-known units of measurement. In actuality, the majority of people own smartphones and are aware of the lengthier GB acronyms.

People frequently come across it while selecting the data volume of a new mobile phone plan, USB stick, or memory card for a smartphone or any other digital storage device. To denote the monthly data amount included in a mobile phone contract, Gigabyte is also used in mobile phone rates. Typically, gigabytes are used to measure memory, data transmission speed, and storage capacity (RAM).

One Terabyte (TB) is a sizable amount of digital data. A high amount of data storage space, commonly applied to hard disc drives, is known as a terabyte (TB). Computer systems require hard disc drives because they hold the operating system, applications, files, and data required to function. In terms of measuring data, a terabyte is still a monster no matter how you look at it.

A terabyte may store as much data as 1,498 CDs or almost a million floppy discs. It wasn’t until 2007 that the first 1 TB external hard disc was produced. It can be either 1,000 gigabytes (GB) or 1,024 GB, depending on the type of storage being evaluated; disc storage is typically measured as the first, while CPU storage is the second.

Any computer enthusiast who wants a must large storage can use terabytes, Games, photographs, films, and software are examples of file types that contain significant amounts of data.

A petabyte is a very large digital data unit that is equivalent to 1,000 terabytes. According to some calculations, a petabyte is equal to 500 billion pages of conventional printed text or 20 million tall filing cabinets. Traditional data backups are not suitable for petabytes because they require a system-wide scan each time a data backup or archiving activity takes place.

Although conventional network-attached storage (NAS) is expandable and capable of handling petabytes of data, it may require a lot of resources to navigate the system’s ordered storage index. The capacity to gather and analyze enormous volumes of data is crucial for many of today’s top firms. Corporations, who rely on such vast volumes of data, are understandably concerned about storage so petabyte is a great choice.

An extremely huge digital data unit in Exabyte. In today’s age, several exabytes of data are produced each month on a global scale. Google claims to have a data storage capacity of several exabytes. Measurement of our commercially accessible hardware, such as the external storage hard drives, we might utilize daily, an exabyte is nevertheless limited to global data volumes and storage quantities in data centers.

Because it is so big, the exabyte unit of memory measurement is not utilized to gauge storage device capacity. Even the largest cloud storage facilities measure their data storage capacity in Petabytes, which is a small fraction of an EB. Exabytes measure the volume of data spread across several networks of data storage or the volume of data being transported over the Internet for a predetermined period.

The enormously high unit of measurement for digital storage is the zettabyte. Simply said, storing one zettabyte of data would require one billion, one terabyte hard discs. Only massive aggregate volumes of data are measured using the zettabyte unit of measurement due to its size. Even the total amount of data in existence is only thought to be a few zettabytes.

Nothing can be used to compare a Zettabyte other than to point out how many ones and zeroes would be required to fill it. One zettabyte contains one billion TBs, or one sextillion bytes, hence one zettabyte of data would need one billion one-terabyte hard drives to store it.

Zettabytes are typically used to measure extremely large amounts of knowledge, and the total amount of knowledge on earth is only a few zettabytes.

About 1,000 Zettabytes make a Yottabyte. A Yottabyte file may be downloaded via the Internet using high-speed broadband in about 11 trillion years. The World Wide Web, which almost occupies a Yottabyte, can be used as a comparison. One septillion bytes or one trillion bytes also make up a yottabyte or one billion trillion bytes.

People can contemplate a very large amount of it. Because the total amount of information on the planet may be represented by just a few zettabytes, there is no practical use for such a large measuring unit. Remember that nothing is currently measured in yottabytes; it is merely a theoretical quantity ready to be put to use in the supercomputing world of the future.

I hope that Understanding file sizes | Bytes, KB, MB, GB, TB, PB, EB, ZB, YB was interesting for you. In today’s age, there will be no one who does not use any of the KB, MB, GB, or TB, for their computer, laptop, smartphone, tabs, digital camera, etc. However, PB, EB, and ZB are only used by people who require high storage. Only Yottabyte usage is still proceeding.

The most commonly used today is the gigabyte and recently terabytes have been introduced to smartphones but were present in computers a few years ago. Understanding these file sizes and their usage will help you to choose between them depending on what amount of storage you require for your digital storage device. BEST OF LUCK!
