How to use this Lightyears to Astronomical Units Converter 🤔

Follow these steps to convert given length from the units of Lightyears to the units of Astronomical Units.

1. Enter the input Lightyears value in the text field.
2. The calculator converts the given Lightyears into Astronomical Units in realtime ⌚ using the conversion formula, and displays under the Astronomical Units label. You do not need to click any button. If the input changes, Astronomical Units value is re-calculated, just like that.
3. You may copy the resulting Astronomical Units value using the Copy button.
4. To view a detailed step by step calculation of the conversion, click on the View Calculation button.
5. You can also reset the input by clicking on Reset button present below the input field.

What is the Formula to convert Lightyears to Astronomical Units?

The formula to convert given length from Lightyears to Astronomical Units is:

Length_{(Astronomical Units)} = Length_(Lightyears) / 0.000015812507410087428

Substitute the given value of length in lightyears, i.e., Length_(Lightyears) in the above formula and simplify the right-hand side value. The resulting value is the length in astronomical units, i.e., Length_{(Astronomical Units)}.

Calculation

Calculation will be done after you enter a valid input.

Examples

1

Consider that a distant exoplanet is located 4.5 lightyears away from Earth.
Convert this distance from lightyears to Astronomical Units.

Answer:

Given:

The length in lightyears is:

Length_(Lightyears) = 4.5

Formula:

The formula to convert length from lightyears to astronomical units is:

Length_{(Astronomical Units)} = Length_(Lightyears) / 0.000015812507410087428

Substitution:

Substitute given weight Length_(Lightyears) = 4.5 in the above formula.

Length_{(Astronomical Units)} = 4.5 / 0.000015812507410087428

Length_{(Astronomical Units)} = 284584.8469

Final Answer:

Therefore, 4.5 ly is equal to 284584.8469 AU.

The length is 284584.8469 AU, in astronomical units.

2

Consider that the nearest star, Proxima Centauri, is about 4.24 lightyears from our solar system.
Convert this distance from lightyears to Astronomical Units.

Answer:

Given:

The length in lightyears is:

Length_(Lightyears) = 4.24

Formula:

The formula to convert length from lightyears to astronomical units is:

Length_{(Astronomical Units)} = Length_(Lightyears) / 0.000015812507410087428

Substitution:

Substitute given weight Length_(Lightyears) = 4.24 in the above formula.

Length_{(Astronomical Units)} = 4.24 / 0.000015812507410087428

Length_{(Astronomical Units)} = 268142.1668

Final Answer:

Therefore, 4.24 ly is equal to 268142.1668 AU.

The length is 268142.1668 AU, in astronomical units.

Lightyears

A light-year is a unit of length used in astronomy to measure vast distances. One light-year is equivalent to approximately 9.461 trillion kilometers or about 5.879 trillion miles.

A light-year is defined by the distance that light travels in a vacuum in one year, which is about 9.461 × 10^12 kilometers.

Light-years are used to measure distances between stars, galaxies, and other celestial objects. They provide a convenient way to express astronomical distances, making it easier to understand the scale of the universe.

Astronomical Units

An astronomical unit (AU) is a unit of length used in astronomy to measure distances within our solar system. One astronomical unit is equivalent to approximately 149,597,870.7 kilometers or about 92,955,807.3 miles.

The astronomical unit is defined as the mean distance between the Earth and the Sun.

Astronomical units are used to express distances between celestial bodies within the solar system, such as the distances between planets and their orbits. They provide a convenient scale for describing and comparing distances in a way that is more manageable than using kilometers or miles.

  "x_long_desc": "A light-year is a unit of length used in astronomy to measure vast distances. One light-year is equivalent to approximately 9.461 trillion kilometers or about 5.879 trillion miles. </p><p>A light-year is defined by the distance that light travels in a vacuum in one year, which is about 9.461 × 10^12 kilometers.</p><p>Light-years are used to measure distances between stars, galaxies, and other celestial objects. They provide a convenient way to express astronomical distances, making it easier to understand the scale of the universe.",
  "y_long_desc": "An astronomical unit (AU) is a unit of length used in astronomy to measure distances within our solar system. One astronomical unit is equivalent to approximately 149,597,870.7 kilometers or about 92,955,807.3 miles. </p><p>The astronomical unit is defined as the mean distance between the Earth and the Sun.</p><p>Astronomical units are used to express distances between celestial bodies within the solar system, such as the distances between planets and their orbits. They provide a convenient scale for describing and comparing distances in a way that is more manageable than using kilometers or miles."
