用法筆記
Kilo- as a prefix is always attached directly to the unit name (no space or hyphen). It operates at very high frequency with metric units: kilometer, kilogram, kilowatt, kilocalorie, and kiloliter are the most common. Do not confuse the prefix (kilo-) with the standalone noun 'kilo,' which is an abbreviation for kilogram only.

文法句型
kilo- + [technical noun]
用法筆記
In computing, a kilobyte (KB) traditionally equals 1,024 bytes (2^10), not exactly 1,000 bytes, because computers use binary arithmetic. The same binary interpretation applies to kilobytes of memory. For disk storage, manufacturers often use the decimal 1,000 definition. This dual usage can cause confusion; the term 'kibibyte' (KiB) was introduced to mean exactly 1,024 bytes, but it is not yet widely used outside technical contexts.
