The baseline B and distance d must be in the same units of length. star parallax relation: parallax angle p in arc seconds = B / d. The baseline B is in units of A.U. and the distance d is in units of parsecs. For measurements from the Earth, B = 1. star distance d = B / p. http://astronomyonline.org/science/smallangleformula.asp

WebbThe Small Angle Formula In astronomy, the sizes of objects in the sky are often given in terms of their angular size as seen from Earth, rather than their actual sizes. For a given … In astronomy, the sizes of celestial objects are often given in terms of their angular diameter as seen from Earth, rather than their actual sizes. Since these angular diameters are typically small, it is common to present them in arcseconds (″). An arcsecond is 1/3600th of one degree (1°) and a radian is 180/π degrees. So one radian equals 3,600 × 180/ arcseconds, which is about … greater than or equal to symbol javaWebbSmall angle formula units. Both formulas only work for small angles.

"In astronomy, the angular size or angle subtended by the image of a distant object is often only a few arcseconds, so it is well suited to the small angle approximation. The linear size (D) is related to the angular size (X) and the distance from the observer (d) by the simple formula: where X is measured in arcseconds. The number 206265 is approximately equal to the number of arcseconds in a circle (1296000), di… " - Small angle formula 206265
