How is the Hubble constant converted to years?
Hubble constant is dimensional. It is approximated as 71 km/s/mega parsec. Converting time unit to Earth year, it becomes 2.2406 E+09 km/year/mega parsec.
Mega parsec is distance unit. 1 year = 356.256 X 24 X 60 X 60 s =31558118 s.Answer is 71 X 31558118.
