If you could travel at the speed of light, you would be able to circle the Earths equator about 7.5 times in just one second! Multiply them together and you get km in a light year. How far is that? In other words, a light-second is the distance light travels in one second, or 7.5 times the distance around Earths equator.
One light year is 9.5 million million km, so multiply the number of light years by 9.5 million million (or 9.5 trillion). So for 1 we have: (1 47303652362904) 5 = 47303652362904 5 = 9460730472580.8 Kilometers, So finally 1 light year = 9460730472580.8 km, 2023 UnitChefs. This distance is referred to as one light year.

A light-year is the distance light travels in one Earth year. think that I will be visiting again. The speed of light is constant throughout the universe and is known to high precision. 
He may have resisted expressing distances in light-years because it would reduce the accuracy of his parallax data due to multiplying with the uncertain parameter of the speed of light. The star was 61 Cygni, and he used a 160-millimetre (6.2in) heliometre designed by Joseph von Fraunhofer. If you want to know the distance of a light year in kilometers, you will need to find the speed of light in kilometers per second. This cookie is set by GDPR Cookie Consent plugin.

[20] He recognized that his readers would enjoy the mental picture of the approximate transit time for light, but he refrained from using the light-year as a unit. A daily update by email. The distance that light travels in a second is about 186,000 miles, making that the distance of a light second. So it contains exactly 365.25 days. Each day contains 86400 seconds (60 60 24) and light travels at exactly 299792458 meters per second, meaning that a light year is equal to exactly 365.25 86400 299792458 = 9460730472580800 meters. If the average Gregorian Year was used instead, a light-year would be 9460536207068016 meters. Type in your own numbers in the form to convert the units! Research source
