Okta Okta In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Sky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely overcast). In addition, in the SYNOP code there is an extra cloud cover indicator '9' indicating that the sky is totally obscured (i.e. hidden from view), usually due to dense fog or heavy snow. When used in weather charts, okta measurements are shown by
Theory of conjoint measurement magnitude of "A" per unit magnitude of "X". For example, "A" consists of masses and "X" consists of volumes, then "P" consists of densities measured as mass per unit of volume. In such cases, it would appear that one level of "A" and one level of "X" must be identified as a tentative unit prior to the application of conjoint measurement. If each level of "P" is the sum of a level of "A" and a level of "X", then "P" is the same quantity as "A" and"X". For example, "A" and "X" are lengths so hence must be "P".
