Effortlessly convert between KB, MB, GB, TB, and more. Essential for developers, system administrators, and anyone managing digital storage or file transfers.
In the digital world, data size is measured in bytes. As file sizes have grown from simple text documents to high-definition video, we use prefixes like Kilo, Mega, and Giga to represent larger amounts.
This is a common source of confusion. Operating systems (like Windows) typically calculate size using binary math, where 1 KB = 1024 Bytes. However, hard drive manufacturers often use decimal math, where 1 KB = 1000 Bytes. This is why a "500 GB" hard drive might only show as "465 GB" in Windows.
Our calculator uses the standard Binary (1024) system used by most operating systems and software.
Used for MP3 songs (3-5 MB) or photos (2-10 MB). 1 MB = 1,024 KB.
Used for HD movies (2-4 GB) or smartphone storage (64-256 GB). 1 GB = 1,024 MB.
Essential for IT Pros.
When configuring servers or coding file upload features, limits are often defined in Bytes. Use this tool to quickly convert "10 MB" into "10,485,760 Bytes" for your configuration files.
Precise byte calculations.
After Terabyte (TB) comes Petabyte (PB), then Exabyte (EB), Zettabyte (ZB), and Yottabyte (YB). Each is 1,024 times larger than the previous unit.
Manufacturers market 1TB as 1,000,000,000,000 bytes. However, computers read this in binary (1024 base), seeing it as approximately 931 GB. Formatting and OS files also take up some space.
