The Hubble's Law calculator computes the recessional velocity of a galaxy (v) based on the Hubble Constant (H) and the distance to the galaxy (d).

INSTRUCTION: Choose units and enter the following:

  • (H)  The Hubble Constant is the velocity per mega-parsec (Usually in the range of 70 km/s or 71 km/s per megaparsec.)
  • (d)  This is the distance to the galaxy.

Velocity of Recession (v): The calculator returns the velocity in meters per second.    However, this can be automatically converted to other velocity units via the pull-down menu.
