How fast is expansion of the universe?

Answer 1

Asher Cohen

#H_theta ~~ 70 ((km)/s)/(Mpc)#

The Hubble constant, which equals roughly 70 km/s per MegaParsec, indicates the rate of expansion.

The Hubble constant, which is used to calculate the expansion rate of the universe, is currently estimated to be approximately 67.4 km/s per megaparsec. This means that galaxies are expanding away from us at a rate of 67.4 km/s for every megaparsec, or 3.26 million light-years, that separates us from them.
