That's probably a bit confusing. You can edit this Venn Diagram using Creately diagramming tool and include in your report/presentation/website. We assume you are converting between light year and astronomical unit. Between ly and au - ua measurements conversion chart page. A light year is the distance light travels in a year. A Venn Diagram showing The differences between an Astronomical unit and a Light year. A light year (ly) equals 10,000,000,000,000 km, or 10¹³ km. What we use with an AU is to measure the distances in space. Astronomical units are usually used to measure distances within our Solar System. Let's take the Earth for an example. An astronomical unit is equivelent to the Earth's distance from the Sun on average, or 93 million miles, approximately 8 light minutes. Diferent length units conversion from light-year to astronomical units. You can view more details on each measurement unit: light-year or astronomical unit The SI base unit for length is the metre. Convert From Light Year. There is a constant, the unit distance, of the value of one astronomical unit. The "astronomical unit" is a unit of distance defined in terms of the Earth's distance from the Sun. The answer is 1.5812507408869E-5.

Lesson Summary Measuring the distances between astronomical objects is difficult. One light-year is equivalent to roughly 63 thousand astronomical units.

One light year is equivalent to 9,461,000,000,000 km or 5,878,000,000,000 miles. One astronomical unit is the distance Earth-Sun; it takes light a bit more than 8 minutes to travel that distance. Light Year - A unit of measurement of distance in astronomy, which a ray of sunlight passes for a year (365 days). 2: Enter the value you want to convert (light year). An Astronomical Unit (AU) is the average distance between Earth and the Sun, which is about 93 million miles or 150 million kilometers. A light year is the distance light will travel in a year, the speed of light is just under 300 000 kilometres per second, so light travels one astronomical unit in just over eight minutes. A light-year, of course, is the distance light travels in a year. Calculate from distance into other astronomy length unit measures. convert from Astronomical Unit to Light Year conversion of Astronomical Unit to Light Year Astronomical Unit to Light Year Astronomical Unit into Light Year Astronomical Unit in Light Year conversion from Astronomical Unit to Light Year au to ly. Light years, astronomical units and parsecs are the three most common ways of measuring distances in astronomy.

The average AU is 149,597,871 kilometers. Astronomical units are used more than light years because AU's are used in our solar system only and light years go beyond that. Earth’s orbit around the sun isn’t a perfect circle. Astronomical unit definition, a unit of length, equal to the mean distance of the earth from the sun: approximately 93 million miles (150 million km). More exactly, one astronomical unit (AU) = 92,955,807 miles (149,597,871 km).
