The age of this (and our) universe can be found from the following simple equation:
The units of Hubble constant are km/(s⋅Mpc).
1) Convert km to m: 1 km/(s⋅Mpc) is 1000 m/(s⋅Mpc).
2) Now convert Mpc-1 to pc-1: 1000 m/(s⋅Mpc)=1000/1000000=0.001 m/(s⋅pc).
3) 1000 m/(s⋅pc) is, therefore, equivalent to 0.001/(3.086×1016) = 3.240×10-20 s-1.
Thus, the age of the universe is
This is
The age is about 14 billion years.
