One light year in miles is 5.87849981 × 10^12 miles and 9.4605284 × 10^12 kilometers
Just in case you would need extra brain flam here you go1 LY = 5874601673400 Miles2 LY = 11749203347000 Miles5 LY = 29373008367000 Miles20 LY = 117492033470000 Miles100 LY = 587460167340000 Miles (See, 1 (400) 100 (40000))SO THAT MEANS 10 LY = 58746016734000)500 LY = 2937300836700000 Miles5700 LY = 33485229538000000 Miles36,000 LY = 211485660240000000 Miles124,000 LY = 728450607500000000 MilesAnd for our final here, 2 million LY is...11749203347000000000I know, It's my speciality.GOING FAR OFF THE TOPIC-Kabob34
The area of Ly Nhan District is 167 square kilometers.
1 LY = 9.46073 * 1012 km (roughly 9.5 trillion km)
5.88 x 1014 miles = 1 ly.1 mile = 1/5.88 x 1014 ly.5.417 x 1014 miles = 5.417 x 1014 /5.88 x 1014 ly = 0.9213 ly
Answer: 25 ly = 236,356,373,887,200 km
Answer: 6.5 ly = 61,452,657,210,672 km
Answer: 0.5 ly = 4,727,127,477,744 km
Answer: 430 ly = 4.065e+15 km
Take the speed of light, 186,000 miles per second, multiply by 3600 then 24 then 365 to get one light year in miles, then multiply by 100,000.
Obviously the closest star is our own sun (Sol) at 149,597,892 kilometers (92,955,820.5 miles). Then comes Proxima Centauri at 4.2 light years, Alpha Centauri A and Alpha Centauri B at 4.3 ly, Barnard's Star at 6 ly and Wolf 359 at 7.7 ly.
Answer: 5,855,000,000 km = 0.000619 ly
11.0 LY = 1.04065 x 1014 km (rounded)
