a unit of proportion equal to 1/8, used in meteorology to record the fraction of the sky covered by clouds. For example, if half the sky is cloud-covered, the coverage is reported to be 4 oktas. The name of the unit comes from the Greek numeral 8, okto. It was coined to provide a word meaning "eighth" in all languages.
