Could someone show me the formula to convert KM to Light-Years? Thanks for any help you can give me.
one light-year is the distance light travels in one year.
Light travels at a speed of 3*10^8 m/s.
In one year, there are 365*24*60*60 seconds.
So one light-year
= 3*10^8 * 365*24*60*60 m
= 9.461*10^15 m
= 9.461*10^12 km (since 1km=1000m)
Light Year is the distance traveled by light in one year.
The speed of light in vacuum is approximately 3 x 10^5 km/s.
And 1 year = 31,536,000 seconds.
Thus,
1 Light-Year = 3 x 10^5 km/s * 31,536,000 s = 9.4608 x 10^12 km
Thank You for the help.
Certainly! To convert kilometers (KM) to light-years, you'll need to use the following formula:
Light-Years = Kilometers / (9.461 × 10^12)
Let me explain how this formula works:
1. Start with the number of kilometers you want to convert.
2. Divide the number of kilometers by the conversion factor of 9.461 × 10^12.
Now, let's apply the formula with an example. Let's say you want to convert 100,000 kilometers to light-years:
Light-Years = 100,000 / (9.461 × 10^12)
To simplify the conversion, let's divide 100,000 by 9.461 × 10^12:
Light-Years ≈ 1.057 × 10^-11
So, 100,000 kilometers is approximately equal to 1.057 × 10^-11 light-years.
Remember to use scientific notation for very large or very small numbers, as it makes it easier to express them.
I hope this explanation helps! If you have any further questions, feel free to ask!
