What is KB, MB, GB and Why are They Important? [The 2022 Ultimate Guide]

Understanding file size such as GB, MB, and KB is a great way to avoid exceeding the limited storage space on your device. It can significantly help prevent sending too large files via email, social media platforms, or share to other devices. Moreover, you can think of a way to minimize the large files to make them smaller. In this article, you will learn how file size with GB, MB, KB, which file size takes too much space on the computer system. Also, you can find some methods to compress GB files to make smaller file sizes without losing quality.

Part 1: Introductions to the File Size: Bytes, KB, MB, and GB

The memory compromises many decisive circuits that can be either off or on and are represented by 0 or 1. Counting higher than 1, you need to use bits and bytes to form larger numbers, resulting in KiloBytes (KB) or MegaBytes (MB). For specific measurements for type of bytes, read further to know the difference of Bytes.

What is Byte?

A byte is a unit of data that is eight bits long (BInary digiTS), and computer systems use this unit to represent a character like a number, letter, or other symbols such as $. It is the smallest unit of information that a computer can process. A byte can also hold a string needed in some large units of the application process, including KB, MB, and GB. The best example is the stream of bits composing the machine code of a computer program.

Note

The measurement system of a byte is different for every country. However, the most accepted measure for byte is eight bits.

What is KB?

A KB or Kilobyte is a smaller unit of memory measurement but more extensive than a byte. A Kilobyte is composed of 1024 bytes, and it is synonymously used as kibibytes which are 1,024 bytes. A simple text document is an excellent example as it often uses 10KB and only takes small storage space.

What is MB?

A Megabyte is abbreviated as MB contains 1,000,000 bytes, and is equal to 1,024 kilobytes. Mainly, megabytes are used to measure large files. You can compare it to a JPEG image with high resolution that can range from 1 to 5 MB in size, or compressed audio with a 3-minute duration can be roughly 3MB in size.

What is GB?

A GB(Gigabyte) is measured with 1,024 Megabytes and 1,000,000,000 bytes. It is also abbreviated as gigs, and what's more, it is used synonymously with gibibytes composed of exactly 1,073,741,824 bytes. Gigabyte is used to measure a device's storage capacity like a standard DVD drive which holds 4.7Gigabytes of data.

Part 2: Which is Bigger? KB, MB, or GB?

1. Comparison between KB, MB, and GB

From the explanation above about the memory unit measurements, it is obvious to know that Gigabytes are bigger than Megabytes and Kilobytes. However, you can precisely see the difference in these unit measurements in the table below:

1 Kilobyte (KB) =1024 bytes
1 Megabyte (MB) =1024 KB/ 1,048,576 bytes
1 Gigabyte (GB) =1024 MB/ 1,073,741,824 bytes

2. Difference between the KB, MB, and GB photos and videos

Even when you learn about the importance of memory measurement, the file size should be considered when you download or store files. You also need to make sure that the greater the file size is, the more it takes storage space. For photo quality, it is well recommended to keep files size under 100KB. For video, it is good to consider the duration, bitrate, and resolution of the video. For example, if you have a 2.5-hour long video with 1080p resolution, you can roughly store it to 1GB.

If you have files that are way too large for your storage space, you can use software that will help to reduce the file size without losing too much quality. But which is the best tool to compress GB video files to MB? Please keep reading!

How to compress video files with MB on AnyRec Video Converter:

Step 1Download the software on your device and launch it. Locate the Toolbar option on the top part of the pane to start video compressing. Among the tool options, select the Video Compressor button. Click the Plus button to select the video file you want to reduce from 1GB to 10MB.

Choose The Video Compressor

Step 2After it is uploaded, the video setting will appear with a default reduced file size but you can move the Size Slider to choose the desired file size. Change other settings like resolution and bitrate by clicking from the drop-down menus. Click the Preview button to watch the first 10 seconds of the video file so you can adjust if the quality is too low.

Compress Videos To Desired Size

Step 3Browse on the Save To option to choose the destination folder of the compressed file. After that, click the Compress button on the lower part of the pane to start compressing MP4 videos. The compression process may take some time, depending on the length of the video file. The selected folder will appear with the compressed GB video file after it finishes.

Save Compressed Videos

Part 4: FAQs about KB, MB, and GB File Size

Conclusion

The unit measurements are KB, MB, and GB that are formed with millions of bits or Binary Digits. These measurements are bound to hold essential data like video, audio, document, and more. Having a large file is possible to reduce the file size when you use a video compressor like AnyRec Video Converter. Share this knowledge to your friends now!
