Microarcseconds to radians
WebArcsecond An arcsecond (denoted by the symbol “) is an anglular measurement equal to 1/3600 of a degree or 1/60 of an arcminute. There are also 206,264.5” in a radian, so that 1” = 4.848 ×10 -6 radians. For observations from the Earth’s surface, turbulence in the Earth’s atmosphere causes point sources (such as stars) to be smeared out and twinkle. http://arcsec2parsec.joseonorbe.com/index.html

WebA degree ( angular degree , unit of angle corresponding to 1/360 of a full circle which is 1/90 of a right angle) is divided into 60 arcminutes ( arcmin , minute of arc, or in context, minute or min ), which, in turn, is divided into 60 arcseconds, making an arcsecond 1/3600 of a degree or 1/1296000 of a full circle, or 2π/1296000 of a radian. WebMay 4, 2024 · Divide both sides of this equation by 180. You get: 1 ∘ = π 180 radians. You can use this to convert the measure of an angle from degrees to radians. For example, if you wanted to convert 30 ∘ to radians, you could multiply both sides by 30: 30 ∘ = 30 ⋅ π 180 radians = 30π 180 radians = π 6 radians.
WebD = 1.22 * 1.304 x 10^-3 meters / (1.435 x 10^-12 radians) = 1.110 x 10^7 meters. Therefore, the diameter of the telescope needed to achieve an angular resolution of 1.435 x 10^-12 radians at a wavelength of 1.304 millimeters is approximately 1.110 x 10^7 meters. This is equivalent to about 14,957 Earth radii.
