2.932*10-16 light years * 299,792.458 km = .000000087899148686 km = 8.789*10-8 km ■
To convert kilometers to light years, divide the distance in kilometers by the number of kilometers in a light year, which is approximately 9.46 trillion kilometers. Thus, 33.11 trillion kilometers is about 3.49 light years away (33.11 trillion km ÷ 9.46 trillion km/light year ≈ 3.49 light years).
To convert to light-years, divide the kilometers by 9.5 x 1012. Divide the result by 3.26 to convert to parsecs.
To convert light years to kilometers, you would multiply the number of light years by about 9.461 trillion kilometers. Therefore, 6.5 light years is approximately equal to 61.55 trillion kilometers from Earth.
5.3 light-years is the distance in that case. If you want to convert that to kilometers, you can multiply the distance in light-years by 9.5 x 1012.

Two Light Years = 18,921,460,945,161.6 Kilometers.
About 83 trillion kilometers in 8.8 light years.
About 100,000 light-years in diameter. (If you want to convert that to kilometers, multiply by 9.5 x 1012.)
Light travels at a speed of 300,000 kilometers per second. To convert 57 trillion kilometers to light years, we divide by the speed of light: 57 trillion km / 300,000 km/s = 190 million seconds. Converting this to years, it would take approximately 6 years to travel 57 trillion kilometers in light years.
The star won't normally "travel the 37 light-years to Earth". 37 light-years would most likely be the distance from the star to Earth; it takes light from the star 37 years to reach us. Please note that a light-year is a unit of distance; it is NOT a unit of time. To convert from light-years to kilometers, multiply the number of light-years by 9.5 x 1012.
1 light-year = 9.46*1012 kilometers 50,000 light-years = 4.73*1017 kilometers
