Age of Universe in Planck normalized units

  1. Sep 7, 2015 #1
    Hello, I've a problem.

    I need to find the age of universe in normalized Planck units. In my case, I'm using Planck mass = 1 and:

    ##H = 1.18 × 10^{-61} \times t_P^{- 1}##

    With these values, how can I find the age of the universe?

    Google for "age of universe", then for "Planck time". That will get you two numbers, and from there it's just a bit of arithmetic.
