Kilobytes to Kibibytes Converter
Convert decimal kilobytes to binary kibibytes and back.
Distinguish kB from KiB
Kilobytes are decimal units of 1,000 bytes, while kibibytes are binary units of 1,024 bytes. The numeric difference is small at this scale but still relevant in file limits, embedded systems, and technical documentation. This converter preserves the proper capitalization and definitions.
The default 1 kB converts to 0.976563 KiB. Reversing direction shows that 1 KiB equals exactly 1.024 kB. The quick table makes the accumulating difference visible and avoids confusing bytes with similarly abbreviated kilobits.
Local byte-unit conversion
The calculation runs in your browser and does not read or upload a file. It converts stated capacities rather than actual allocated disk usage. Headers, block sizes, encoding, compression, and filesystem metadata can make a stored object occupy a different number of bytes.
