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).
A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...
The benz, named in honour of Karl Benz, has been proposed as a name for one metre per second. [10] Although it has seen some support as a practical unit, [11] primarily from German sources, [10] it was rejected as the SI unit of velocity [12] and has not seen widespread use or acceptance.
(The Center Square) – Wisconsin Gov. Tony Evers said he intends to propose spending $80 million on farms, farm families, processors and producers in his upcoming biennial budget proposal ...
[2] [3] At its deepest, it is more than 360 feet (110 m) deep, although the official measurement is uncertain. [ 4 ] [ 5 ] The lake is over 7 miles (11 km) long and averages 1 mile (1.6 km) in width, and is accessible via a solitary landing area located on the south end. [ 5 ]
The UK statute chain is 22 yards, which is 66 feet (20.1168 m). This unit is a statute measure in the United Kingdom, defined in the Weights and Measures Act 1985. [6] One link is a hundredth part of a chain, which is 7.92 inches (20.1168 cm).
An Earth mass (denoted as M 🜨, M ♁ or M E, where 🜨 and ♁ are the astronomical symbols for Earth), is a unit of mass equal to the mass of the planet Earth. The current best estimate for the mass of Earth is M 🜨 = 5.9722 × 10 24 kg, with a relative uncertainty of 10 −4. [2] It is equivalent to an average density of 5515 kg/m 3.
In 1976, as construction went on, the bridge was named for Francis Scott Key, the author of "The Defence of Fort M'Henry", the poem upon which "The Star-Spangled Banner" is based. Key was inspired to write the poem after witnessing the bombardment of Fort McHenry during the Battle of Baltimore in September 1814. [ 22 ]
