MiB to KiB Converter
Convert mebibytes to kibibytes — exactly 1,024 kibibytes to the mebibyte. Results update as you type; exact factors shown.
One mebibyte (2²⁰) is 1,024 kibibyte (2¹⁰) — see the exact factor, not a rounded rule of thumb.
How the mib to kib converter works
Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.

FAQFrequently asked questions about data conversion
How many KiB in a MiB?
Exactly 1,024.
What is 1 MiB in bytes?
1,048,576.
Where does this matter?
Buffer sizes, memory allocation and anything counting in powers of two.
What is a floppy disk?
The 1.44 MB floppy was really 1,440 KiB — neither a true megabyte nor a true mebibyte, which is its own small scandal.
What is 1,024 MiB?
One gibibyte.
