About Data Size Units (Binary vs. Decimal)
Digital data size is measured in units like Bytes, Kilobytes, Megabytes, etc. However, there's often confusion due to two different systems:
- Binary (Base-1024): Used traditionally by operating systems (like Windows) to measure memory and file sizes. Prefixes are Kibibyte (KiB), Mebibyte (MiB), Gibibyte (GiB), Tebibyte (TiB). Here, 1 KiB = 1024 Bytes, 1 MiB = 1024 KiB, and so on.
- Decimal (Base-1000): Used by hard drive manufacturers, for network speeds, and increasingly in some operating systems (like macOS). Prefixes are Kilobyte (KB), Megabyte (MB), Gigabyte (GB), Terabyte (TB). Here, 1 KB = 1000 Bytes, 1 MB = 1000 KB, etc.
This difference explains why a 1 TB hard drive might appear as around 931 GiB in Windows. This calculator lets you choose the base for accurate conversions depending on your context.
