Because the inch, foot, meter, kilometer, and mile are all too small, and the light year is too big.
All of those produce inconvenient numbers when used to measure distances in the solar system.
Mercury's average distance from the sun is:
36,000,000 miles
57,900,000 kilometers,
0.000006124 light year
0.387 AU.
Pluto's average distance from the sun is:
3,670,000,000 miles
5,910,000,000 kilometers
0.0006247 light year
39.46 AU.
An astronomical unit (AU) is commonly used to measure distances within our solar system, particularly between the Earth and other celestial bodies. One AU is approximately equal to the average distance from the Earth to the Sun, about 93 million miles or 150 million kilometers. It simplifies calculations and comparisons of distances in space, making it easier to express the vast distances involved in astronomy. For example, distances to planets, asteroids, and comets are often given in AUs to provide a clearer understanding of their relative positions.
Probably AUs or Astronomical Units. 1AU= 93 million miles or about 150 million km. 1AU is the distance from the Earth to the Sun.
AUS 8A is a Japanese stainless steel known for its corrosion resistance and toughness, while 440 stainless steel is a high-carbon stainless steel often used in knife blades due to its hardness and wear resistance. AUS 8A is easier to sharpen but may not hold an edge as well as 440 stainless steel.
AUS-8 steel can rust if not properly maintained due to its carbon content and lack of corrosion resistance compared to other stainless steels. Factors such as exposure to moisture, salts, and acidic environments can contribute to rusting on an AUS-8 blade. Regular cleaning, drying, and oiling can help prevent rust on AUS-8 steel.
It's going to vary, depending on where they are in their orbits. At their closest they will be around 4.3AU while at opposite sides of the solar system they will be around 14.7AU. 1 AU = earth to sun distance of around 93 million miles.
The acronym AUS is mostly used to describe either the country Australia or the country Austria. AUS is also used when describing an abdominal ultrasound.

Because it would be impractical (very large numbers) to use kilometers, miles, or meters to measure distances in our solar system. This unit of measurement is used as it allows for comparisons to be done with relative ease, and all distances can be standardized. For this same reason when talking about anything outside of the solar system, light-years are used as the distances become drastically larger and too much for AUs to handle.
The AU was used as a unit of measure, before the propagation of electromagnetic radiation was understood, or its rate quantified. So because of tradition, and the fact that the AU is a more wieldy unit, for distances within the solar system than either light years, or miles, the AU still holds sway.
The idea here is to have "manageable" units - the official international unit of length is the meter, but it's a bit hard to imagine a huge number such as 4e15 meters, (4 x 10 to the power 15) meters, for instance. Astronomical units are typically used within the Solar System; light-years (or parsecs, which are more common in professional astronomy) are typically used outside the Solar System.
We like to measure things in convenient numbers, without lining up TOO many zeroes. So we measure the distance from home to work in miles or kilometers, not inches or centimeters. We measure the distance from Earth to the other planets in AU rather than in miles, and we measure the distances to the stars in light years rather than in miles or AU. An even larger unit, the megaparsec, is used to describe the distance to very distant galaxies.
