Usage notes

The letter k is not normally used in Catalan. Instead, Catalan orthography calls for using the qu digraph to represent the /k/ sound before an e or an i. Therefor, when the metric system was introduced into Catalan, the prefix kilo- was originally spelled quilo-. With the advent of k as a standard international abbreviation, usage of kilo- has become not only acceptable, but also more common than the traditional spelling. However, traditionalists still insist upon the use of quilo-.
