2. Using your average Hubble's constant, calculate the age of the Universe. For this, first, we use the following conversion factors: 1 km =1000 m 1 Mpc = 3.08567758149137×10²² m. 1 km/(s · Mpc) = 3.2407793×10*" 1/s.

My Average Hubbles Constant = 71.0 km / (s x Mpc)

2. Using your average Hubble's constant, calculate the age of the Universe. For this, first,
we use the following conversion factors:
1 km = 1000 m
1 Mpc = 3.08567758149137×10² m.
1 km/(s · Mpc) = 3.2407793×102º 1/s.
Notice the Hubble's constant is measured in units of inverse time. Therefore, the age of
the universe is found via
tage
H
Now using the fomula above and Hve, find the age of the Universe in seconds.

3. Convert this to billions of years. For this, use the conversion factor:
1 billion years = 3.1556952×1016 s

уears
Note, the currently accepted age of the Universe is tage = 13.787±0.020 billion years
within the so-called Lambda-CDM concordance model.
