quilo-

See also: quilo

Catalan

Etymology 1

Borrowed from French kilo-, from Ancient Greek χίλιοι (khílioi, “thousand”).

Alternative forms

• kilo-

Prefix

quilo-

1. kilo- (SI prefix expressing 10³ of the base unit)

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-.
