If you leave off the "to light years" conversion, you'll see that the units don't match up. A light year is a measure of distance (m). The result of this equation is 3.86×10^99 s^4/(kg^2 * m^3). How or why Wolfram decided to convert that into 13.82 billion light years is anybody's guess, but it's definitely wrong and nonsensical. You can't convert a s^4/(kg^2 * m^3) unit into just an m without more.



Heads up: click "Use Planck's constant", otherwise Wolfram Alpha assumes h is hours.
