» John_Croft - Using Hubble Constant to calculate Universal Age

The formula for using the Hubble Constant to calculate age of the universe is supposed to be

T = 1/H

(where T = Age of Universe, H = Hubble Constant)

Given the recently accounced Nasa report on H as 70 kms/sec per Megaparsec,

Then 1/70 = 0.01428571428571

How does this get converted into Age of the Universe (as Billions of Years?)

Thanks

John
