How is the Hubble constant converted to years?

Answer 1

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.

The distance unit is mega parsec. One year is equal to 356.256 X 24 X 60 X 60 s = 31558118 s. The answer is 71 X 31558118.

The Hubble constant is commonly expressed in terms of kilometers per second per megaparsec (km/s/Mpc). To convert it to years, use the following formula: [1 \text{ Mpc} = 3.08567758 \times 10^{19} \text{ kilometers}] [1 \text{ year} = 3.15576 \times 10^{7} \text{ seconds}] Next, divide the speed of light in terms of kilometers per second (299,792 km/s) to obtain megaparsecs. Megaparsecs can then be converted to years by multiplying the result by the number of seconds in a year.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
