"light-year"
The distance light travels in one year is called a light-year. To get the number 9,470,000,000,000, the unit used is the kilometer.
You cannot 'measure' light. However, there is the light-year, a measurement of the distance light can travel in one year. there are many. Lumens, cadlepower, foot candles and candelas. There are probably a few more.
It would not because a light year is too large a unit. A more appropriate measurement unit is the Astronomical Units (AU), the average distance from the Sun to the Earth.The Solar system is thought to extend to the Oort Cloud, a theorised collection of icy objects which orbit the sun at a distance of approx 1.9 light years = 100,000 AU.The Heliopause, which is the distance at which the Solar Wind, (the Sun's radiation) is stopped by the interstellar medium, is only around 120 AU.The outermost planet, Neptune, has a radius of approx 30 AU = 0.0005 light years - an indication that a light year is not an appropriate measurement unit..
No. A light-year is a measurement. A light year is a distance measurement based on how far light travels in a year.
The unit of measurement is the "light year".

A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.

The unit of measurement used to measure distances between galaxies is typically the light-year, which is the distance that light travels in one year. This unit is used because of the vast distances involved in intergalactic space.
The most appropriate unit of measurement for distances between the Milky Way galaxy and other galaxies is the light-year. A light-year is the distance that light travels in one year, approximately 5.88 trillion miles (9.46 trillion kilometers). This unit is suitable because astronomical distances are vast, and using light-years allows for a more comprehensible scale when discussing intergalactic distances. For even larger scales, astronomers may also use megaparsecs, where one megaparsec equals about 3.26 million light-years.

Light Year is unit for all astronomic distances
