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).
61 000 Mm 2 Surface area of Jupiter , [ 93 ] the "surface" area of the spheroid (calculated from the mean radius as reported by NASA). The cross-sectional area of Jupiter, which is the same as the "circle" of Jupiter seen by an approaching spacecraft, is almost exactly one quarter the surface-area of the overall sphere, which in the case of ...
65 miles (105 km) Components; Serial no. 13: The V-2 No. 13 [1] was a modified V-2 rocket that became the first object to take a photograph of the Earth from outer space.
JB2008 is a newer model of the Earth's atmosphere from 120 km to 2000 km, developed by the US Air Force Space Command and Space Environment Technologies taking into account realistic solar irradiances and time evolution of geomagnetic storms. [14] It is most useful for calculating satellite orbital decay due to atmospheric drag. Both CIRA 2012 ...

SI, and hence the use of "km/h" (or "km h −1 " or "km·h −1 ") has now been adopted around the world in many areas related to health and safety [36] and in metrology [37] in addition to the SI unit metres per second ("m/s", "m s −1 " or "m·s −1 "). SI is also the preferred system of measure in academia and in education.
