Hvat (Serbian: Хват) is a historical unit of length that was common in Croatia and Serbia analogous to fathom. The measurement system based on the hvat is called hvatski sistem [1] (literally "hvat system"). 1 hvat equals: 6 × stopa [1] (stopa is analogous to Austrian "Vienna foot" = 0.316080640 metres. [1]);
330 West 42nd Street, also known as the McGraw-Hill Building and formerly the GHI Building, is a 485-foot-tall (148 m), 33-story skyscraper in the Hell's Kitchen neighborhood of Manhattan in New York City, New York, U.S. Designed by Raymond Hood and J. André Fouilhoux in a mixture of the International Style, Art Deco, and Art Moderne styles, the building was constructed from 1930 to 1931 and ...
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 ).
1/2SM indicates the prevailing visibility is 1 ⁄ 2 mi (800 m) SM = statute mile. VCTS indicates a thunderstorm (TS) in the vicinity (VC), which means from 5–10 mi (8–16 km). SN indicates snow is falling at a moderate intensity; a preceding plus or minus sign (+/-) indicates heavy or light precipitation.
TAFs are issued at least four times a day, every six hours, for major civil airfields: 0000, 0600, 1200 and 1800 UTC, [4] and generally apply to a 24- or 30-hour period, and an area within approximately five statute miles (8.0 km) (or 5 nautical miles (9.3 km) in Canada) from the center of an airport runway complex. TAFs are issued every three ...
The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres ( 1 / 1 000 000 m = 0. 000 001 m). To help compare different orders of magnitude , this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers , or μm).

For example, 1 m/s = (1 m) / (1 s) is the coherent derived unit for velocity. [ 1 ] : 139 With the exception of the kilogram (for which the prefix kilo- is required for a coherent unit), when prefixes are used with the coherent SI units, the resulting units are no longer coherent, because the prefix introduces a numerical factor other than one.
