Age of Universe in Planck normalized units

[Filipe Salles]

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?

Thanks!

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.

according to http://www.wolframalpha.com/input/?i=age+of+the+universe+in+plank+time it is $8*10^{60} t_p$
wolfram alpha is a great resource for that class of problems
