100 quintillionths of a light year are in a meter http://en.wikipedia.org/wiki/Light-year
One meter is about 0.000,000,000,000,000,105,7 light-years.Calculation: As a light-year is 9,460,730,472,580,800 meters, one meter equals 1/9,460,528,400,000,000 light-years = 1.057,000,834,024,615,4 × 10-16 light-years - or about 105.7 atto-light-years.
5.8e3 light years
Use this conversion: light-years x 9,460,730,472,580,800 = metres
from the book
It depends on 0.1 whats. There will be a different number of 0.1 kilometres, 0.1 micrometres, 0.1 miles, 0.1 light years, etc
To calculate how far away stars are from Earth.
Multiply the number of years by 365 days
The number of years in a second... by definition!
Don't even try it. That is why we use light years to calculate distance. Your calculator will melt if you try.
Take the number of months and divide by 12 to find the years.
Each light-year has approximately 9.5 x 1012 kilometers. You can multiply the number of light-years by that number.
1 light-year is about 5.88 x 1012 miles. To convert a certain number of light-years to miles, you can multiply by this number.
