Astronomical Unit Conversion

The Free Online Astronomical Unit Converter helps you convert one measuring astronomical unit into another measuring unit.

You can convert between parsec, astronomical unit (AU), kilometer (km), meter (m), mile (mi), light-year (Julian), light-year (traditional), light-year (tropical/solar), and support many other conversions.

Instantly convert one unit to all others.

What do you mean by the Astronomical Unit?

To measure the distance from one point to another, we use some units for calculating. Astronomers adopt the same method to measure the objects' distance (planets, dwarf planets, asteroids, comets, spacecraft, etc.) within our solar system. And that is measured in terms of the astronomical unit.

Therefore, the astronomical unit measures how far the object is and is a mean/average distance between the earth and the sun.

one astronomical unit (AU) = 92,955,807 miles

It is expressed by 149,597,871 km, and it approximately equals eight (8) light minutes.

One light year = 63,240 AU

What is meant by perihelion and aphelion?

Our earth orbits around the sun, but that orbit is not a perfect circle. Therefore, the earth's distance from the sun does not remain the same for the whole year, but it keeps changes throughout the year.

Therefore, the astronomers calculate and provide the earth's changing distance throughout the year concerning the astronomical unit.

Perihelion: the earth is 0.983 AU away from the sun when it is at its nearest point to the sun for the year, in January.

Aphelion: the earth is 1.017 AU away from the sun when it is at its farthest point to the sun for the year, in July.

Units of measurement

The astronomers adopt the astronomical unit (the unit of length) to measure the objects' distance (planets, dwarf planets, asteroids, comets, spacecraft, etc.).

However, other measuring units like kilometer, light-second, light-minute, light-hour, light-day, light-year [Julian], light-year [tropical], light-year [traditional], parsec, meter,1, and mile are used to measure the distance.

one astronomical unit (AU)

= 149597870700 meters

≈ 92955807 miles

≈ 499.00478384 light-seconds

≈ 4.8481368×10−6 parsecs

≈ 1.5812507×10−5 light-years

Mean distance of significant planets from the sun

As the astronomers adopt the astronomical unit to measure the distance of the planets in our solar system, so the mean distance of significant planets from the sun is

  • Mercury = 0.387 AU
  • Venus = 0.723 AU
  • Earth = 1.000 AU
  • Mars = 1.524 AU
  • Jupiter = 5.203 AU
  • Saturn = 9.582 AU
  • Uranus = 19.201 AU
  • Neptune = 30.047 AU

Mean distance of dwarf planets from the sun

The astronomers use the term dwarf planet for the object that is round and orbits around the sun. But like other planets, that object technically fails to qualify as a planet. They are

  • Ceres = 2.767 AU
  • Pluto = 39.53 AU
  • Eris = 67.958 AU
  • Sedna = 518.57 AU

Online conversion tool V/S Manual conversion, which one is better?

After the technological revolution, the most significant change that happened is that the machine replaces the human. And we brought the standards in our lives by moving from estimated calculations to proper and accurate calculations.

Even though the machines are built and programmed by humans, therefore, they are preferred over humans because they give you accurate and correct results within no time.

The astronomical unit (the unit of length)is the unit used to measure the objects' distance (planets, dwarf planets, asteroids, comets, spacecraft, etc.) in our solar system.

However, other measuring units like kilometer, light-second, light-minute, light-hour, light-day, light-year [Julian], light-year [tropical], light-year [traditional], parsec, meter, and mile, etc., are used to measure the distance.

Moreover, sometimes, you have to convert one measuring unit of frequency into another measuring unit. Here the online astronomical unit converter helps you a lot for accurate and precise conversion.

How to convert parsecs to kilometers (pc to km) using an online astronomical unit converter tool?

An online astronomical unit converter tool makes the conversion process easy. You can easily convert one measuring astronomical unit to another measuring unit within no time.

To do this, follow the below-mentioned steps.

  • Open the Online Astronomical Unit Converter Tool.
  • Enter the amount 1 in the first column.
  • In the second column, "Select from," select parsecs (pc) as a measuring unit from which you want to convert.
  • In the third column, "Select to," select kilometers (km) as a measuring unit in which you want to convert.
  • Click on the "convert" button; the result will be 30856774878504.977 kilometers (km) within no time.

Therefore, 1 parsecs (pc) = 30856774878504.977 kilometers (km).

However, some essential conversions using that tool are

  • 1 kilometers (km) = 0.6213711922 miles (mi)
  • 1 mile (mi) = 1.609344 kilometers (km)
  • 1 light-year [traditional] = 5874601673407.301 miles (mi)

Note: The same procedure will be adopted in conversion between kilometer, light-second, light-minute, light-hour, light-day, light-year [Julian], light-year [tropical], light-year [traditional], parsec, meter, and mile.
