I promise you that the unit known as a light-year is a measure of distance.

I promise you that the unit known as a light-year is a measure of distance.

And all this time I thought it meant a year that isn't a leap year, so it's "light" and has only 356 days. Golly, live and learn!

I promise you that the unit known as a light-year is a measure of distance.

I find it astonishing that discussions of this type, to correct such obscene knowledge gaps as these, are still necessary.

Google has a new conversion tool - if you input units of measurement it will convert from one to the other - if you input lightyear to inches, it will output:

1 lightyear = 3.72461748 × 1017 inches (that's ten to the 17th)

If you input hour to seconds, it will output:

1 hour = 3 600 seconds

But if you input lightyear to seconds, it won't give you a response.
