Multiply by 0.6214 to get miles = 22 trillion miles

I’m sure they have the right number. Mine was a ballpark estimate, as one does in physics. I think Proxima Centauri is about 4.2ly from Earth.

I was just doing the extra conversion because the comic is in miles. The figures are pretty close, and the extra .2ly would account for the discrepancy. Looks good to me!

Yes, too much rounding will do that (also the approximation of a year shaved off more than a percent). Taking more precise numbers, it fits:

4.2465 ly * 365.2425 days/yr * 24 * 3,600 * 299,792,458 km/s * 0.6214 ~ 24.96 e15 miles
