The similar term "science writing" instead refers to writing about a scientific topic for a general audience; this could be by scientists and/or journalists, for example.) Scientific writing is a specialized form of technical writing, and a prominent genre of it involves reporting about scientific studies such as in articles for a scientific ...

On Uranus, northern hemisphere wind speeds reach as high as 240 meters per second (540 mph) near 50 degrees north latitude. [166] [167] [168] At the cloud tops of Neptune, prevailing winds range in speed from 400 meters per second (890 mph) along the equator to 250 meters per second (560 mph) at the poles. [169]
Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
One such example exists on the ice roads in Estonia, where it is advised to avoid driving at the speed of 25–40 km/h (16–25 mph) as the vehicle may create resonance that may in turn induce the breaking of ice. This means that two sets of speeds are allowed: under 25 km/h (16 mph) and between 40–70 km/h (25–43 mph). [68]

The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second.
