meters, feet, and even miles are way too small to measure distances in space. astronomical units are mostly used to measure distances in our solar system. light years are used to measure the distances of things further away from our solar system.
For small distances, e.g. Earth to Moon, scientists use miles of kilometers. For larger distances, e.g. the orbit diameter of Jupiter, they use the "AU" or Astronomical Unit, which is the distance from the Sun to Earth. For enormous distances, astronomers use the lightyear, which, although it sounds like a time unit, is truly a distance unit. A lightyear is the distance light travels in one year, or 5.87849981 × 1012 miles. Another unit for large distances is the Parsec, which is 3.26 lightyears.
Scientists use properties such as luminosity, temperature, mass, size, and spectral characteristics to group stars. These properties help categorize stars into different classes based on their similarities and differences.
Scientists use astronomical units (AU) to provide a standard measure of distance within our solar system, where the average distance from the Earth to the Sun is defined as one AU (approximately 93 million miles or 150 million kilometers). This unit simplifies calculations and comparisons of distances between celestial bodies, making it easier to communicate and understand vast distances. Using AU helps avoid the cumbersome numbers typically associated with miles or kilometers when dealing with the scale of space.
Because stars are much, much further away than planets are. What sounds better? The nearest star is 4.24 lightyears away or 40,132,658,900,000 (Or 4.013x10^13) kilometers? To go even deeper, it's better to give distance in astronomical units (1 au = Mean distance from Sun to Earth), megameters (1Mm = 1,000km) or gigameters (1Gm = 1,000,000km) when refering to planets. When refering to distance, it's best and least confusing to use smaller units. If you reference somoething extremely far away, you would often use parsecs (Be it parsecs, megaparsecs, etc.). where 1 parsec = 3.2 lightyears.
You can use kilometers if you like. On the other hand, distances within the Solar System are often quoted in AU (astronomical units), where 1 astronomical unit is the distance from Sun to Earth. Such distances are easier to visualize.
They use lightyears and AU (Astronomical Units). They use kilometers, AU's and light years!! *Parsecs are also commonly used

I think it is because The Universe is so GIANT that earth measures just aren't enough. I hope I helped!
You use math in astronomy to measure the amount of astronomical units(150,000,000 km). Such as, the Earth is 1.5 astronomical units away from the sun.
When exploring space, astronomers use astronomical units, (AU) to measure the distance from one object to another. Since every distance from one object in our solar system to another object in our solar system, the distance of a planet from the sun would be measured in astronomical units

The purpose of using astronomical units by Astronomers is mainly to make comparisons about the distance between all celestial bodies that they can detect and study. This include galaxies. The main astronomical unit is the Light year. The calculation of astronomical distance involves highly complex mathematical formulas.
You can use astronomical units or light years.
scientists frequently use Celsius
the units used are light seconds, minutes, hours and astronomical units.
The name for the units scientists use for circles are degrees.
To measure temperature, scientists use:KelvinCelsiusFahrenheit.
