The project I was running was designed to extract this information for all the galaxies in a many cubic megaparsec volume of the local Universe. From Wordnik.com. [Well, That was Fun.] Reference
Currently, most astronomers agree that the value of the Hubble constant is about 71 kilometers per second per megaparsec a megaparsec is 3.2 million light-years. From Wordnik.com. [The Big Honkin’ Universe « UDreamOfJanie] Reference
The expansion rate became known as the Hubble constant; Hubble thought it was 500 kilometers per second every 3.26 million light-years, that is, every megaparsec. From Wordnik.com. [A Grand and Bold Thing] Reference
Therefore, since the curvature of the universe is essentially set by its expansion rate, the expansion rate of the universe determines how far away assuming special relativity works (which is typically as far as the expansion is negligible, so within a megaparsec or so, and also far away from any really dense objects, such as black holes or neutron stars).

At a speed of 15,000km s-1, how many megaparsec would the searation between the earth and galaxy change?. From Wordnik.com. [Yahoo! Answers: Latest Questions] Reference
The new measure of the Hubble constant, 74 kilometers per second per megaparsec (plus or minus 3.5), indicates that the universe is about 350 million years younger than the previous 13.7 billion-year estimate, Riess says.

V = Hd where the velocity and distance (v, d) are related by this constant H = 64km/sec/Mpc. For for every megaparsec (1pc = 3.26 ly and the distance out to where one AU subtends a one second arc) the further out one observes that galaxies are moving an average of 64 km/sec faster.
