About these units

Storage sizes come in two systems. Decimal (SI) units step by 1,000: 1 KB = 1,000 bytes, 1 MB = 1,000 KB and 1 GB = 1,000 MB. Binary (IEC) units step by 1,024: 1 KiB = 1,024 bytes and 1 MiB = 1,024 KiB. Drive makers and most specifications use decimal units, while Windows and many programs count in binary but label the result KB, MB or GB, which is why a 1 TB drive shows up as about 931 GB. One byte is 8 bits.

FAQ

› How do I convert MiB to MB?

1 MiB = 1.048576 MB. To convert, multiply the value by 1.048576: 2 MiB = 2.097152 MB.

› What is 1 MB in MiB?

1 MB = 0.9536743164 MiB. The reverse formula is MiB = MB ÷ 1.048576.

› Is 1 MB 1,000 KB or 1,024 KB?

In SI units 1 MB is 1,000 KB. The 1,024-based unit has its own name, the mebibyte (MiB). Some software still writes MB for 1,024 KB, so check which convention a number uses.

› Why does a new drive show less space than advertised?

The box uses decimal gigabytes (10⁹ bytes) while the operating system reports binary gibibytes (2³⁰ bytes) labeled GB. A 500 GB drive is about 465.66 GiB; no space is missing.
