#1.92 X 10^13# miles = 19.2 trillion miles, nearly. Show Explanation:1 parsec = 206264.81.AU = 206264.81 X 92955807.27 miles = #1.91735119 X 10^13# miles = #1.917 X 10^13# miles, nearly. For the conversion #parsec to AU#, the factor is #3600 X (180/pi) # and this is also the factor for #radian to sec# conversion.. Note
that (1 parsec X 1'' exprressed in radian) = 1 AU.
AUAU, which stands for "astronomical unit", is a unit for measuring distance. One AU is the average distance from the Sun's center to the Earth's center. It is equal to 149,597,871 km (92,955,807 miles). AUs are often more convenient to use than kilometers when measuring large distances such as those in space. In this case kilometers are just too small - it would be like measuring the distance from Boston to San Francisco in inches. AUs simply make a measurement easier to understand and give you something to compare it to. For example, Saturn's orbit around the Sun has an average radius of 9.5 AU, which means that Saturn is about ten times farther from the Sun than Earth is. The average distance from the Sun to distant Pluto is about 40 AU. Mercury, the planet closest to the Sun, orbits at an average distance of 0.39 AU. AUs are generally used for measurements of distances within our Solar System. Distances to stars are much larger, and are expressed in terms of light years. One light year is equal to more than 63,000 AUs. The nearest star, Proxima Centauri, is just over 4 light years away.

However, the average distance from Earth to the sun is about 93 million miles (150 million kilometers). Scientists also call this distance one astronomical unit (AU).
How do you calculate distance in AU?One AU is the mean distance from the center of the Earth to the center of the Sun. This distance was most recently defined in 2012 by the International Astronomical Union to be 92,955,807.27 miles (149,597,870.7 kilometers).
What is distance of 1 AU expressed in parsec?Distances expressed in fractions of a parsec usually involve objects within a single star system. So, for example: One astronomical unit (au), the distance from the Sun to the Earth, is just under 5×10−6 pc. The most distant space probe, Voyager 1, was 0.000703 pc from Earth as of January 2019.
What do you mean by 4 AU?4 au means 4 astronomical units. Explanation: astronomical unit is a parameter used to measure distances in space. an astronomical unit is equal to the distance of sun and earth and it is smaller than a light year.
