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
Unit of measurement is just mathematically the same thing, multiply "Z" by unity, the product is still "Z": For example, you have an expression for a physical value "Z" involving the unit "feet per second" (formula_9) and you want it in terms of the unit "miles per hour" (formula_10): Or as an example using the metric system, you have a value of fuel economy in the unit "litres per 100 kilometres" and you want it in terms of the unit "microlitres per metre": One example of the importance of agreed units is the failure of the NASA Mars Climate Orbiter, which was accidentally
