# How do you solve for Hubble's constant?

##### 1 Answer

If a galaxy is at a distance of P parsec, the angular spacing of its span will be P''. Observe the same galaxy 1 year later, for the angular span Q''. Now, see the explanation..

#### Explanation:

If a galaxy is at a distance of P parsec, the angular spacing of its span will be P''. Observe the same galaxy 1 year later, for the angular span Q''. Q is just very little over P

Now, the relative measure

It is easy to see that the dimension of

From different sources, this is estimated to be 68 or 70 or 71 or 72 in standardized units km/s/mega parsec.

I have found reciprocals

The lateral (span) expansion of galaxy/cluster observed is

The purpose of making this note here is to convey what I have understood about
