"Oka" can refer to different concepts depending on context, but in the context of mass, it is a unit of measurement traditionally used in Turkey and some other parts of the Middle East. One oka is approximately equal to 1.28 kilograms (about 2.8 pounds). It is not a commonly used unit in modern scientific or commercial contexts, as metric units like kilograms and grams are standardized in most parts of the world.
