71 kilometers per second per megaparsec convert to mph?

Answer:
71 km/s per megaparsec is an acceleration, not a velocity.

Key this into the Google task bar:
convert 71 km per second to miles per hour

Out pops:

158,822.477 miles per hour

In each case this would be the acceleration over a megaparsec (about 3 million light years)

Sounds about right for the Hubble Constant.
